Why are Java inspections running in Kotlin files?

[skasi-surya]

We have an inspections XML profile that is passed into Qodana. This includes inspections for multiple languages - Kotlin, Java, Android, Groovy etc.

One specific inspection, Java -> Declaration redundancy -> Unused declaration is showing false positives after upgrading from Qodana 2021.2 to 2022.2.

Qodana github action in workflow:

- name: Qodana Scan
    uses: JetBrains/[email protected]
    with:
      pr-mode: false
      use-annotations: true
      upload-result: false
      args: --linter,jetbrains/qodana-jvm-community:2022.2,--fail-threshold,0

Firstly, why are Java inspections running on Kt files? Also, as seen in the screenshot, it is clearly a false positive as the parameters are being used.

qodana.yml and Inspections.xml have been included in the zip for reference.

Hello,

Could you please try using the jetbrains/qodana-jvm-community:2022.3 linter? I couldn't reproduce the issue in version 2022.3. In 2022.2 there are indeed these false positive "Unused Declaration" problems.

Have tried with jetbrains/qodana-jvm-community:2022.3 , same issue persists.

Oh, I could reproduce the issue using IntelliJ IDEA. The problem seems to be in our Kotlin Plugin. I reported it to the responsible team (KTIJ-23958). Feel free to vote for the issue on our tracker to get notifications when there are any updates.
