I am trying to build a Jenkins plugin. What I already did was creating a Maven project from the hello-world-plugin archetype. But when I do **mvn verify** , it gives me the following error: ![image](https://europe1.discourse-cdn.com/flex013/uploads/jenkins/original/2X/8/8dd57c18aefddef665f7465eb75b0244c63bc4e3.png) How can I point it to the hpi package? ---

Hello @joris and welcome to this community. 👋 Please, next time you want to show us logs, do a textual copy and paste, not a screenshot. 🙏 I had that kind of error when trying to build a very old plugin with a recent version of Maven. Could you please show us your `pom.xml`? ---

In that case, the developer was trying to use Java 8 to create a new Jenkins plugin. The Jenkins project stopped supporting Java 8 for development of new plugins over a year ago. ---

yes, is me. sorry for enfore your double time. Repeat my results in this: archetype 1.22 + Java 17 work well. archetype 1.7 + Java 8 work well. No continue attempts.
