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?

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:

How can I fix it?
Add TestNG Library to classpath in buildpath ( not to module path). It will work fine.
To avoid this error, do not add TestNG library in the project or src folder. Try adding it into the package. To do so , follow the below mentioned procedure.
Right click on the package, click Build Path->Configure Build Path, go to Libraries tab, select Classpath and click on Add Library to select TestNG.
This error message...

...implies that there was an issue with the java classpath.
As per the discussion Launch with java 11 fails: Error: Could not find or load main class with Caused by: java.lang.ClassNotFoundException: with there are some issues with some particular classpaths for java-11 and the launch fails if:
The classpath contains a folder with spaces
The classpath length is larger than 32767 characters.
Where as java-8 works fine.

Eclipse plugin: TestNG testcase does not run with Jdk11
Need to add 1.8 version library
Remove TestNG from build path library and add again
Recheck - the issue should be resolved.
I got same issue and I solved it. When creating the project, don't create module-info.java. When the project was already created with the module-info.java, deleting this file didn't help me.
I just created new project without module-info.java, and all works good now.
Best option to resolve this:
Find all file and folder starting with . e.g. — .metadata / .setting and delete them.
Add all the JARS.
Add testNG Libraries.
Execute it.
Done.
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.
I am using the newest version (2.8.0) of the Eclipse-Groovy plugin that ships with groovy-all-2.1.5.jar. I added Guice to my Groovy project, and when I go to run them from inside Eclipse I get the following error in the console output:

According to this answer it's because ShortTypeHandling wasn't added until 2.3.x. So I would now like to attach groovy-all-2.3.3.jar to my Eclipse project's classpath.
The problem is that I don't seem to have edit permissions to change what library the Groovy Libraries library uses under the hood. And when I manually add the 2.3.3 JAR to my build path, I get the following error:
Caught: java.lang.ExceptionInInitializerError
java.lang.ExceptionInInitializerError
Caused by: groovy.lang.GroovyRuntimeException: Conflicting module versions. Module [groovy-all is loaded in version 2.1.5 and you are trying to load version 2.3.3
What are my options?
Groovy-eclipse versions have its own compilers and are "locked" to them. You may change the versions to whatever is listed under Window > Preferences > Groovy > Compilers, but, AFAIK, you can't change to an arbitrary version of the compiler by simply changing the groovy-all jar in the guts of the plugin dir.
You can install new compiler versions using the update site or eclipse marketplace
Update: install additional compiler versions through Help > Install new Software, select Groovy update site and expand the Extra Groovy Compilers session:
Note i'm using snapshot update site, because i like to live dangerously.
