Why, when building mavens, npm opens Karmu and then does nothing?

Question

Angular

I generated a project using the Angular CLI. Added there pom.xml.
It uses a special maven plugin .
pom code:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      </plugin>
    </plugins>

  </build>

</project>

So, I do mvn clean install. At the beginning, everything goes as it should, the cache is cleared, npm install is performed, tests are run. Log:

And a browser tab opens with Karma. And that’s it, nothing happens next, I don’t see the long-awaited BUILD SUCCESS.

How to fix it?

Answer 1

Forgot --single-run?
And don't call mvn installif you don't want to install the built artifacts in ~./m2/repository. Enough mvn verify.
PS By the way, why do you run tests in the generate-resources phase, and not in the test phase?
