JDT Core options

JDT Core options control the behavior of core features such as the Java compiler, code formatter, code assist, and other core behaviors.  The APIs for accessing the options are defined in JavaCore.  Options can be accessed as a group as follows:

Options can also be accessed individually by a string name.

Options that can configure the severity of a problem can also be found.

Options are stored as a hash table of all known configurable options with their values. Helper constants have been defined on JavaCore for each option ID and its possible constant values.

The following code fragment restores the value of all core options to their defaults except for one (COMPILER_PB_DEPRECATION), which is set specifically.


   // Get the default options
   Hashtable options = JavaCore.getDefaultOptions();
   
   // Change the value of an option
   options.put(JavaCore.COMPILER_PB_DEPRECATION, JavaCore.ERROR);
   
   // Set the new options
   JavaCore.setOptions(options);

The following code fragment keeps the value of the current options and modifies only one (COMPILER_PB_DEPRECATION):


   // Get the current options
   Hashtable options = JavaCore.getOptions();
   
   // Change the value of an option
   options.put(JavaCore.COMPILER_PB_DEPRECATION, JavaCore.ERROR);
   
   // Set the new options
   JavaCore.setOptions(options);

Project specific options

The values of options can be overridden per project using protocol in IJavaProject.

The following code fragment retrieves the value of an option (COMPILER_PB_DEPRECATION) for a specific project in two different ways.  The boolean parameter controls whether only the project-specific options should be returned in a query or whether the project's option values should be merged with the values in JavaCore.


   // Get the project
   IJavaProject project = ...;

   // See if the value of an option has been set in this project
   String value = project.getOption(JavaCore.COMPILER_PB_DEPRECATION, false);
   if (value == null) {
     // no specific option was set on the project
     ...
   }
   
   // Get the value of an option from this project.  Use the value from 
   // JavaCore value if none is specified for the project
   String value = project.getOption(JavaCore.COMPILER_PB_DEPRECATION, true);

Compiler options

Description Values
Annotation Based Null Analysis (COMPILER_ANNOTATION_NULL_ANALYSIS)
This option controls whether the compiler will use null annotations for improved analysis of (potential) null references.

When enabled, the compiler will interpret the annotation types defined using COMPILER_NONNULL_ANNOTATION_NAME and COMPILER_NULLABLE_ANNOTATION_NAME as specifying whether or not a given type includes the value null.

The effect of these analyses is further controlled by the options COMPILER_PB_NULL_SPECIFICATION_VIOLATION, COMPILER_PB_NULL_ANNOTATION_INFERENCE_CONFLICT, COMPILER_PB_NULL_UNCHECKED_CONVERSION, COMPILER_PB_REDUNDANT_NULL_ANNOTATION, COMPILER_PB_MISSING_NONNULL_BY_DEFAULT_ANNOTATION, COMPILER_PB_SYNTACTIC_NULL_ANALYSIS_FOR_FIELDS, COMPILER_PB_NONNULL_PARAMETER_ANNOTATION_DROPPED, and COMPILER_INHERIT_NULL_ANNOTATIONS.

ENABLED
DISABLED
Inline JSR Bytecode Instruction (COMPILER_CODEGEN_INLINE_JSR_BYTECODE)
When enabled in conjunction with a Java target platform lesser than or equal to "1.4", the compiler will no longer generate JSR instructions, but rather inline corresponding subroutine code sequences (mostly corresponding to try finally blocks). The generated code will thus get bigger, but will load faster on virtual machines since the verification process is then much simpler. This mode is adding support for the Java Specification Request 202 to pre-"1.5" Java target platforms.
For a Java target platform greater than or equal to "1.5", the inlining of the JSR bytecode instruction is mandatory and this option is ignored.
ENABLED
DISABLED
Generating Method Parameters Attribute (COMPILER_CODEGEN_METHOD_PARAMETERS_ATTR)
When generated, this attribute will enable information about the formal parameters of a method (such as their names) to be accessed from reflection libraries, annotation processing, code weaving, and in the debugger, from platform target level 1.8 and later. GENERATE
DO_NOT_GENERATE
Setting Target Java Platform (COMPILER_CODEGEN_TARGET_PLATFORM)
For binary compatibility reason, .class files are tagged with VM versions that are defined for each level of the reference specification. The target Java platform specifies the minimum runtime level required to execute the generated class files.
The compliance, source and target levels must satisfy a set of constraints summarized in a compatibility table below.
VERSION_1_1
VERSION_1_2
VERSION_1_3
VERSION_1_4
VERSION_1_5
VERSION_1_6
VERSION_1_7
VERSION_1_8
VERSION_CLDC_1_1
Preserving Unused Local Variables (COMPILER_CODEGEN_UNUSED_LOCAL)
Unless requested to preserve unused local variables (i.e. never read), the compiler will optimize them out, potentially altering debugging. PRESERVE
OPTIMIZE_OUT
Setting Compliance Level (COMPILER_COMPLIANCE)
Select the compliance level for the compiler, which will then behave according to the said level of the reference specification.
The compliance, source and target levels must satisfy a set of constraints summarized in a compatibility table below.
VERSION_1_3
VERSION_1_4
VERSION_1_5
VERSION_1_6
VERSION_1_7
VERSION_1_8
Javadoc Comment Support (COMPILER_DOC_COMMENT_SUPPORT)
When this support is disabled, the compiler will ignore all javadoc problems options settings and will not report any javadoc problem. It will also not find any reference in javadoc comment and DOM AST Javadoc node will be only a flat text instead of having structured tag elements. ENABLED
DISABLED
Inheritance of Null Annotations (COMPILER_INHERIT_NULL_ANNOTATIONS)
When enabled, the compiler will check for each method without any explicit null annotations (see COMPILER_ANNOTATION_NULL_ANALYSIS): If it overrides a method which has null annotations, it will treat the current method as if it had the same annotations as the overridden method.

