Maven compile mixed Java + Groovy 1.7 project, using gmaven-plugin
compilation, gmaven-plugin, groovy, java, maven
Solution
I had the same problem. I was missing the providerSelection configuration setting for 1.7.
Try this configuration and it should work for you.
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>gmaven-plugin</artifactId>
<version>1.2</version>
<configuration>
<providerSelection>1.7</providerSelection>
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.gmaven.runtime</groupId>

Problem
As per the top two answers in: maven dependencies groovy. I'm trying to compile a mixed Java 6 + Groovy project with Maven, using the GMaven-plugin from org.codehaus.gmaven. Up until yesterday we were using the old `1.6.0` version of Groovy (never changed it after we finally got it working), but since `1.7.0` is now stable I thought we'd switch to that. If only things were that simple.. The problems I'm now encountering seem to be two fold: - `Groovy 1.6` is somehow still picked up as the default. (as show in the stacktrace below) - groovy:generateStubs stops with a build error: Unexpected node: Node[7:1,64,ANNOTATIONS] Does anyone know how to solve the above two problems, or can provide a working pom to compile `Java 6` code intermixed with `Groovy 1.7` code with Maven? There's a lot of confusing / contradicting / outdated documentation on compiling old versions of Groovy using gmaven / groovy.maven / groovy.maven.gmaven that's really not helping things right now.. For reference, here's part of my pom.xml & the Maven -e output: ``` <dependencies> <dependency> <groupId>org.codehaus.groovy</groupId> <artifactId>groovy-all</artifactId> <version>1.7.0</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.codehaus.gmaven</groupId> <artifactId>gmaven-plugin</artifactId> <version>1.2</version> <dependencies> <dependency> <groupId>org.codehaus.gmaven.runtime</groupId> <artifactId>gmaven-runtime-1.7</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>org.codehaus.groovy</groupId> <artifactId>groovy-all</artifactId> <version>1.7.0</version> </dependency> </dependencies> <executions> <execution> <goals> <goal>generateStubs</goal> <goal>compile</goal> <goal>generateTestStubs</goal> <goal>testCompile</goal> </goals> </execution> </executions> </plugin> </plugins> </build> ``` Stacktrace: ``` [INFO] ------------------------------------------------------------------------ [INFO] Building Client [INFO] task-segment: [clean, package] [INFO] ------------------------------------------------------------------------ [INFO] [clean:clean {execution: default-clean}] [INFO] [groovy:generateStubs {execution: default}] [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Unexpected node: Node[7:1,64,ANNOTATIONS] [INFO] ------------------------------------------------------------------------ [INFO] Trace org.apache.maven.lifecycle.LifecycleExecutionException: Unexpected node: Node[7:1,64,ANNOTATIONS] at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:719) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalWithLifecycle(DefaultLifecycleExecutor.java:556) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal(DefaultLifecycleExecutor.java:535) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures(DefaultLifecycleExecutor.java:387) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments(DefaultLifecycleExecutor.java:348) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifecycleExecutor.java:180) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:328) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:138) at org.apache.maven.cli.MavenCli.main(MavenCli.java:362) at org.apache.maven.cli.compat.CompatibleMain.main(CompatibleMain.java:60) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) 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) Caused by: org.apache.maven.plugin.MojoExecutionException: Unexpected node: Node[7:1,64,ANNOTATIONS] at org.codehaus.gmaven.plugin.MojoSupport.execute(MojoSupport.java:85) at org.codehaus.gmaven.plugin.stubgen.AbstractGenerateStubsMojo.execute(AbstractGenerateStubsMojo.java:60) at org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:490) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:694) ... 17 more Caused by: org.codehaus.gmaven.runtime.support.stubgen.UnexpectedNodeException: Unexpected node: Node[7:1,64,ANNOTATIONS] at org.codehaus.gmaven.runtime.support.stubgen.parser.NodeSupport.ensure(NodeSupport.java:96) at org.codehaus.gmaven.runtime.support.stubgen.model.ModelFactorySupport.identifier(ModelFactorySupport.java:896) at org.codehaus.gmaven.runtime.support.stubgen.model.ModelFactorySupport.importDef(ModelFactorySupport.java:185) at org.codehaus.gmaven.runtime.support.stubgen.model.ModelFactorySupport.process(ModelFactorySupport.java:122) at org.codehaus.gmaven.runtime.support.stubgen.model.ModelFactorySupport.create(ModelFactorySupport.java:90) at org.codehaus.gmaven.runtime.support.stubgen.model.ModelFactorySupport.create(ModelFactorySupport.java:61) at org.codehaus.gmaven.runtime.v1_6.StubCompilerFeature$StubCompilerImpl.render(StubCompilerFeature.java:101) at org.codehaus.gmaven.runtime.v1_6.StubCompilerFeature$StubCompilerImpl.compile(StubCompilerFeature.java:90) at org.codehaus.gmaven.plugin.stubgen.AbstractGenerateStubsMojo.compile(AbstractGenerateStubsMojo.java:160) at org.codehaus.gmaven.plugin.stubgen.AbstractGenerateStubsMojo.process(AbstractGenerateStubsMojo.java:131) at org.codehaus.gmaven.plugin.ComponentMojoSupport.doExecute(ComponentMojoSupport.java:60) at org.codehaus.gmaven.plugin.MojoSupport.execute(MojoSupport.java:69) ... 20 more ```
