But my environment was not able to resolve that variable. I am wondering from where was this variable supposed to be configured. I could manually modify it to become 1.8. But that is not what the code was meant to do, isn’t it?

Maybe you could modify “javaVersion”to 1.8 in root pom.xml to solve your problem. If you have found any mistake, please feel free to correct it.

A co-worker reported that in his development environment, the kylin release 2.5.3 would build as is. So it must be the environment difference that can cause the problem.
