CheckStyle doesnt work with Mypy extension or on lower versions

[pitris90]

Checkstyle messages me this: {"message":"LineLength is not allowed as a child in Checker"}.... It worked with this xml on my main computer and i think even on this one...

the important part of XML file looks like this:

And when I switch Checkstyle version on 10 (where it was originally), it writes this: {"message":"com/puppycrawl/tools/checkstyle/api/AuditListener","cause":{"message":"com.puppycrawl.tools.checkstyle.api.AuditListener"}}

And this in Java Support extension:

EDIT: I found a problem... I remembered that I recently installed also Mypy extension for handling Mypy for Python. And as you can see there is some weird conflict. I solved it by turning off Mypy extension for my Java workspace

[jdneo]

sounds wired, I'm trying to understand why a Python extension could affect Java ones. 🤔

And one more thing: checkstyle rules differs from different checkstyle version. You need to make sure the version and your rules are compatibale

[pitris90]

There is an option called: Mypy: Run Using Active Interpreter Use the active Python interpreter (selected in the Python extension) to run dmypy itself, instead of the mypy.dmypyExecutable setting. Note: your code is always checked against the active interpreter – this setting only controls the interpreter used to run dmypy itself.

I had it set to True, because on False it didnt work on my Python files and this option when it is set to True seems to be a problem

I simply have to use latest version - 10 - otherwise plugin has some problems too

But you are using Checkstyle to check your Java code right? I cannot understand my the Python's setting would affect that.

Of course :D But that Python extension was enabled too and with that setting it caused this weird conflict. I don't understand it either... You can take a look on it, its Mypy extension ->

And try to turn that mentioned setting to on

[pitris90]

But there is still this message when i set checkstyle version on 8.43 for example (In IntelliJ it works with this version too): {"message":"com/puppycrawl/tools/checkstyle/api/AuditListener","cause":{"message":"com.puppycrawl.tools.checkstyle.api.AuditListener"}}

[jdneo]

Would you mind to share a sample project?

Would you mind to share a sample project?

For fixing that message i mentioned above? Because this speccifically is my school project which, I am afraid, I can't share 😄
