Maven Compilation Error: How to Fix \'No Compiler Provided\'?

Maven Compilation Error: No Compiler Provided

When compiling a project in Eclipse using m2eclipse, it's crucial to ensure that you're using a Java Development Kit (JDK) rather than a Java Runtime Environment (JRE). If the error message "No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?" appears, follow these steps to rectify the issue:

1. Verify Installed JREs:

   • Open your Eclipse IDE and navigate to Window > Preferences > Java > Installed JREs.
   • Check if there is an entry with a JDK listed.

2. Select Execution Environment:

   • If a JDK is installed, select it as the Execution Env. Click OK to save the changes.

3. Update Maven Project:

   • Right-click on the affected project and select Maven > Update Project.

Additional Solution:

If the above steps don't resolve the issue, try changing the Maven JRE.

1. Go to Run > Run Configurations and select the Maven Build you're running.
2. Click the JRE tab and select the "Workspace default JRE" option.
