Error in Eclipse 2024-03

Flowable Designer
1

Hi Team,

I have installed the Flowable designer in Eclipse 2024-03. I was able to create a new Flowable project, but when I tried to create a new BPMN diagram, I got the following error: class org.eclipse.jdt.internal.core.JavaNature cannot be cast to class org.eclipse.jdt.core.IJavaProject (org.eclipse.jdt.internal.core.JavaNature and org.eclipse.jdt.core.IJavaProject are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @2f476789)

I installed the Eclipse version for diagram-based application development which included ecore and Java Development Tools.

Any guidance would be appreciated :slight_smile:

Thanks!

Since that time I started to work with the intelij plugin:

There were some issues to get it running on community edition and latest version, but they were resolved in:

so now I am able to run and fix issues in the plugin.

I’ve created a fix for eclipse if anyone has the power to review/merge:

Exception in thread "main" java.lang.NoSuchMethodError: 'java.lang.String org.eclipse.equinox.p2.core.IProvisioningAgent.getProperty(java.lang.String)'
