Hi all,

i've a common question about how to recreate a plugin from an existing
jar. In my case, a new version of the has been released and i want to
replace the files of the existing plugin (from the old jar) with the
files of the new jar. Is this possible or may i have to create a
completly new plugin???

Thx for any help.
Timothy

Hi,
I would say that you have to recreate the entire plugin.
The reason is that plugin Manifest:Export-Package contains the list of the packages of the jars of the plugin.
Given that (probably) the packages of the new jar differ from those of the old jar such a list will not be valid and therefore you have to regenerate the entire plugin.

Hi,
hmm... this is not optimal, since the current plugin is imported into
svn, so i have to kill it and reimport it everytime, i want to update
the referenced library. I think this is a very tedious work, hm?

I have written a java tool that generates plugins out of jars. It is not very difficult when you know how an eclipse plugin is generated out of a set of jars.
