[Bug]: It seems to be impossible to run the plc4py build with skip tests

[chrisdutz]

What happened?

When building PLC4X it sometimes is usefull to build all parts locally, skipping all tests. IntelliJ has a checkbox in the maven panel, which I think passes the "-DskipTests" to the maven build. If this is set, the plc4py build fails.

In our build README we tell people to build with skipTests to skip the tests, if the build fails we might have problems with the next release.

It seems that when "skipTests" is enabled, there are two modules missing:

• black
• deptry

If I comment out the two executions requiring them (python-black, python-dependency-check), then I am able to build the project with "skipTests". It seems that when not set, these dependencies are pulled in in the python-test-compile step ... at least can I see them being mentioned in the log then.

Just thought this might help in tracking down the issue.
