Following errors happen in groovybooking example when imported to JBDS (ignoring missing Maven artifacts): Description Resource Path Location Type Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:build-helper-maven-plugin:1.5-redhat-1:add-test-source (execution: add-test-source, phase: generate-test-sources) pom.xml /groovybooking-tests line 84 Maven Project Build Lifecycle Mapping Problem Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:build-helper-maven-plugin:1.5-redhat-1:add-source (execution: add-source, phase: generate-sources) pom.xml /groovybooking-web line 200 Maven Project Build Lifecycle Mapping Problem Plugin execution not covered by lifecycle configuration: org.codehaus.gmaven:gmaven-plugin:1.4:testCompile (execution: default, phase: test-compile) pom.xml /groovybooking-web line 133 Maven Project Build Lifecycle Mapping Problem Plugin execution not covered by lifecycle configuration: org.codehaus.gmaven:gmaven-plugin:1.4:generateTestStubs (execution: default, phase: generate-test-sources) pom.xml /groovybooking-web line 133 Maven Project Build Lifecycle Mapping Problem Plugin execution not covered by lifecycle configuration: org.codehaus.gmaven:gmaven-plugin:1.4:generateStubs (execution: default, phase: generate-sources) pom.xml /groovybooking-web line 133 Maven Project Build Lifecycle Mapping Problem Plugin execution not covered by lifecycle configuration: org.codehaus.gmaven:gmaven-plugin:1.4:compile (execution: default, phase: compile) pom.xml /groovybooking-web line 133 Maven Project Build Lifecycle Mapping Problem
These errors are related to M2e plugin in Eclipse/JBDS and they are not really important. It says only that M2e plugin doesn't know how to handle some maven plugins used in example's pom.xml file. More information at http://wiki.eclipse.org/M2E_plugin_execution_not_covered As summary - you have got two options: 1. download/install plugin for haddling the affected maven plugin lifecycle see section "m2e maven plugin coverage status" on referenced above wiki page URL 2. Ignore it by adding of plugin configuration for org.eclipse.m2e:lifecycle-mapping:1.0.0 I don't like any from these 2 solutions and even it shows error it is build-able. I am not considering this as a bug, just a technical note could be added for this particular case.
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: BZ-830202 and BZ-830214 The Groovybooking example in Seam 2.3 requires an additonal Maven plugin for integration with JBoss Developer Studio, which is not installed by default. This leads to plugin errors, which can be worked around by following the import wizard instructions to install build-helper-maven-plugin and gmaven-plugin. The example will run regardless of these errors, however.
