title: Maven project in Eclipse - Perhaps you are running on JRE rather than JDK
body: <p>I have the same problem as in the post: <a href="https://stackoverflow.com/questions/19655184/no-compiler-is-provided-in-this-environment-perhaps-you-are-running-on-a-jre-ra">No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?</a></p>
  
  <p>I follow the steps of the first comment in that post. But I can not find a JDK folder. To illustrate this I add a picture how it looks like:</p>

  <p>So, as you can see, I have no jdk- folder . And I would like to know, why? And what to do? When I run "clean install" from the command line, then everything is okay. In Eclipse, I get the message that I run perhaps on JRE instead of JDK.</p>
  
  <p>edit: I have also installed the jdk folder. Here again, a picture:
