      Overrides:
        `getSource` in class `SourceTask`
      Returns:
        The source.

    - #### getToolChain

          @Inject
          public JavaToolChain getToolChain()

      Returns the tool chain that will be used to compile the Java source.
      Returns:
        The tool chain.

    - #### setToolChain

          @Incubating
          public void setToolChain(JavaToolChain toolChain)

      Sets the tool chain that should be used to compile the Java source.
      Parameters:
        `toolChain` - The tool chain.

          @Inject
          protected org.gradle.cache.CacheRepository getCacheRepository()

    - #### compile

          protected void compile()

      Specified by:
        `compile` in class `AbstractCompile`

    - #### getAntBuilderFactory

          @Inject
          protected org.gradle.internal.Factory<AntBuilder> getAntBuilderFactory()

    - #### getPlatform

          protected JavaPlatform getPlatform()

    - #### getDependencyCacheDir

          @Internal
          @Deprecated
          public File getDependencyCacheDir()

      Deprecated.

    - #### setDependencyCacheDir

          @Deprecated
          public void setDependencyCacheDir(File dependencyCacheDir)

      Deprecated.

    - #### getOptions

          public CompileOptions getOptions()

      Returns the compilation options.
      Returns:
        The compilation options.

    - #### getClasspath

          @CompileClasspath
          public FileCollection getClasspath()

      Description copied from class: `AbstractCompile`
      Returns the classpath to use to compile the source files.
      Overrides:
        `getClasspath` in class `AbstractCompile`
      Returns:
        The classpath.

    - #### getEffectiveAnnotationProcessorPath

          @Incubating
          @Classpath
          public FileCollection getEffectiveAnnotationProcessorPath()

      Returns the path to use for annotation processor discovery. Returns an empty collection when no processing should be performed, for example when no annotation processors are present in the compile classpath or annotation processing has been disabled.

      You can specify this path using `CompileOptions.setAnnotationProcessorPath(FileCollection)` or `CompileOptions.setCompilerArgs(java.util.List)`. When not explicitly set using one of the methods on `CompileOptions`, the compile classpath will be used when there are annotation processors present in the compile classpath. Otherwise this path will be empty.

      This path is always empty when annotation processing is disabled.
