Description

I am trying to contribute to the project and as a task-list to do before doing it, it appears that a build should be run with the maven wrapper:

./mvnw clean package 
./bin/generate-samples.sh
./bin/utils/export_docs_generators.sh

The first step hangs after a test to generate a java-helidon-server; this is not happening with -DskipTests option.
Could this be somehow fixed so contributors can build and run the tests on the command line? Thank you!

openapi-generator version

Test build on master branch (currently at 6d48d7342112f3a4d1c543054575a21424ec8f45)

Suggest a fix

I am not sure why this is happening, so I can't help here.

Reproduce the hang with ./mvnw clean package or ./mvnw clean test under WSL or Git Bash, focusing on the test that generates java-helidon-server. Compare the behavior with -DskipTests and inspect the relevant build or test entry points found during reproduction. Done means the Maven wrapper completes the test and package commands without hanging.
