You need to upgrade the parent pom to version 5.4  
Also align the bom in the dependencyManagement section accordingly to use `bom-2.479.x`  
Then you can remove the explicit jakarta.servlet dependency there as well

You have to specify a version for the bom. The latest version is `3875.v1df09947cde6`  
Also make sure you’re using java17

</div>

the pom.xml looks good I think.  
Other things to check

- You must be using maven 3.9.6 or higher
- you must use java 17

</div>

run maven with `-X` to get debug output. Use `-U` to force update dependencies

Ensure that `JAVA_HOME` env variable also points to java 17

I have followed all your suggestions, but I am still getting the same error, even in the debug output

I took your pom.xml from [here](https://community.jenkins.io/t/error-during-plugin-upgrade-from-2-440-3-to-2-479-1/25524/7)  
This works fine on my machine.  
So something else is wrong on your machine it’s not the pom

I get the error with the unknown packaging when java 11 is used.  
So ensure that JAVA\_HOME points to Java 17 and not Java 11

Hey Markus,  
My project runs fine, but sometimes this error occurs. I checked on different systems, and this error appears frequently. Sometimes the project runs fine, but other times the error occurs. Why is the project not consistent? I’m using Eclipse ID version Version: 2024-09 (4.33.0) & Build id: 20240905-0614
