/**
 * Options for the Ant Depend task. Only take effect if {@code CompileOptions.useAnt} and
 * {@code CompileOptions.useDepend} are {@code true}.
 *
 * <p>The Ant Depend task will delete out-of-date and dependent class files before compiling
 * so that only those files will be recompiled. This is not fool-proof but may result in faster compilation.
 * See the <a href="http://ant.apache.org/manual/Tasks/depend.html" target="_blank">Ant Reference</a>
 * for more information.
 *
 * <p>The {@code srcDir}, {@code destDir}, and {@code cache} properties of the Ant task
 * are set automatically. The latter is replaced by a {@code useCache} option to enable/disable caching of
 * dependency information.
