SpotBugs support is broken in Gradle 6.4

[jjathman]

After upgrading to Gradle 6.4 we get this error:

Caused by: java.lang.NoSuchMethodError: org.gradle.process.internal.worker.WorkerProcessFactory.singleRequestWorker(Ljava/lang/Class;Ljava/lang/Class;)Lorg/gradle/process/internal/worker/SingleRequestWorkerProcessBuilder;

From what I can tell this API is no longer used in recent versions of the SpotBugs Plugin. But the quality plugin pulls in an old version.

Reading the docs it looks as though I should be able to use a newer version of the plugin by setting

classpath "gradle.plugin.com.github.spotbugs.snom:spotbugs-gradle-plugin:4.0.8"

but that doesn't seem to work and I still see the error. I'm wondering if it's because the group changed for the plugin?

Spotbugs plugin 4 was a rewrite and it works differently. I tried to update some time ago, but it wasn't simple so I postpone it.

Not only group changed between 2 and 4:

gradle.plugin.com.github.spotbugs.snom:spotbugs-gradle-plugin:4.0.8
com.github.spotbugs:spotbugs-gradle-plugin:2.0.1

but also package, so the current quality plugin is not compatible with the new spotbugs plugin.

I mention this problem in docs:
you can only disable automatic spotbugs support (quality.spotbugs = false) and apply new spotbugs plugin manually.

I will, of course, support the new spotbugs plugin but it may require some time.

Yep, disabling SpotBugs is what we've done for now. I'm just recommending our teams to not upgrade to Gradle 6.4 for now, I don't think there were any must-have features for us anyones. Thanks for taking a look at it!

I'm facing the same issue. My jenkins build is getting the latest Gradle whenever it builds the project. Since Gradle 6.4 released recently my build is getting failed due SpotBugs issue in ru.vyarus.quality plugin. Appreciate if we could have a fix for this soon.

4.3.0 released
