I have Spring-Roo geerated project, that fails to start in jetty via mvn jetty:run
Caused by: java.lang.UnsupportedClassVersionError: com/roo124/domain/Company : Unsupported major.minor version 51.0
What does Unsupported major.minor version mean? And where can I see that 51.0 value?
it means that the classes, you are trying to run, were compiled with a newer version of java than the one you are currently using.
Please check the output of mvn --version and make sure you are using a current JVM.
