## Class Javadoc

- java.lang.Object
- - org.apache.tools.ant.ProjectComponent
  - - org.apache.tools.ant.Task
    - - org.apache.tools.ant.taskdefs.Javadoc

- All Implemented Interfaces:
    java.lang.Cloneable

      public class Javadoc
      extends Task

  Generates Javadoc documentation for a collection of source code.

  Current known limitations are:

  - patterns must be of the form "xxx.*", every other pattern doesn't work.
  - there is no control on arguments sanity since they are left to the Javadoc implementation.

  If no `doclet` is set, then the `version` and `author` are by default `"yes"`.

  Note: This task is run on another VM because the Javadoc code calls `System.exit()` which would break Ant functionality.

  Since:
    Ant 1.1