Annotation inheritance will use the effective nullness of the overridden method after transitively applying inheritance and after applying any default nullness (see COMPILER_NONNULL_BY_DEFAULT_ANNOTATION_NAME) at the site of the overridden method.

If different implicit null annotations (from a nonnull default and/or overridden methods) are applicable to the same type in a method signature, this is flagged as an error and an explicit null annotation must be used to disambiguate.

When generated, this attribute will enable local variable names to be displayed in the debugger, only in places where variables are definitely assigned (.class file is then bigger). GENERATE
DO_NOT_GENERATE
Name of Annotation Type for Non-Null Types (COMPILER_NONNULL_ANNOTATION_NAME)
This option defines a fully qualified Java type name that the compiler may use to perform special null analysis.

If the annotation specified by this option is applied to a type in a method signature or variable declaration, this will be interpreted as a specification that null is not a legal value in that position. Currently supported positions are: method parameters, method return type and local variables.

For values declared with this annotation, the compiler will never trigger a null reference diagnostic (as controlled by COMPILER_PB_POTENTIAL_NULL_REFERENCE and COMPILER_PB_NULL_REFERENCE), because the assumption is made that null will never occur at runtime in these positions.

The compiler may furthermore check adherence to the null specification as further controlled by COMPILER_PB_NULL_SPECIFICATION_VIOLATION, COMPILER_PB_NULL_ANNOTATION_INFERENCE_CONFLICT and COMPILER_PB_NULL_UNCHECKED_CONVERSION.

This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

The qualified name of a Java annotation type
Default is: org.eclipse.jdt.annotation.NonNull
Names of Secondary Annotation Types for Non-Null Types (COMPILER_NONNULL_ANNOTATION_SECONDARY_NAMES)
This option defines a comma-separated list of fully qualified Java type names that the compiler may use to perform special null analysis.

The annotation types identified by the names in this list are interpreted in the same way as the annotation identified by {@link #COMPILER_NONNULL_ANNOTATION_NAME}. The intention is to support libraries using different sets of null annotations, in addition to those used by the current project. Secondary null annotations should not be used in the project's own source code.

JDT will never actively use any secondary annotation names from this list, i.e., inferred null annotations and content assist proposals mentioning null annotations are always rendered using the primary name from COMPILER_NONNULL_ANNOTATION_NAME.

This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

The qualified name of a Java annotation type
Default is: ""
Name of Annotation Type for Nullable Types (COMPILER_NULLABLE_ANNOTATION_NAME)
This option defines a fully qualified Java type name that the compiler may use to perform special null analysis.

If the annotation specified by this option is applied to a type in a method signature or variable declaration, this will be interpreted as a specification that null is a legal value in that position. Currently supported positions are: method parameters, method return type and local variables.

If a value whose type is annotated with this annotation is dereferenced without checking for null, the compiler will trigger a diagnostic as further controlled by COMPILER_PB_POTENTIAL_NULL_REFERENCE.

The compiler may furthermore check adherence to the null specification as further controlled by COMPILER_PB_NULL_SPECIFICATION_VIOLATION, COMPILER_PB_NULL_ANNOTATION_INFERENCE_CONFLICT and COMPILER_PB_NULL_UNCHECKED_CONVERSION.

This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

The qualified name of a Java annotation type
Default is: org.eclipse.jdt.annotation.Nullable
Names of Secondary Annotation Types for Nullable Types (COMPILER_NULLABLE_ANNOTATION_SECONDARY_NAMES)
This option defines a comma-separated list of fully qualified Java type names that the compiler may use to perform special null analysis.

The annotation types identified by the names in this list are interpreted in the same way as the annotation identified by COMPILER_NULLABLE_ANNOTATION_NAME. The intention is to support libraries using different sets of null annotations, in addition to those used by the current project. Secondary null annotations should not be used in the project's own source code.

JDT will never actively use any secondary annotation names from this list, i.e., inferred null annotations and content assist proposals mentioning null annotations are always rendered using the primary name from COMPILER_NULLABLE_ANNOTATION_NAME.

This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

The qualified name of a Java annotation type
Default is: ""
Name of Annotation Type to specify a nullness default for unannotated types. (COMPILER_NONNULL_BY_DEFAULT_ANNOTATION_NAME)
This option defines a fully qualified Java type name that the compiler may use to perform special null analysis.

