# Groovydoc

API Documentation: | `Groovydoc`

Generates HTML API documentation for Groovy source, and optionally, Java source.

This task uses Groovy's Groovydoc tool to generate the API documentation. Please note that the Groovydoc tool has some limitations at the moment. The version of the Groovydoc that is used, is the one from the Groovy dependency defined in the build script.

### Methods

Method | Description
`exclude(excludeSpec)` | Adds an exclude spec. This method may be called multiple times to append new specs.The given closure is passed a `FileTreeElement` as its parameter. The closure should return true or false. Example:
`exclude(excludes)` | Adds an ANT style exclude pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.
`exclude(excludes)` | Adds an ANT style exclude pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.
`exclude(excludeSpec)` | Adds an exclude spec. This method may be called multiple times to append new specs. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.
`include(includeSpec)` | Adds an include spec. This method may be called multiple times to append new specs. The given closure is passed a `FileTreeElement` as its parameter. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.
`include(includes)` | Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.
`include(includes)` | Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.
`include(includeSpec)` | Adds an include spec. This method may be called multiple times to append new specs. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.
`link(url, packages)` | Add links to groovydoc/javadoc output at the given URL.
`source(sources)` | Adds some source to this task. The given source objects will be evaluated as per `Project.files(java.lang.Object[])`.
