Made a plugin using Eclipse Java (in Windows).
Tested and Exported the plugin.
Imported the plugin in Eclipse CDT (in Linux).
Get the following exception:
Caused by: java.lang.ClassNotFoundException: com.myUI cannot be found by myJar_1.0.0.201708011131
Any idea as to why? I have been researching this for some time and have tried many many "solutions".
Please advise.

In Eclipse I have for some reason since last week a weird error while using Groovy. I never seen this error before and a search shows that I seems to be the only one.

I have no clue why I get this. I'm not using Swing or Groovy Swing anywhere. It's not JUnit 5 related because I got this also from Guice.
This should be related with Eclipse because if I compile it in Maven it runs fine. Currently I need to do a mvn clean install so that it runs again in Eclipse.
Eclipse Version: 2022-06 (4.24.0)
Build id: 20220609-1112
Groovy 3.0.14
Run in Eclipse. Groovy is added as dependency. It should run without errors.
I am developing a JEE project using Eclipse JEE (2019-09), Maven, Wildfly 17, JSF, PrimeFaces 7.0 running on Ubuntu 18.04.
My project used to compile, deploy and run on the WildFly 17 server until today. However, because I recieved strange errors when debugging, I installed an earlier Eclipse IDE to try to run my project on it.
After installing the older version of Eclipse (2019-03) in its own dedicated workspace, I got this error message when deploying my application to WildFly:
Caused by: java.lang.RuntimeException: WFLYSRV0177: Error getting reflective information for class
I then switched back to my initial Eclipse JEE (2019-09) Version, but then I kept recieving the same error message upon deploying.
I' ve searched the internet and found these two similar problems:
Error getting reflective information for class
Wildfly: Error getting reflective information for class
but actually not a solution to my problem.
Could somebody please help?
The problem was that the Maven jar- dependencies were not added to the WEB-INF/lib path.
Actually, in the deployed .war file the folder WEB-INF/lib was completely missing.
I fixed the problem by right-mouse click on my project in Eclipse, then "Properties", then "Deployment Assembly".
I added the missing entry "Maven Dependencies" as follows:
1.) BEFORE MY FIX:
2.) AFTER MY FIX:
After trying to install the oxygen IDE, Eclipse has simply stopped working altogether. I had the Neon binaries in one folder and decided to install Oxygen in another directory. Now neither program will start! I am using Linux Mint.
I have checked
Eclipse wont run: \.metadata\.log error
but it doesn't apply to my situation; changing the workspace doesn't solve my problem.
I am simply given the message "An error has occurred. See the log file" and that is all.
The content of the log file can be found here:

Basically, it repeats messages of the form

I have tried reinstalling Java, but this doesn't help either.
I'm using Eclipse Neon from the release date. Yesterday I got some strange errors in Eclipse and after a reboot of the Eclipse instance everything was gone. I installed Eclipse and my plugins again. Everything is working again but when I launch the Java debugger on one of my project I got the error:
An internal error occurred during: "XXXX".
java.lang.NullPointerException
This error occurs on debugging all my projects also in another workspace. Can someone help me with this? The error is not explaining what the exact problem is.
In the logfile of Eclipse I can found the follow error:
java.lang.NullPointerException

I fully removed my previous Eclipse environment. Settings included.
Installed Eclipse environment from a clean install and installed all my plugins again. The problem was fixed.
I am getting this error java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()
at the runtime in eclipse. However, eclipse shows the method on doing intelligence search, but at runtime it fails to identify it.
I am using the latest log4j1.2.16 jar and it is added in the classpath.
Any suggestions?