If the annotation is applied without an argument, all unannotated types in method signatures within the annotated element will be treated as if they were specified with the non-null annotation (see COMPILER_NONNULL_ANNOTATION_NAME).

If the annotation is applied with the constant false as its argument, all corresponding defaults specified using this annotation at outer scopes will be canceled for the annotated element.

This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

The qualified name of a Java annotatin type
Default is: org.eclipse.jdt.annotation.NonNullByDefault
Names of Secondary Annotation Types to specify a nullness default for unannotated types (COMPILER_NONNULL_BY_DEFAULT_ANNOTATION_SECONDARY_NAMES)
This option defines a comma-separated list of fully qualified Java type names that the compiler may use to perform special null analysis.

The annotation types identified by the names in this list are interpreted in the same way as the annotation identified by COMPILER_NONNULL_BY_DEFAULT_ANNOTATION_NAME. The intention is to support libraries using different sets of null annotations, in addition to those used by the current project. Secondary null annotations should not be used in the project's own source code.

  • For the given invocation this type variable is substituted with a nonnull type.
  • The type declaring the method is provided by a third-party library.
  • No null annotations exist for this library type, neither in its class file nor using external annotations.

This particular situation leverages the option to consistently substitute all occurrences of a type variable with a nonnull type, but it bears the risk that the library type may not be aware of null annotations thus lacking a necessary @Nullable annotation for a particular occurrence of a type variable.

  1. A method declared with a nonnull annotation returns an expression for which insufficient nullness information is available for statically proving that no flow will pass a null value at runtime.
  2. An expression for which insufficient nullness information is available for statically proving that it will never evaluate to a null value at runtime is passed as an argument in a method call where the corresponding parameter of the called method is declared with a nonnull annotation.
  3. An expression for which insufficient nullness information is available for statically proving that it will never evaluate to a null value at runtime is assigned to a local variable that is declared with a nonnull annotation.
Unchecked null conversion is usually a consequence of using other unannotated variables or methods.

The compiler options COMPILER_NONNULL_ANNOTATION_NAME and COMPILER_NULLABLE_ANNOTATION_NAME control which annotations the compiler shall interpret as nonnull or nullable annotations, respectively.

This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

Reporting problems detected by pessimistic null analysis for free type variables (COMPILER_PB_PESSIMISTIC_NULL_ANALYSIS_FOR_FREE_TYPE_VARIABLES)
Unless set to "ignore", type variables not affected by any explicit null annotation are pessimistically analyzed in two directions: When reading a value of this type, it is assumed to be nullable. When this type appears as the required type (i.e., at the left hand side of an assignment or variable initialization, or as the method return type against which a return statement is being checked) the type is considered to require the nonnull property.

Problems reported due to this pessimistic analysis are reported with the level given in this option.

  1. A method declared with a nonnull annotation returns a nullable expression.
  2. A nullable expression is passed as an argument in a method call where the corresponding parameter of the called method is declared with a nonnull annotation.
  3. A nullable expression is assigned to a local variable that is declared with a nonnull annotation.
  4. A method that overrides an inherited method declared with a nonnull annotation tries to relax that contract by specifying a nullable annotation (prohibition of contravariant return).
  5. A method that overrides an inherited method which has a nullable declaration for at least one of its parameters, tries to tighten that null contract by specifying a nonnull annotation for its corresponding parameter (prohibition of covariant parameters).

In the above an expression is considered as nullable if either it is statically known to evaluate to the value null, or if it is declared with a nullable annotation.

The compiler options COMPILER_NONNULL_ANNOTATION_NAME and COMPILER_NULLABLE_ANNOTATION_NAME control which annotations the compiler shall interpret as nonnull or nullable annotations, respectively.

In parallel with the Automatic Task Tags, this list defines the priorities (high, normal or low) of the task markers issued by the compiler.
Possible priorities are "HIGH", "NORMAL" or "LOW".

Default value is "NORMAL,HIGH,

Define the Automatic Task Tags (COMPILER_TASK_TAGS)
When the tag list is not empty, the compiler will issue a task marker whenever it encounters one of the corresponding tags inside any comment in Java source code. Generated task messages will start with the tag, and range until the next line separator, comment ending, or tag.
When a given line of code bears multiple tags, each tag will be reported separately. Moreover, a tag immediately followed by another tag will be reported using the contents of the next non-empty tag of the line, if any.
Note that tasks messages are trimmed. If a tag is starting with a letter or digit, then it cannot be leaded by another letter or digit to be recognized ("fooToDo" will not be recognized as a task for tag "ToDo", but "foo#ToDo" will be detected for either tag "ToDo" or "#ToDo"). Respectively, a tag ending with a letter or digit cannot be followed by a letter or digit to be recognized ("ToDofoo" will not be recognized as a task for tag "ToDo", but "ToDo:foo" will be detected either for tag "ToDo" or "ToDo:").
{<tag>[,<tag>]*}.
Default value is "TODO,FIXME,
