<h2 id="jarlib-manifest">jarlib-manifest</h2>
<h3>Description</h3>
<p>Task to generate a manifest that declares all the dependencies in manifest. The dependencies are
determined by looking in the specified path and searching for Extension / "Optional Package"
specifications in the manifests of the jars.</p>

<p>Note that this task works with extensions as defined by the "Optional Package" specification.
For more information about optional packages, see the document <em>Optional Package Versioning</em>
in the documentation bundle for your Java Standard Edition package, in
file <code>guide/extensions/versioning.html</code> or the
online <a href="https://docs.oracle.com/javase/8/docs/technotes/guides/extensions/versioning.html"
target="_top">Extension and ExtensionSet documentation</a> for further details.</p>
