  - ### getExecutable

    @Optional @Input public @Nullable String getExecutable()
    Returns the compiler executable to be used.

    Only takes effect if `CompileOptions.fork` is `true`. Defaults to `null`.

    Setting the executable disables task output caching.

    Since:
      0.7

  - ### setExecutable

    public void setExecutable(@Nullable String executable)
    Sets the compiler executable to be used.

    Only takes effect if `CompileOptions.fork` is `true`. Defaults to `null`.

    Setting the executable disables task output caching.

    Since:
      0.7

  - ### getJavaHome

    @Internal public @Nullable File getJavaHome()
    Returns the Java home which contains the compiler to use.

    Only takes effect if `CompileOptions.fork` is `true`. Defaults to `null`.

    Since:
      3.5

  - ### setJavaHome

    public void setJavaHome(@Nullable File javaHome)
    Sets the Java home which contains the compiler to use.

    Only takes effect if `CompileOptions.fork` is `true`. Defaults to `null`.

    Since:
      3.5

  - ### getTempDir

    @Internal public @Nullable String getTempDir()
    Returns the directory used for temporary files that may be created to pass command line arguments to the compiler process. Defaults to `null`, in which case the directory will be chosen automatically.
    Since:
      0.7

  - ### setTempDir

    public void setTempDir(@Nullable String tempDir)
    Sets the directory used for temporary files that may be created to pass command line arguments to the compiler process. Defaults to `null`, in which case the directory will be chosen automatically.
