org.apache.tools.ant.Task
org.apache.tools.ant.taskdefs.optional.extension.JarLibManifestTask

All Implemented Interfaces:
  `Cloneable`

public final class JarLibManifestTask extends Task
Generates a manifest that declares all the dependencies. The dependencies are determined by looking in the specified path and searching for Extension / "Optional Package" specifications in the manifests of the jars.

Prior to JDK1.3, an "Optional Package" was known as an Extension. The specification for this mechanism is available in the JDK1.3 documentation in the directory $JDK_HOME/docs/guide/extensions/versioning.html. Alternatively it is available online at https://docs.oracle.com/javase/8/docs/technotes/guides/extensions/versioning.html.
