Sample Eclipse project

We're using the jspc-maven-plugin plugin to pre-compile our JSP files before bundling these up in to a WAR file. By default, M2E gives the error "M2E plugin execution not covered", and as per the instructions at http://wiki.eclipse.org/M2E_plugin_execution_not_covered I'm documenting my findings here.

Because the jsp compilation is not required for WTP to work within Eclipse, simply disabling the plugin is sufficient for everything to work nicely; 

    <pluginManagement>
    	<!--  Disable the jspc plugin when running in Eclipse -->
        <plugins>
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>org.codehaus.mojo.jspc</groupId>
                                    <artifactId>jspc-maven-plugin</artifactId>
                                    <versionRange>[1.0.0,)</versionRange>
                                    <goals>
                                        <goal>compile</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <ignore/>
                                </action>
                            </pluginExecution>
                        </pluginExecutions>
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>

I've also attached a trivial project that demonstrates this behaviour - with the above configuration jspc-maven-plugin is ignored when running in Eclipse, but is correctly used to pre-compile the JSP files when the project is packaged using Maven.
