| [tycho-user] Problem with tycho-compiler-plugin with implementing a supertype method |
Hi, I have made my plug-in projects in Eclipse and converted to Maven/Tycho projects. In Eclipse everything compiles: Source of Class: public class RemoteServiceAdminImpl implements RemoteServiceAdmin { @Override public Collection<ExportRegistration> exportService(ServiceReference reference, Map<String, Object> properties) { *** } } It compiles in Eclipse with JDK 1.6 and JDK 1.7. The Interface RemoteServiceAdmin is imported from a local repository which contains the bundle osgi.enterprise_4.2.0.v201108120515.jar When I try with maven clean install from my parent project with configuration <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> Or with configuration source and target 1.7, it cannot compile. I get this error message from tycho-compiler: [ERROR] Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:0.15.0:compile (default-compile) on project ***: Compilation failure: Compilation failure: [ERROR] ***/RemoteServiceAdminImpl.java:[39,0] [ERROR] public class RemoteServiceAdminImpl implements RemoteServiceAdmin { [ERROR] ^^^^^^^^^^^^^^^^^^^^^^ [ERROR] The type RemoteServiceAdminImpl must implement the inherited abstract method RemoteServiceAdmin.exportService(ServiceReference, Map<String,?>) [ERROR] ***/RemoteServiceAdminImpl.java:[60,0] [ERROR] public Collection<ExportRegistration> exportService(ServiceReference reference, Map<String, Object> properties) { [ERROR] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ [ERROR] Name clash: The method exportService(ServiceReference, Map<String,Object>) of type RemoteServiceAdminImpl has the same erasure as exportService(ServiceReference, Map<String,?>) of type RemoteServiceAdmin but does not override it [ERROR] ***/RemoteServiceAdminImpl.java:[60,0] [ERROR] public Collection<ExportRegistration> exportService(ServiceReference reference, Map<String, Object> properties) { [ERROR] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ [ERROR] The method exportService(ServiceReference, Map<String,Object>) of type RemoteServiceAdminImpl must override or implement a supertype method [ERROR] 3 problems (3 errors) [ERROR] -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:0.15.0:compile (default-compile) on project ***: Compilation failure at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:213) 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:84) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:59) at org.apache.maven.lifecycle.internal.LifecycleStarter.singleThreadedBuild(LifecycleStarter.java:183) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:161) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:320) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:156) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:537) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:196) at org.apache.maven.cli.MavenCli.main(MavenCli.java:141) 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:601) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:290) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:230) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:409) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:352) Caused by: copied.org.apache.maven.plugin.CompilationFailureException: Compilation failure at copied.org.apache.maven.plugin.AbstractCompilerMojo.execute(AbstractCompilerMojo.java:418) at org.eclipse.tycho.compiler.AbstractOsgiCompilerMojo.execute(AbstractOsgiCompilerMojo.java:179) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209) ... 19 more If I change in Eclipse the implementation of the method (public Collection<ExportRegistration> exportService(ServiceReference reference, Map<String, Object> properties) to public Collection<ExportRegistration> exportService(ServiceReference reference, Map<String, ?> properties), Eclipse gives me an error: The method must override or implement a supertype class method. What is the problem with this or what configuration can solve this? Thanks, Regards, Mattias |
