In the Installed Software tab, check whether the module you just selected is in this list.

Check whether eclipse already supports the creation of Maven projects:
File --> New --> Other , find the Maven item, if everything is normal, it means that m2eclipse is correct installed.

Reminder 1:
      Eclipse will report the following error
      Eclipse is running in a JRE , but a JDK is required Some Maven plugings may not work when importing projects or updating source folders
     to solve:
      This is because Eclipse runs on JRE by default, and some functions of m2eclipse require the use of JDK. The solution is to configure the eclipse.ini file and add the vm configuration to point to the JDK Java
