Project configurator "EnableJdtAptM" required by plugin execution "maven-compiler-plugin:3.1:compile" is not available
<p>I have no idea how to fix this. I imported a Maven project that actually hasn't anything to do with Spring but I am getting </p>

<blockquote>
  <p>Project configurator "<code>org.springframework.ide.eclipse.boot.properties.editor.maven.EnableJdtAptM2EProjectConfigurator</code>" required by plugin execution "<code>org.apache.maven.plugins:maven-compiler-plugin:3.1:compile</code> (execution: default-compile, phase: compile)" is not available. To enable full functionality, install the project configurator and run Maven->Update Project Configuration.</p>
</blockquote>

<p>Of course I already run a Maven update but it does not resolve this error. </p>

<p>So what is this even about?</p>
