When reloading the project from pom in idea8.0 I get the following exception: .apache.maven.plugin.PluginExecutionException: Mojo execution failed. at org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:601) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures(DefaultLifecycleExecutor.java:498) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegmentForProject(DefaultLifecycleExecutor.java:265) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments(DefaultLifecycleExecutor.java:191) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifecycleExecutor.java:149) at org.apache.maven.DefaultMaven.execute_aroundBody0(DefaultMaven.java:223) at org.apache.maven.DefaultMaven.execute_aroundBody1$advice(DefaultMaven.java:304) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:1) at org.apache.maven.embedder.MavenEmbedder.execute_aroundBody2(MavenEmbedder.java:904) at org.apache.maven.embedder.MavenEmbedder.execute_aroundBody3$advice(MavenEmbedder.java:304) at org.apache.maven.embedder.MavenEmbedder.execute(MavenEmbedder.java:1) at org.jetbrains.idea.maven.embedder.MavenEmbedderWrapper$2.execute(MavenEmbedderWrapper.java:87) at org.jetbrains.idea.maven.embedder.MavenEmbedderWrapper$5.execute(MavenEmbedderWrapper.java:207) at org.jetbrains.idea.maven.embedder.MavenEmbedderWrapper$5.execute(MavenEmbedderWrapper.java:204) at org.jetbrains.idea.maven.embedder.MavenEmbedderWrapper$6.run(MavenEmbedderWrapper.java:220) at com.intellij.openapi.application.impl.ApplicationImpl$5.run(ApplicationImpl.java:2) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) at com.intellij.openapi.application.impl.ApplicationImpl$1$1.run(ApplicationImpl.java:10) Caused by: org.apache.maven.plugin.MojoExecutionException: No providers found matching selection: default at org.codehaus.groovy.maven.plugin.MojoSupport.execute(MojoSupport.java:85) at org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:579) ... 22 more Caused by: org.codehaus.groovy.maven.feature.ProviderException: No providers found matching selection: default at org.codehaus.groovy.maven.runtime.loader.DefaultProviderManager.select(DefaultProviderManager.java:111) at org.codehaus.groovy.maven.plugin.ProviderMojoSupport.provider(ProviderMojoSupport.java:108) at org.codehaus.groovy.maven.plugin.ComponentMojoSupport.doExecute(ComponentMojoSupport.java:58) at org.codehaus.groovy.maven.plugin.MojoSupport.execute(MojoSupport.java:69) ... 23 more If I turn on the logging I get the enclosed stack trace (attachment). It seems like plexus is probably not initialized properly (or in some unexpected state). This is using maven 2.0.9. I have seen other reports that this is also happening in eclipse. I have tried debugging this to find more details but It is really hard because there is some "compatibility" aop involved. There may also be a version number issue, since maven 2.0.9 does not seem to be using the exactly same version of plexus (1.0-alpha-9-stable-1 for maven 2.0.9). I hope you actually understand enough plexus to make heads/tails of this problem, since it seems to be way above my head. The enclosed project (report2.tar) can be opened in idea8.0 (and probably eclipse). If you make a symbolic change to the pom.xml and choose a re-import, the problem is reproducable 100%.
