How to Fix Maven Compiler Error: \'No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?\'

Maven Compiler Error: "No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?"

This error occurs when Eclipse cannot find a Java Development Kit (JDK) to compile your project. This is because you are likely using a Java Runtime Environment (JRE) instead, which does not include the necessary utilities for compiling code.

Solution:

1. Configure Eclipse to use a JDK:

   • Navigate to Window > Preferences > Java > Installed JREs.
   • Ensure that a JDK (e.g., JDK 1.7.xx) is listed.
   • Select the JDK and click OK.

2. Update Maven Project:

   • Right-click your project and select Maven > Update Project.

Additional Tips:

• Check the Maven JRE settings in your project's run configurations:

  • Click Run > Run Configurations.
  • Select the Maven Build you are running.
  • Navigate to the JRE tab and select Workspace default JRE.
• Ensure that the JDK you configured in Eclipse is the same version as the Maven Java version in your pom.xml file.
• If the issue persists, try cleaning your project (Project > Clean).
• Check your firewall settings to ensure that traffic is not being blocked between Eclipse and the JDK.
