也可以解决  针对Maven项目不显示Maven Dependencies库的解决方案

保持标准的输出目录，可以参考正常的项目，将.classpath进行复制，如下是一个

第二份相对简单点，如果项目目录不对，可以选择抄一份正常的项目或者部分摘抄。按照相应复制，刷新项目。

maven项目分为src目录，resource目录，test/src目录，test/resource目录： 其中src和resource对应到项目的target\classes目录，如果在src目录调用classpath，则class的根目录为target\classes； test/src，test/resource对应到test-classes目录，如果在test/src目录调用cla...
