Maven compiler plugin null pointer

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project ProjectName: Fatal error compiling: CompilerException: NullPointerException -> [Help 1]

原因：代码编译出错被掩盖了

The underlying problem is usually caused by a compiler error that gets masked. To find out the compiler error,
pass -Dmaven.compiler.forceJavacCompilerUse=true to the mvn command line.
After fixing the compiler error, the problem goes away.

在pom里增加<forceJavacCompilerUse>true</forceJavacCompilerUse> 找出错误原因，修改后再编译
