In the POM configuration maven Plugin hint error "Plugin execution not covered by lifecycle configuration" solution

An error in Eclipse's tip in its pom file is as follows:

Plugin execution not covered by lifecycle Configuration:org.apache.maven.plugins:maven-compiler-plugin:3.1: Compile (Execution:default-compile, phase:compile)

This means that M2E does not define the plug-in when it executes the MAVEN lifecycle management, so there is a hint of an error, in fact M2E provides an extension mechanism, and we can eliminate this error message by doing the following:

1. Enter the Window->preferences->maven configuration and enter the lifecycle mapping settings, such as:

As you can see, the file name for the M2E management maven lifecycle is lifecycle-mapping-metadata.xml, and the path to which it is stored

2. Next we will go to the corresponding path to modify the Lifecycle-mapping-metadata.xml file, but will find that the file in the location of the hint does not exist, then this time

Locate the file (for example) in the Org.eclipse.m2e.lifecyclemapping.defaults_xxxxxx.jar file under plugins in the installation directory of Eclipse:

By extracting the software, you can discover that the Lifecycle-mapping-metadata.xml file is indeed in the jar package, extracting it from the jar package and placing it in the path shown in the previous illustration.

3. Open the Lifecycle-mapping-metadata.xml file and add the unrecognized plugin to the file:

4. After the modification is complete, the "Update Maven projects on startup" option on the M2E configuration will be ticked and the eclipse can be removed to eliminate the error.
