Dear All! I'm investigating this manual about Developing Ant Plugins for Maven 2.x: http://maven.apache.org/guides/plugin/guide-ant-plugin-development.html
I try to create the easiest HelloWorld plugin. As described in this manual: 1) I create Ant script 2) I create mojo 3) I create pom 4) I build it and install (successfully) And than I try to run it: c:\> mvn org.myproject.plugins:hello-plugin:hello Here is what I got: [INFO] Scanning for projects... [INFO] ------------------------------------------------------------------------ [ERROR] FATAL ERROR [INFO] ------------------------------------------------------------------------ [INFO] null [INFO] ------------------------------------------------------------------------ [INFO] Trace java.lang.NullPointerException at org.apache.maven.plugin.descriptor.PluginDescriptor.getMojo(PluginDescriptor.java:262) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.getMojoDescriptor(DefaultLifecycleExecutor.java:1529) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.segmentTaskListByAggregationNeeds(DefaultLifecycleExecutor.java:386) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifecycleExecutor.java:138) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:334) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:125) at org.apache.maven.cli.MavenCli.main(MavenCli.java:272) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java:315) at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) at org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:430) at org.codehaus.classworlds.Launcher.main(Launcher.java:375) [INFO] ------------------------------------------------------------------------ [INFO] Total time: < 1 second [INFO] Finished at: Tue Jul 10 20:02:10 EEST 2007 [INFO] Final Memory: 1M/2M [INFO] ------------------------------------------------------------------------ It seems to me that it is a bug in maven or in developer's guide.
