Plug-in Archives

Plug-ins and plug-in fragments are individually packaged as separate Java .jars. Standard Java jar facilities are used for constructing plug-in archives. There is no distinction made between a plug-in archive containing a plug-in and one containing a plug-in fragment.

The recommended convention for naming the plug-in archives is

Where <id> is the plug-in or fragment identifier and <version> is the full version identifier contained in the respective plugin.xml or fragment.xml. Note that this is a recommended convention that minimizes chance of collisions, but is not required by the Eclipse architecture. For example, the following are valid plug-in archive names:


Internally, each plug-in archive packages all the relevant plug-in or fragment files relative to its plug-in or fragment directory (but not including the directory path element). The archive has the following structure

plugin.xml *OR* fragment.xml
other plug-in or fragment files and subdirectories
    Java jar manifest and security files
