For an Eclipse plugin, I need to refer to a jar file inside the plugin directory (to provide code to users). This works perfectly when running the plugin while developing (inside a runtime-eclipse-application).
But when I build an update site, my plugin is built into a jar file. File paths for images are still working, but when the jar should be imported, eclipse shows the following error:
Description Resource Path Location Type
The container 'DoodleDebug' references non existing library 'file:\C:\Users\Me\.eclipse\org.eclipse.platform_3.7.0_740800064\plugins\ch.unibe.scg.doodledebug_1.0.0.201208281642.jar!\DoodleDebug-Client.jar'
The outer jar path is correct and when inspecting it with WinRAR, I can see the desired jar file inside it!
Why isn’t this working as expected?
You will need to install your plugin in an exploded form. To do this, in your MANIFEST.MF file, add the following line:
This will ensure that your plugin is installed as a directory, not a jar file. There is no way to reference nested jars, so they must be exploded.
