I’m getting the “No STRJ InteropRegisterer classes found in JAR files” issue on my home Mac, after checking out a project that was working OK on my Mac at the office. Using a fresh instance of the nightly release didn’t help. A similar issue reported on Windows is still open.

To reproduce the issue, I do:

• check out CBSEditor from SVN as a Maven project;
• build CBSEditor;
• check out IMPEditor from SVN as a Maven project;
• open any *.cbs file in IMPEditor.

I get a red flag in the buffer saying “failed to update editor” and the following in the console:

Before, the cbs files would parse and analyse OK. I haven’t changed the syntax or name analysis of the CBS language recently.

Try a Maven update on the projects (right click projects -> Maven -> Update Project…), then rebuild them.

Updating (with the option “Force Update of Snapshots/Releases” ticked) appears to have fixed the issue: both projects now build successfully again, and my cbs files parse and analyse without any errors. Many thanks for the accurate diagnosis!
