      • setIncremental

        public CompileOptions setIncremental​(boolean incremental)
        Configure the java compilation to be incremental (e.g. compiles only those java classes that were changed or that are dependencies to the changed classes).

      • getIncrementalAfterFailure

        @Input
@Optional
@Incubating
public Property<java.lang.Boolean> getIncrementalAfterFailure()
        Used to enable or disable incremental compilation after a failure.

        By default, incremental compilation after a failure is enabled for Java and Groovy. It has no effect for Scala. It has no effect if incremental compilation is not enabled.

        When the Java command line compiler is used, i.e. when a custom java home is passed to forkOptions.javaHome or javac is passed to forkOptions.executable, this optimization is automatically disabled, since the compiler is not invoked via the compiler API.

      • getSourcepath

        @Optional
@Nullable
@IgnoreEmptyDirectories
@PathSensitive(RELATIVE)
@InputFiles
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)

      • setSourcepath

        public void setSourcepath​(@Nullable
                          FileCollection sourcepath)

        Parameters:
        sourcepath - the source path

      • getAnnotationProcessorPath

        @Nullable
@Optional
@Classpath
public FileCollection getAnnotationProcessorPath()
        Returns the classpath to use to load annotation processors. This path is also used for annotation processor discovery.
        Returns:
        The annotation processor path, or null if annotation processing is disabled.
        Since:
        3.4

      • setAnnotationProcessorPath

        public void setAnnotationProcessorPath​(@Nullable
                                       FileCollection annotationProcessorPath)
        Set the classpath to use to load annotation processors. This path is also used for annotation processor discovery.
