How to dynamically update the classpath [message #329285]

Hello

Does anyone knows how to dynamically update the classpath of a project ?
We have a plug-in, and when we select an action of this plugin, we want
the classpath project to be updated.
We tried by modifying the classpath file, but it seems that the
modification is not taken into account.
Any help on either the classpath modification or our refresh problem would
be appreciated

Regards

CG

You'd use the IJavaProject.SetRawClasspath() method.

Be careful: you have to get the classpath, add your entry, and then set it,
so if two threads try to do that at the same time, one will be silently
ignored :-(
