Eclipse failure during a maven update

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

Why won't Netbeans 9.0 show any error markers?

I recently had to install Netbeans 9.0 to work on a gradle project at work, but unfortunately the editor won't show any error markers as i write code. Compilation errors are shown once i run, but i don't visualize them in the editor, even with obvious errors like not closing up a class with }. I also have netbeans 8.0.2 that i've installed through the installer, and error markers are shown correctly there. Has anyone encountered this problem, or knows how to fix it?
If you are using Java, please install nb-javac plugin.
I had same problem with NetBeans 11.2. It resolved after I installed this plugin and restarted the IDE.

Unable to install PMD in Spring tool suite

I am unable to install PMD plug-in for STS (build on top of Luna).
Could someone please give the steps to do it?
Try this http://sourceforge.net/projects/pmd/files/pmd-eclipse/update-site/ and install for Eclipse 4.
I'm the developer of eclipse-pmd, one of the two PMD plugins you mentioned in your question. If your installing the plugin through the Eclipse Marketplace then you're doing everything right. Once the installation is finished the getting started guide will help you with setting up eclipse-pmd.
You are, however, not the first who has a problem getting eclipse-pmd 1.4 to work with the Spring Tool Suite. Unfortunately we have not yet found the cause of the problem and are still looking for a solution. If you'd like to help or would like to follow the issue's progress then head over to the eclipse-pmd issue tracker at Github.
Update: the issue has been fixed and it had nothing to do with STS.
If your problem is something different then I need more information on what exactly does not work, e.g. does the installation give you an error message or doesthe installation work and you get an error message when running PMD?
Please follow below steps to install PMD in STS.
Download PMD from https://sourceforge.net/projects/pmd-eclipse/files/ & Extract it.
Copy net.sourceforge.pmd.eclipse_1.8.0 folder into ..\sts-bundle\sts-3.9.6.RELEASE\plugins\
then Install eclipse PMD from Eclipse Market Place you will find in Help this option.
Restart your STS.

Failed to create javafx flatform in netbeans

I got this error when I'm trying to create a Java Swing Application, by using Netbeans.
I really don't know how to fix this error. Internet did't give me a really good answer.
I Unistalled Netbeans & then reInstalled. but It doesn't work.
How can I fix this error. Thank you.
I don't have a NetBeans installation at hand, but have a look at your Java installations configured in NetBeans ("Java Platform Manager" in Tools menu?). Select the Java version you are using. There should be a JavaFX tab. I think you can disable it there, if you don't need it.
Note: If you're using the latest Java version from Oracle, then JavaFX should automatically be configured correctly, since JavaFX is now shipped with the JDK.

eclipse plugins not visible

I have recently installed gwt-plugin to my eclipse. But plugins are are not visible, even if I try to install it again, eclipse is not allowing me to install, saying its already installed.I even I ran eclipse as administrator(I am using it in windows 7) and also with clean option, nothing worked out.
And one more thing, After GWT installation, it gave two options - 'Restart' and 'Apply changes'.I have chosen 'Restart'. (Does it matter?)
Any help is appreciated..
Maybe you installed gwt-plugin correctly, but you are missing one of its dependencies? Take a look at this thread. One of the answers discusses using the OSGI console to locate missing dependencies.
