multi-pom in intellijIDEA. Error adding module to project: null

I wanted to make a multi-pom project in Intellij (2020.3.4). In one Maven project, I right-click ->New -> Module -> Maven. select parent to "my project". However, even if parent is not specified, I get the error: Error adding module to project: null. (at the same time, it adds a regular folder with the module name and an empty pom.xml inside) (This happens with any archetype). I didn't find any solutions on the Internet at all. Only downgrade to the old version of Intellij IDEA and that solution was published 10 years ago. Tell me what is the problem? Or what to do? Does not work only with "Maven". With "Java" and "Spring Inizializr" it works.

I reinstalled windows. (I needed it anyway) and installed intellij IDEA 2021.3 instead of 2020.3. Everything worked. Some of this has affected. Perhaps reinstalling the same version would also solve this problem.

In Intellij goto File -> Project Structure -> Project SDK -> [Select Your Installed SDK Version] -> Ok
And try to add the new module, it worked for me.

Caused by: java.lang.NoClassDefFoundError: org/apache/log4j/Logger in XPages

In our XPages project now we have to use Quartz Scheduler. I've tried to import all necessary jars which includes the following:
c3p0-0.9.5.2
log4j-1.2.16.jar
quartz-2.3.0-SNAPSHOT.jar
quartz-jobs-2.3.0-SNAPSHOT.jar
slf4j-api-1.7.7.jar
slf4j-log4j12-1.7.7.jar
I've imported all the jars to our project but when loading a page (which doesn't even call quartz or anything) I get the following exception:

I suspect that this problem is related to Axis 1.4 log4j-1.2.8.jar incompatible with XPages?
I've tried to follow the advice and added the following to java.policy (section grant codeBase):
permission java.lang.RuntimePermission "setContextClassLoader";
permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
But still with no luck.
What's the problem?
Thanks in advance

I've resolved the issue by adding all logging libraries:
log4j-1.2.16.jar
slf4j-api-1.7.7.jar
slf4j-log4j12-1.7.7.jar
to lib/ext

I cannot find the log it's referring to.
I have installed JRE, JDE, Tizen SDK and in Device Manager, I've hit "Permit to install applications".
The TV is a UE55KS7005
Any idea what is wrong?

UPDATE:
Installing Tizen applications for 2015, 2016 and 2017 was successful using the Java Version 8 Update 181 with Tizen CLI Version 2.4.50. But the problem described above following the prerequisites here (https://developer.tizen.org/ko/development/tizen-studio/download/installing-tizen-studio/prerequisites) still persists when installing the application on 2018.
java.lang.ClassNotFoundException:
org.tizen.ncli.subcommands.tv.SecureCmdVer2_0_device

Couldn't that be related with the fact that older TVs can't receive packages from newest Tizen SDKs. See answers on this question. Try to install an older version of Tizen Studio or SDK from here http://download.tizen.org/sdk/Installer/

Unsupported Class Version during Maven build in Jenkins

I've seen a few of these questions on here, but none of the solutions/tips seem to be pointing me in the right direction. So I have 3 JDK's installed in the locations of "/opt/java/6", "/opt/java/7", and "/opt/java/8". All of these are set in the global Jenkins configuration. Jenkins itself is run using Java 8 which is the system default JRE that I set manually through alternatives (I'm using CentOS 7). I had a bunch of old projects that are built using maven and the maven compiler plugin which is set to source=1.6 target=1.6 . Every time I try to execute a build with the Java 6 JDK I get

This indicates that there's Java 7 interfering somewhere, but I'm not sure where.
The code is 1.6 compliant and most of the projects have no dependencies, so I'm not sure why this is happening. If I execute maven outside of Jenkins, the projects build just fine with JDK 6, so its leading me to think there's a misconfiguration in Jenkins somewhere, but I'm not sure where since everything seems to be as it should be. The paths to the JDKs are set properly in the global config and the projects themselves are set to use the specified JDK's. I apologize if its a duplicate question or something silly, but I've been trying to figure this out for days with no results. Everyone just says to check the paths and make sure there are no dependent artifacts built with a later JDK and I'm sure that this is not the problem.

You have an old java version. For example in my case I´m compiling an old product so I have to keep the java deprecated version.
So the solution was to download a newest jdk and configure the JAVA_HOME in the slave.
http://lmarccdk12.ptx.fr.sopra:14000/computer//configure in the section Advanced/JavaPath=/root/jdk1.7.0_79/bin/java (that´s the version I chose)
You will see the following message in the slave launch log:
[SSH] Starting slave process: cd "/root" && /root/jdk1.7.0_79/bin/java -jar slave.jar

Your Jenkins job is of type "Maven project", and this job type has a limitation in that it cannot run a Maven build with a JDK version that is older than the Java version under which Jenkins is run.
Beginning with Jenkins 2.357 (released on June 28, 2022) and the forthcoming 2.361.1 LTS release, Jenkins requires Java 11 or newer. Therefore, you can no longer run Maven projects with JDKs 1.6, 1.7 and 1.8. The minimum version is now Java 11.
To resolve this, you may:
Create a Freestyle project and use Invoke top-level Maven targets to invoke Maven, or create a Jenkins Pipeline project. In both cases, using an older JDK will be possible.
Use JDK 11 but set source and target version to the older Java version. I haven't tried that though, and I believe this option may cause other trouble.
For further information, see also Jenkins requires Java 11 or newer and Maven Builds Fails After Upgrade
