Hi Team , I ran "mvn clean install" in my linux machine to build a maven Project, But getting below error:

[ERROR] com/porterhead/sms/DefaultSmsServiceTest has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
[ERROR] org.apache.maven.surefire.booter.SurefireBooterForkException: There was an error in the forked process

Hello @Niroj ,

You need to double check the PATH environment setting.Please make sure you have the bin subdirectory for the latest JDK version at the top of the PATH list.

java.exe executable is in C:\Program Files\Java\jdk-13\bin directory, so that is what you need to have in PATH.

Use this tool to quickly verify or edit the environment variables on Windows. It allows to reorder PATH entries. It will also highlight invalid paths in red.

If you want your code to run on lower JDK versions as well, change the target bytecode version in the IDE. What happens is that you build the code with Java 13 and 13 language level bytecode (target) and try to run it with Java 8 which is the first (default) Java version according to the PATH variable configuration.

The solution is to have Java 13 bin directory in PATH above or instead of Java 8. On Windows you may have C:\Program Files (x86)\Common Files\Oracle\Java\javapath added to PATH automatically which points to Java 8 now:

If it's the case, remove the highlighted part from PATH and then logout/login or reboot for the changes to have effect. You need to Restart as administrator first to be able to edit the System variables (see the button on the top right of the system variables column).

Hope it is helpfull!!
Thank you!!
