Maven编译项目报错：Fatal error compiling: CompilerException: NullPointerException

一、问题描述

 

maven编译项目报如下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project collector: Fatal error compiling: CompilerException: NullPointerException -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

[ERROR] For more information about the errors and possible solutions, please read the following articles:

二、解决方法

 

这种错基本上就是JDK版本的问题，我用的maven插件版本是：

	org.apache.maven.plugins
	maven-compiler-plugin
	3.8.1
	
		1.8
		1.8
		UTF-8
	

指定的JDK是1.8，而我环境变量中配置的是JDK14。。所以一编译就报这种错。。。就环境变量中的JDK版本改为JDK1.8就行了。
