Description

Default

Maximum number of reported problems per compilation unit

Specifies how many problems should be reported for a compilation unit.

100

Enable use of exclusion patterns in source folders

When disabled, no entry on a project classpath can be associated with an exclusion pattern.

On

Enable use of multiple output locations for source folders

When disabled, no entry on a project classpath can be associated with a specific output location, preventing thus usage of multiple output locations.

On

Build path problems

Abort build when build path errors occur

Allow to toggle the builder to abort if the classpath is invalid.

On

Incomplete build path

Indicate the severity of the problem reported when an entry on the classpath does not exist, is not legitimate or is not visible (e.g. a reference project is closed).

Error

Circular dependencies

Indicate the severity of the problem reported when a project is involved in a cycle.

Error

Incompatible required binaries

Indicate the severity of the problem reported when a project requires another project or library with an incompatible target JDK level (e.g. a project using 1.4 compiler compliance, but compiled against 1.5 system libraries on the build path).

Ignore

Output location overlaps source location

Indicated the severity of the problem reported when a source entry's output location overlaps another source entry.

Error

No strictly compatible JRE for execution environment available

Indicate the severity of the problem reported when project's build path contains an execution environment for which there is no strictly compatible JRE available in the workspace (e.g. a project using execution environment JavaSE-1.6 as JRE System Library, but the only Installed JREs available in the preferences are 1.7 and 1.8.

Ignore

Output folder

Duplicated resources

Indicate the severity of the problem reported when more than one occurrence of a resource is to be copied into the output location.

Warning

Scrub output folders when cleaning projects

Indicate whether the Java Builder is allowed to clean the output folders when performing full build operations.

On

Rebuild class files modified by others

Indicate whether class files which have been modified by others should be rebuilt to undo the modification.

Off

Filtered resources

A comma separated list of file patterns which are not copied to the output folder.
