jhipster Using docker image all tests failing - jhipster

Question

For my project, I need to have a certain jhipster version.
But I also want to play around with all the new jhipster features (version 5+).
Therefore, my idea is to run the newest jhipster inside a docker container, so nothing intereferes with my project setup.
I followed the offical jhipster install guide.
The installation was succesful.
Now comes there part where I am stuck.
Using ./gradlew test, all tests fail.
I tried the ./gradlwe test in both directories, meaning once in the docker container directory (docker container exec -it jhipster bash --> then inside the app folder doing yarn install and then ./gradlew test)
and from my local directory where the volume got mounted (~/jhipster).
What am I missing?
For anyone interested in seeing the tests failing (this is how all of them look like):
Task :test
org.jhipster.health.web.rest.LogsResourceIntTest > changeLogs FAILED

Answer 1

I solved this issue, even though I do not understand HOW this is a fix.
Since I have a working .yo-rc.json I used docker cp to copy this file into the docker container and then ran jhipster.
Now I removed that file and ran a blank jhipster with the same configuration parameters and after this all gradlew test did pass.
