Plugin execution not covered by lifecycle configuration in Pom.xml OpenHAB

Question

I am trying to build OpenHAB open source project using eclipse. But getting below error in pom.xml

I am not aware of Maven build system, for now just trying to compile and build OpenHAB.

Plugin execution not covered by lifecycle configuration: org.apache.karaf.tooling:karaf-maven-plugin: 4.0.3:features-generate-descriptor (execution: default-features-generate-descriptor, phase: compile)

Here is he pom.xml file:

Answer 1

This is just a problem inside your eclipse. The message "Plugin execution not covered by lifecycle configuration" simply means, that eclipse doesn't know about the "org.apache.karaf.tooling:karaf-maven-plugin" plugin that is used inside your pom.

Solution: Do a right-click on the parent project in eclipse an select "Run As" ==> "Run as maven build...", enter "clean package" into the "goal" field an hit "Run" to build the project (Build-Artifact will then appear in the "target" directory).

Answer 2

Default solution to define via pluginManagement something like this:

<pluginManagement>
  <plugins>
    <plugin>
     <groupId>org.eclipse.m2e</groupId>
     <artifactId>lifecycle-mapping</artifactId>
     <version>1.0.0</version>
     <configuration>
       <lifecycleMappingMetadata>
         <pluginExecutions>
           <pluginExecution>
             <pluginExecutionFilter>
               <groupId>some-group-id</groupId>
               <artifactId>some-artifact-id</artifactId>
               <versionRange>[1.0.0,)</versionRange>
               <goals>
                 <goal>some-goal</goal>
               </goals>
             </pluginExecutionFilter>
             <action>
               <ignore/>
             </action>
           </pluginExecution>
         </pluginExecutions>
       </lifecycleMappingMetadata>
     </configuration>
    </plugin>
  </plugins>
</pluginManagement>
