All Implemented Interfaces:
  `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
