Eclipse failure during a maven update

Question

First of all, probably my question is not well asked or is too easy or too simple but I'm a little bit novice and Vaadin and I can't figure what is happening.

When I try to update the maven project using "Update project" doing right client over "pom.xml", I get the following error over and over.

An internal error occurred during: "Updating Maven Project".
Receiver class com.baselet.plugin.MavenProjectChangedListener does not define or inherit an implementation of the resolved method 'abstract void mavenProjectChanged(java.util.List, org.eclipse.core.runtime.IProgressMonitor)' of interface org.eclipse.m2e.core.project.IMavenProjectChangedListener.

When I click "ok", the same error appears again and again.

I'm using:

• Eclipse 2022-12
• JDK Zulu 17
• Apache Maven 3.8.7 which I downloaded and I selected at Eclipse's configuration.

I tried several projects and it is always the same. Could someone give me an advise?

Regards,

The current UMLet plugin which you have installed does not work with the current Eclipse Maven integration (m2e) 2.x of Eclipse 2022-09 and higher containing m2e 2.x in contrast to previous Eclipse IDE releases.

Please make sure the issue has been reported to the UMLet project .

See also m2e issue #991 , closed as not a m2e issue with the following comment by Mickael Istria :

It looks like the com.baselet plugin is not compatible with m2e 2.x. Please report issue to that plugin
