Utku Gultopu updated MNG-6033: ------------------------------ Description: I am following the maven plugin [tutorial|https://maven.apache.org/guides/plugin/guide-java-plugin-development.html]. I have created the the {{GreetingMojo}} class and the POM as described in the tutorial, and run {{mvn install}} but I am getting the same error as indicated in [this|http://stackoverflow.com/questions/18999401/basic-maven-plugin-project-not-working-mojo-plugin-descriptors-not-generating] question (also by the issue MNG-5346). [3.2.2 release notes|http://maven.apache.org/docs/3.2.2/release-notes.html] state that the issue is fixed. I have the 3.3.9 version of Maven. However, I still get: {{org.apache.maven.plugin.descriptor.InvalidPluginDescriptorException: No mojo definitions were found for plugin: sample.plugin:hello-maven-plugin}} The full stack trace is: {code} [ERROR] Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor (default-descriptor) on project hello-maven-plugin: Error extracting plugin descriptor: 'No mojo definitions were found for plugin: sample.plugin:hello-maven-plugin.' -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor (default-descriptor) on project hello-maven-plugin: Error extracting plugin descriptor: 'No mojo definitions were found for plugin: sample.plugin:hello-maven-plugin.' at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:212) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:116) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:80) at org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder.build(SingleThreadedBuilder.java:51) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:128) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:307) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:193) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:106) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:863) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:288) at org.apache.maven.cli.MavenCli.main(MavenCli.java:199) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:289) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:229) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:415) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:356) Caused by: org.apache.maven.plugin.MojoExecutionException: Error extracting plugin descriptor: 'No mojo definitions were found for plugin: sample.plugin:hello-maven-plugin.' at org.apache.maven.plugin.plugin.AbstractGeneratorMojo.execute(AbstractGeneratorMojo.java:245) at org.apache.maven.plugin.plugin.DescriptorGeneratorMojo.execute(DescriptorGeneratorMojo.java:92) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:134) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:207) ... 20 more Caused by: org.apache.maven.plugin.descriptor.InvalidPluginDescriptorException: No mojo definitions were found for plugin: sample.plugin:hello-maven-plugin. at org.apache.maven.tools.plugin.scanner.DefaultMojoScanner.populatePluginDescriptor(DefaultMojoScanner.java:126) at org.apache.maven.plugin.plugin.AbstractGeneratorMojo.execute(AbstractGeneratorMojo.java:233) ... 23 more {code} Am I missing something here? was: I am following the maven plugin [tutorial|https://maven.apache.org/guides/plugin/guide-java-plugin-development.html].
