Where is my Jar file, no Jar is created after compile?

Created November 27, 2024 10:23

I'm having a hard time migrating from Netbeans to IntelIJ, I have some projects in Spring Boot & maven that I can successfully run and I can successfully compile in IntelIJ but no JAR is created. Where is the JAR? I searched all the files of the project no JAR is created.

Another problem is that I can't run Maven from the IntelIJ terminal, mvn command is not found. I tried to change “Maven home path” from “Bundled (Maven 3)” to “Use Maven wrapper” but still mvn is not found.

This is the output of the compile:

Hi, does that help by check Delegate IDE build/run actions to Maven in the menu File | Settings |Build, Execution, Deployment \> Build Tools \> Maven \> Runner options?

There also should be a jar task in the Maven tool window. You can run it then a jar file will be created under the project's target folder.
