Maven 報錯：Compilation of Maven projects is supported only if external build is started from an IDE.

1. Maven 報錯： Error:Maven Resources Compiler: Maven project configuration required for module 'yourProjectName' isn't available. Compilation of Maven projects is supported only if external build is started from an IDE. 緣由：修改了項目對應的 文件夾名和 module 名。 解決： 若是是 idea 的話，右擊 pom.xml 文件，選擇最下面的 「 Add as maven build file」，而後編譯器會從新構建，就行了
