Building Jar in IDEA freezes

Question

I am trying to build a jar in IntelliJ Idea. (Project structure-Artifacts-Add artifact-Choose module-Create jar). Then I am pressing Build-Build artifacts-Choose my Jar-Build. And then Idea just reading pom.xml in background and no jar for me. What could be the solution to this?

Answer 1

I do it like in this instruction. But before I did File | Invalidate Caches and it helps.
