I can import a simple example project that has the ‘eclipse’ plugin applied just fine. Are you using the latest version of Buildship? If so, can you share a reproducible example? ---

Yes, I use the latest version of Buildship. Unfortunately, I’m not allowed to share my project. Does the stacktrace not help? ---

I’m afraid a stacktrace is not enough to analyse your problem: it only tells that your build script tries to create the `eclipse` task multiple times. ---

Note - we are actively using the eclipse plugin in Gradle presently and are evaluating switching to Buildship (hoping we can use it). We have been forced to use the eclipse plugin quite extensively, with classpath configuration modifications, classpath file/XML modifications (to reference maven projects in the same workspace), etc… ---

Actually no, we did what we wanted. We created an ‘eclipse’ task at the root project (that does NOT have eclipse plugin applied to it, it is not a Java project, just a parent to many) to avoid accidental invocation of the ‘eclipse’ task on all subprojects that have that task. ---

It doesn’t matter whether it’s a Java project, Buildship adds the eclipse plugin to all projects. The custom task is preventing that. You could for instance add a ´doFirst {}´ block that throws an exception to the eclipse task of the subprojects. This makes it even clearer they shouldn’t be used while not preventing Buildship from working.
