# Source Locations

###### Identifier:

org.eclipse.pde.core.source

###### Since:

2.0

###### Description:

This extension point allows PDE to find source archives for libraries in Eclipse plug-ins found in an Eclipse-based product. It is used to contribute locations that contain source archives. These locations are expected to contain the same layout as the 'plugins' directory.

For each plug-in or fragment, a directory in the form {id}_{version} should exist. The content of the directory corresponds to the plug-in/fragment location. It should contain source code zip file in the form {library name}src.zip where library name is the name of the Java library that matches the source code. For JAR'd plug-ins and libraries named '.', the source zip file must be named simply `src.zip`.

In addition, it should contain any file or directory specified in the build.properties using `src.includes` variable.

###### Configuration Markup:

<!ELEMENT extension (location+)>

<!ATTLIST extension

point CDATA #REQUIRED

id CDATA #IMPLIED

name CDATA #IMPLIED>

<!ELEMENT location EMPTY>

<!ATTLIST location

path CDATA #REQUIRED>

- path - the relative path of the directory in the contributing plug-in where source content is stored. The folder must contain one or more directories in the form {id}_{version} where `id` is a matching plug-in or fragment identifier and `version` is the matching plugin/fragment version. These directories in turn should contain source archives and any other file or folder specified using `src.includes` variable in build.properties file of the corresponding plug-in/fragment.

###### Examples:

The following is an example of the `source` extension:

     <extension point = "org.eclipse.pde.core.source">
         <location path="src"/>
      </extension>

In the example above, the source location `src` in the contributing plug-in has been registered.

###### API Information:

No Java code is required for this extension point.

###### Supplied Implementation:

Eclipse SDK comes with source plug-ins that contain source information for all the plug-ins and fragments in Eclipse SDK.
