Unable to Compile: "No Compiler Provided"?
When attempting to compile a project in Eclipse using m2eclipse, an error message stating "No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?" may appear. To resolve this issue, follow these steps:
- Verify JDK Installation: Ensure that the JDK path is properly set in Eclipse. Navigate to "Windows" -> "Preferences" -> "Installed JREs" and check for a JDK entry.
- Set Execution Environment: Select the installed JDK and set it as the "Execution Environment." Click "OK" to confirm the changes.
- Maven Update: Right-click the project and select "Maven" -> "Update Project."
Additionally, it may be necessary to change the Maven JRE by accessing "Run" -> "Run Configurations." Select the Maven Build you are running and navigate to the "JRE" tab. Choose the option "Workspace default JRE." A screenshot below illustrates this step.
