- - ### Method Detail

    - #### public CompileOptions debug(Map<String, Object> debugArgs)

      Convenience method to set DebugOptions with named parameter syntax. Calling this method will set `debug` to `true`.

    - #### public CompileOptions depend(Map<String, Object> dependArgs)

      Convenience method to set DependOptions with named parameter syntax. Calling this method will set `useDepend` to `true`.

    - #### @Override protected boolean excludeFromAntProperties(String fieldName)

    - #### public CompileOptions fork(Map<String, Object> forkArgs)

      Convenience method to set ForkOptions with named parameter syntax. Calling this method will set `fork` to `true`.

    - #### @Override protected String getAntPropertyName(String fieldName)

    - #### @Override protected Object getAntPropertyValue(String fieldName, Object value)

    - #### @Input @Optional public String getBootClasspath()

      Returns the bootstrap classpath to be used for the compiler process. Defaults to `null`.

    - #### @Input public List<String> getCompilerArgs()

      Returns any additional arguments to be passed to the compiler. Defaults to the empty list.

    - #### @Nested public DebugOptions getDebugOptions()

      Returns options for generating debugging information.

    - #### public DependOptions getDependOptions()

      Returns options for using the Ant `<depend>` task.

    - #### @Input @Optional public String getEncoding()

      Returns the character encoding to be used when reading source files. Defaults to `null`, in which case the platform default encoding will be used.

    - #### @Input @Optional public String getExtensionDirs()

      Returns the extension dirs to be used for the compiler process. Defaults to `null`.

    - #### @Nested public ForkOptions getForkOptions()

      Returns options for running the compiler in a child process.

    - #### @Input @Optional @Incubating public FileCollection getSourcepath()

      The source path to use for the compilation.

      The source path indicates the location of source files that may be compiled if necessary. It is effectively a complement to the class path, where the classes to be compiled against are in source form. It does not indicate the actual primary source being compiled.

      The source path feature of the Java compiler is rarely needed for modern builds that use dependency management.

      The default value for the source path is `null`, which indicates an empty source path. Note that this is different to the default value for the `-sourcepath` option for `javac`, which is to use the value specified by `-classpath`. If you wish to use any source path, it must be explicitly set.

      Returns:
        the source path
      See Also:
        setSourcepath(FileCollection)

    - #### @Input public boolean isDebug()

      Tells whether to fail the build when compilation fails. Defaults to `true`.
