Ktlint checks generated source since 12.1.0

[ede-wolf-gls]

Since version 12.1.0 of your ktlint gradle plugin, my android build fails.

> Task :app:generateSomeCode FAILED

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':app:generateSomeCode' (type 'GenerateSomeCodeTask').
  - Gradle detected a problem with the following location: '.../app/build/generated/source/constants'.

    Reason: Task ':app:runKtlintCheckOverMainSourceSet' uses this output of task ':app:generateSomeCode' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.

    Possible solutions:
      1. Declare task ':app:generateSomeCode' as an input of ':app:runKtlintCheckOverMainSourceSet'.
      2. Declare an explicit dependency on ':app:generateSomeCode' from ':app:runKtlintCheckOverMainSourceSet' using Task#dependsOn.
      3. Declare an explicit dependency on ':app:generateSomeCode' from ':app:runKtlintCheckOverMainSourceSet' using Task#mustRunAfter.

    For more information, please refer to https://docs.gradle.org/8.5/userguide/validation_problems.html#implicit_dependency in the Gradle documentation.

I tried to exclude the generated sources from ktlint checks, but this didn't work

ktlint {
    filter {
        exclude("**/generated/**")
    }
}

I include the generated sources in the main source set like this:

android {
//...
    sourceSets {
        get("main").kotlin.srcDir("<generated source directory>")
    }
}

Could someone help? Maybe I configure something wrong.

Until this is fixed put this in .editorconfig:

# Disable ktlint on generated source code, see
# https://github.com/JLLeitschuh/ktlint-gradle/issues/746
[**/build/generated/source/**]
ktlint = disabled

[**/build/generated/source/**]
ktlint = disabled

This did not help unfortunately ☹️

Worked in https://github.com/pachli/pachli-android/pull/376 - look at the CI runs for that PR, you'll see the first one failed because of this issue, and adding this editorconfig fixed it.

Hhm,

for me

[**/build/generated/**]
ktlint = disabled

did not work, but

[build/generated/*/main/**]
ktlint = disabled

did!

Same problem here.
