Class JavaRuntime


  • public final class JavaRuntime
    extends Object
    The central access point for launching support. This class manages the registered VM types contributed through the "org.eclipse.jdt.launching.vmType" extension point. As well, this class provides VM install change notification, and computes class paths and source lookup paths for launch configurations.

    This class provides static methods only.

    Restriction:
    This class is not intended to be instantiated by clients.

      • JRE_CONTAINER

        public static final String JRE_CONTAINER
        Classpath container used for a project's JRE (value "org.eclipse.jdt.launching.JRE_CONTAINER"). A container is resolved in the context of a specific Java project, to one or more system libraries contained in a JRE. The container can have zero or two path segments following the container name. When no segments follow the container name, the workspace default JRE is used to build a project. Otherwise the segments identify a specific JRE used to build a project:
        1. VM Install Type Identifier - identifies the type of JRE used to build the project. For example, the standard VM.
        2. VM Install Name - a user defined name that identifies that a specific VM of the above kind. For example, IBM 1.3.1. This information is shared in a projects classpath file, so teams must agree on JRE naming conventions.

        Since 3.2, the path may also identify an execution environment as follows:

        1. Execution environment extension point name (value executionEnvironments)
        2. Identifier of a contributed execution environment

      • ERR_UNABLE_TO_RESOLVE_JRE

        public static final int ERR_UNABLE_TO_RESOLVE_JRE
        A status code indicating that a JRE could not be resolved for a project. When a JRE cannot be resolved for a project by this plug-in's container initializer, an exception is thrown with this status code. A status handler may be registered for this status code. The source object provided to the status handler is the Java project for which the path could not be resolved. The status handler must return an IVMInstall or null. The container resolver will re-set the project's classpath if required.

        Attribute key for a process property. The class org.eclipse.debug.core.model.IProcess allows attaching String properties to processes. The value of this attribute is the command line a process was launched with. Implementers of IVMRunner should use this attribute key to attach the command lines to the processes they create.

        public static final String PREF_ONLY_INCLUDE_EXPORTED_CLASSPATH_ENTRIES

        Constant Field Values
      • CLASSPATH_ATTR_LIBRARY_PATH_ENTRY

        public static final String CLASSPATH_ATTR_LIBRARY_PATH_ENTRY
        Attribute key for a classpath attribute referencing a list of shared libraries that should appear on the -Djava.library.path system property.

        The factory methods newLibraryPathsAttribute(String[]) and getLibraryPaths(IClasspathAttribute) should be used to encode and decode the attribute value.

        Each string is used to create an IPath using the constructor Path(String), and may contain IStringVariable's. Variable substitution is performed on the string prior to constructing a path from the string. If the resulting IPath is a relative path, it is interpreted as relative to the workspace location. If the path is absolute, it is interpreted as an absolute path in the local file system.

                                                      throws CoreException
        Returns a runtime classpath entry identifying the JRE to use when launching the specified configuration or null if none is specified. The entry returned represents a either a classpath variable or classpath container that resolves to a JRE.

        The entry is resolved as follows:

        1. If the ATTR_JRE_CONTAINER_PATH is present, it is used to create a classpath container referring to a JRE.
        2. Next, if the ATTR_VM_INSTALL_TYPE and ATTR_VM_INSTALL_NAME attributes are present, they are used to create a classpath container.
        3. When none of the above attributes are specified, a default entry is created which refers to the JRE referenced by the build path of the configuration's associated Java project. This could be a classpath variable or classpath container.
        4. When there is no Java project associated with a configuration, the workspace default JRE is used to create a container path.

        Parameters:
        configuration - the backing ILaunchConfiguration
        Returns:
        classpath container path identifying a JRE or null
