Hello,
I encountered an error while upgrading my plugin from version 2.440.3 to 2.479.1. Here are the details:

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

The version of the bom is not correct. 3193.v330d8248d39e doesn’t exists for bom-2.479.x

get this same error after removing the version

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

Now I’m getting this error:

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
9

I have maven version 3.9.9 & java 17, then how i fixed the error ?

10

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

11

Ensure that JAVA_HOME env variable also points to java 17

12

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
This works fine on my machine.
So something else is wrong on your machine it’s not the pom

14

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

15

Hey Markus Winter, it’s working fine now. Thank you so much for your support!

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
