import to eclipse not working with Gradle 3.1 #8

Closed rasenderhase closed 7 years ago

rasenderhase commented 7 years ago

as of Gradle 3.1 the project import is not working any more:

org.gradle.tooling.model.UnsupportedMethodException: Unsupported method: HierarchicalEclipseProject.getIdentifier(). The version of Gradle you connect to does not support that method. To resolve the problem you can change/upgrade the target version of Gradle you connect to. Alternatively, you can ignore this exception and read other information from the model. at org.gradle.tooling.model.internal.Exceptions.unsupportedMethod(Exceptions.java:34) at org.gradle.tooling.internal.adapter.ProtocolToModelAdapter$InvocationHandlerImpl.invoke(ProtocolToModelAdapter.java:342) at com.sun.proxy.$Proxy40.getIdentifier(Unknown Source) at com.gradleware.tooling.toolingclient.internal.deduplication.EclipseProjectDeduplicator$RenamedEclipseProjectTracker.<init>(EclipseProjectDeduplicator.java:87) at com.gradleware.tooling.toolingclient.internal.deduplication.EclipseProjectDeduplicator.deduplicate(EclipseProjectDeduplicator.java:38) at com.gradleware.tooling.toolingclient.internal.deduplication.DeduplicatingGradleConnection$DeduplicatingEclipseModelBuilder$DeduplicatedModelResults.iterator(DeduplicatingGradleConnection.java:126) at com.gradleware.tooling.toolingmodel.repository.internal.ModelResultsConverter$ConvertedModelResults.iterator(ModelResultsConverter.java:67) at org.eclipse.buildship.core.workspace.internal.SynchronizeCompositeBuildJob.fetchEclipseProjects(SynchronizeCompositeBuildJob.java:77) at org.eclipse.buildship.core.workspace.internal.SynchronizeCompositeBuildJob.runToolingApiJob(SynchronizeCompositeBuildJob.java:65) at org.eclipse.buildship.core.util.progress.ToolingApiJob$1.run(ToolingApiJob.java:73) at org.eclipse.buildship.core.util.progress.ToolingApiInvoker.invoke(ToolingApiInvoker.java:63) at org.eclipse.buildship.core.util.progress.ToolingApiJob.run(ToolingApiJob.java:70) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

I think it's because they have removed the method HierarchicalEclipseProject.getIdentifier() in Gradle 3.1. Where/Why is the plugin calling this method?

Could you try running your build from the command line and see if the same problem exhibits itself? When I do so, using a gradle 3.1 wrapper, I'm not able to recreate. It looks like you are running this in Eclipse, and I'm wondering if that might be the problem. Thanks

Hi, you are right. It's working in the console. And now even in Eclipse. ❓ ❓ ❓

I tend to blame [https://en.wikipedia.org/wiki/Gremlin]. If you continue to have problems, you might open a ticket with the Eclipse project, or the maintainer of the gradle plugin for Eclipse.
