java only project check

[chameleon82]

I have multi-module gradle project for java libraries and would like to use plugin for compatibility-check. However, all my modules use plugins { java-library } and checker tasks unavailable until I will add kotlin("jvm") plugin.

Is there any way to configure plugin with no kotlin sources?

@chameleon82 at the moment, BCV could be only configured for projects where one of Kotlin plugins was applied (jvm, multiplatform, or kotlin-android).

As a quick and dirty workaround, you may check how Kotlin stdlib use BCV:
