The error 'Source option 5 is no longer supported. Use 6 or later' on Maven compile occurs when the project's source level is set to 5, which is an outdated version. This issue affects developers who use Maven for their Java projects and have not updated their build configuration.
This error can be frustrating because it prevents the compilation process from completing successfully. However, with a simple update to the Maven compiler plugin, this issue can be resolved.
💡 Why You Are Getting This Error
The primary cause of this error is that the project's source level has not been updated to a supported version. The Maven compiler plugin requires at least source level 6 to function correctly.
Another possible reason for this error could be due to an incorrect configuration in the pom.xml file, specifically the compiler plugin's source and target options.
🛠️ Step-by-Step Verified Fixes
Updating the Source Level
Step 1: Open the pom.xml file and locate the compiler plugin section.
Step 2: Update the source level from 5 to 6 by changing the following line: 5 to 6.
Step 3: Save the changes to the pom.xml file and try compiling the project again using $ mvn compile.
Checking Compiler Plugin Configuration
Step 1: Verify that the compiler plugin's target level is set correctly. The target level should be at least 1.6.
Step 2: Check if there are any other configuration issues in the pom.xml file that could be causing the error.
Step 3: If necessary, update the pom.xml file with the correct configuration and try compiling the project again.
✨ Wrapping Up
