How to import exported packages from an own plugin? [message #649083]

Hello all,

currently I want to make exported packages of my plugin available for any kind of project. Regardless if it is a simple java project or plugin project or something else.
If I have a plugin project I just make it dependent on my own plugin (with the exported package) and I can use the exported package with "import my.package;".
Once I want to do the same (import my.package) in a simple java workspace project, my only idea to make this work is to add the jar of the plugin to the build path. Otherwise I havn't found a way to do so.
So my questions are: Is this the only way to do so? and: Is my general approach of having a plugin which publishes packages appropriate for this task?

Thanks and bye

Tom,

Why not make everything be plug-in projects? Such projects can still be
used to produce a jar that runs on a normal classpath. That's what we
do wtih EMF.

Hi Ed,

that's surely a way to do so. And I think I already chummed up with it Smile

In the end it's just an advice on how to use my plugin.

Maybe my thought just came up with a try to make everything as simple as possible. But using plugins everytime is a compromise I can live with Smile

Thanks for your answer, Ed and good bye

It doesn't work that way; ordinary workspace Java projects can't depend
on installed plug-ins. You can depend on plug-in code if the plugin is
loaded as a workspace project (as opposed to being installed into the
running Eclipse instance), but I don't think that's what you're talking
about.

It's possible to write a plugin that modifies workspace projects to add
things to their build path; perhaps that what you want?
