报错:Maven Resources Compiler: Maven project configuration required for module 'xxx' isn't available.

新建maven项目时，Problems中报错：Error:Maven Resources Compiler: Maven project configuration required for module 'xxx' isn't available. Compilation of Maven projects is supported only if external build is started from an IDE.【Maven资源编译器:模块“xxx”所需的Maven项目配置不可用。只有从IDE启动外部构建时，才支持Maven项目的编译。】

解决办法：在idea中，点击 Build 然后选择选择Build Project(建置专案)【或 Rebuild Project(重新建置项目)】即可
