Howto update Process Definitions to more recent GPD Versions

[becka]

We are currently using Eclipse 3.1.1 and GPD 3.0.5 and want to update to a more recent version.
But if i import our existing Projects f.e. in 3.0.6, i always get an error message and eclipse becomes unusable.
This happens even with a total simple process without any additional libs or source files

Please help!

[maxandersen]

sounds like a bug.

could you give some more information ?

like what error etc?

[becka]

After a Import, the Package explorer stays empty.
If i restart eclipse i get the error "An internal error occured during: Initializing Java tooling"

The Stacktrace:

EDIT: The Package Explorer shows the imported Project, but only the Project name, i cant expand it to work with the sources

The Stacktrace:

During simple tests i found, that it woks if you change the jbpm entry in clathpath to the one of the new version.

-> create new process project
-> open .classpath of this project
-> copy jbpm version

-> open existing project folder
-> open .classpath
-> change the jbpm version

-> import
-> have fun

[maxandersen]

ok, i would report this in our jira to let koen know about it.
