Question

i am using maven 2 and eclipse helios, and after installing the plugin M2E 1.0 from here:

http://download.eclipse.org/technology/m2e/releases

i am getting the following error in eclipse:

Project configurator "org.jboss.tools.maven.apt.MavenCompilerAptProjectConfigurator" is not available. 
To enable full functionality, install the project configurator and run Maven->Update Project Configuration

also i am getting the following two errors:

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile 
(execution: default-compile, phase: compile)

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile 
(execution: default-testCompile, phase: test-compile)

the build section in my pom file:

<build>

  <resources>

            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>

  </resources>

Answer 1

i fixed it by adding the ignore tag to the mentioned plugins as follows:

  <plugin>

    <groupId>org.eclipse.m2e</groupId>
    <artifactId>lifecycle-mapping</artifactId>
    <version>1.0.0</version>
    <configuration>
        <lifecycleMappingMetadata>
            <pluginExecutions>
                <!-- copy-dependency plugin --> 
                <pluginExecution>
                    <pluginExecutionFilter>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-dependency-plugin</artifactId>
                        <versionRange>[1.0.0,)</versionRange>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                    </pluginExecutionFilter>
                    <action>
                        <ignore />
                    </action>
                </pluginExecution>
                <pluginExecution>
                    <pluginExecutionFilter>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>
                            maven-compiler-plugin
                        </artifactId>
                        <versionRange>[2.3.2,)</versionRange>

                            <goal>testCompile</goal>
                            <goal>compile</goal>
                        </goals>
                    </pluginExecutionFilter>
                    <action>
                        <ignore></ignore>
                    </action>
                </pluginExecution>

            </pluginExecutions>
        </lifecycleMappingMetadata>
    </configuration>
