Build fails after upgrade(Mendix Studio Pro v.9.6.7 to v.9.12.0))

After updating from Mendix Studio Pro v.9.6.7 to v.9.12.0 and running Locally, I got the following error message. It was working fine with Mendix Studio Pro v.9.6.7.   [rtlauncher:container$] INFO Evictions for component 'project-userlib': Evicted C:\workspace\deployment\model\lib\userlib\commons-lang3-3.7.jar by C:\workspace\deployment\model\lib\userlib\commons-lang3-3.11.jar. Evicted C:\workspace\deployment\model\lib\userlib\commons-lang3-3.9.jar by C:\workspace\deployment\model\lib\userlib\commons-lang3-3.11.jar. Evicted C:\workspace\deployment\model\lib\userlib\okhttp-3.13.1.jar by C:\workspace\deployment\model\lib\userlib\okhttp-4.10.0.jar. 2022-09-14 16:13:03.187 INFO - M2EE: Added admin request handler '/prometheus' with servlet class 'com.mendix.metrics.prometheus.PrometheusServlet' [rtlauncher:container$] INFO Container start took 4163. Ready to accept admin requests.   I deleted the ".mendix-cache" folder referring to the following question, but it could not be resolved.   It worked fine on other team members' environments, so it doesn't seem to be a jar file issue. Please let me know if anyone knows the solution.

The answer is their in your question itself.

In userlib folder there are duplicate jar files with two version for example common-lang 3.7 and 3.11

Keep the latest one and delete the older one.


Make sure you don't have any duplicate jar file in userlib.
