Maven Compilation Error: No Compiler Provided

When attempting to compile a project in Eclipse using m2eclipse, you may encounter the error: "No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?" This error indicates that you have not properly configured your Eclipse IDE with a Java Development Kit (JDK).

To resolve this issue, follow these steps:

1. Verify Installed JREs:

   In Eclipse, navigate to Window > Preferences > Java > Installed JREs. Ensure that you have a JDK listed as one of the installed JREs.

2. Configure Execution Environment:

   Select the JDK you want to use as your execution environment. To do this, click the dropdown next to Execution Env and choose your desired JDK.

3. Update Maven Project:

   After selecting your JDK, right-click on your project and select Maven > Update Project. This will refresh the Maven configuration and ensure that it uses the correct JDK.

Additional Troubleshooting:

If you still encounter the error, consider checking the following:

• Maven JRE Configuration:

  Go to Run > Run Configurations and select the Maven Build you are running. Click on the JRE tab and ensure that the option "Workspace default JRE" is selected. This will ensure that the Maven Build uses the same JDK as your Eclipse IDE.

By following these steps, you can configure Eclipse properly and resolve the "No compiler is provided" error when compiling projects using m2eclipse.
