Getting "NoSuchMethodError: 'org.apache.maven.project.MavenProject org.eclipse.m2e.core.project.configurator.ProjectConfigurationRequest.getMavenProject()'"

[davidmichaelkarr]

I very recently installed Eclipse 2022-09, with m2e 2.0.5.20220912-1211 and 4.7.0.v202209192046-e2209 of the "Groovy-Eclipse M2E integration".

Whenever I try to update a Maven project, I get an error dialog about "An internal error occurred during: "Updating Maven Project".". The error log has this:

!ENTRY org.eclipse.core.jobs 4 2 2022-09-20 13:51:08.188 !MESSAGE An internal error occurred during: "Updating Maven Project". !STACK 0 java.lang.NoSuchMethodError: 'org.apache.maven.project.MavenProject org.eclipse.m2e.core.project.configurator.ProjectConfigurationRequest.getMavenProject()' at org.codehaus.groovy.m2eclipse.GroovyProjectConfigurator.addJavaProjectOptions(GroovyProjectConfigurator.java:108) at org.eclipse.m2e.jdt.internal.AbstractJavaProjectConfigurator.configure(AbstractJavaProjectConfigurator.java:167) at org.codehaus.groovy.m2eclipse.GroovyProjectConfigurator.configure(GroovyProjectConfigurator.java:49) at org.eclipse.m2e.core.project.configurator.AbstractLifecycleMapping.configure(AbstractLifecycleMapping.java:125) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.lambda$6(ProjectConfigurationManager.java:475) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.executeBare(MavenExecutionContext.java:350) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.execute(MavenExecutionContext.java:262) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.updateProjectConfiguration(ProjectConfigurationManager.java:469) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.lambda$4(ProjectConfigurationManager.java:413) at java.base/java.util.Collection.removeIf(Collection.java:576) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.updateProjectConfiguration0(ProjectConfigurationManager.java:407) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.lambda$3(ProjectConfigurationManager.java:339) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.executeBare(MavenExecutionContext.java:350) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.execute(MavenExecutionContext.java:262) at org.eclipse.m2e.core.internal.embedder.MavenExecutionContext.execute(MavenExecutionContext.java:205) at org.eclipse.m2e.core.internal.embedder.MavenImpl.execute(MavenImpl.java:1093) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.updateProjectConfiguration(ProjectConfigurationManager.java:338) at org.eclipse.m2e.core.ui.internal.UpdateMavenProjectJob.runInWorkspace(UpdateMavenProjectJob.java:80) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:43) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

Looks like m2e went wild with Java 17 in 2.0:

I backed up to 2022-06 and it's fine now. I'll watch for news here.

If you want to go with 2022-09, you can get the old m2e release from this update site: https://download.eclipse.org/technology/m2e/releases/1.20.1

I can try to work around some of the API changes. GroovyProjectConfigurator depends on the JDT M2E framework. So I'd need for that to be updated or rewrite to be standalone.
