org.eclipse.core.runtime.CoreException: The class file is not on the classpath

from the beginning, while trying to deploy a war under Jetty, I have an error, and in order to understand from where the error is comming, I would like to put a breakpoint in a class (SimpleCDI) located in a dependency (a jar which is downloaded by MAVEN). I work under MAC and when I hit Command + Shift + T and look up "SimpleCDI" class, it points that the class is within org.jboss.weld package

Here is a printscreen of my research enter image description here

And when I click on the "C SimpleCDI org.jboss.weld" line, it returns an error message

org.eclipse.core.runtime.CoreException: The class file is not on the classpath

    at org.eclipse.ui.texteditor.AbstractTextEditor.internalInit(AbstractTextEditor.java:3172)

I checked that I have the right dependency (weld-servlet-2.4.5.Final.jar) with SimpleCDI" in it.

I noticed that the eclipse icon of my dependency "weld-servlet-2.4.5.Final.jar" is the following enter image description here

It is a jar file without attached source. Actually, I can see this dependency in Eclipse in one of my module "Tourism-Services" (I have a Maven multi module project) in the "Referenced Librairies" folder with the icon mentioned above, but the Maven dependency that import this jar is located in another module "Tourism-Core" which is imported itself in "Tourism-Services" module. I notice in passing that I cannot see "weld-servlet-2.4.5.Final.jar" in "Referenced Librairies" folder of "Tourism-Core" module (why ?)

My main question is : why cannot I edit "SimpleCDI" class and put a breakpoint in order to debug upstream

I've also been using the CodeMix plugin, have you tried to remove the Open Type binding from the CodeMix preferences? Preferences -> Codemix -> Bindings. From there uncheck the "Open Types on COMMAND+SHIFT+T" and do apply and close. This will get you to use the regular Open Java Type from Eclipse.

Cheers

a plugin was causing the error. It is CodeMix plugin

I tried to uninstall it : help->Eclipse Marketplace->Installed I obtain the following screen

enter image description here

I chose uninstall in the dropDown

But it doesn't work.

I have found a workaround : https://www.genuitec.com/forums/topic/uninstall-codemix/

But it is temporary. I tried to find CodeMix in Eclipse plugin folder (I work under MAC), but there is nothing. Do you see another way ?
