IntelliJ IDEA :org.jdom.input.JDOMParseException:
在应用osc git 或 其它项目托管平台结合intelliJ Idea 时，启动项目/Junit单元测试，会出现如下错误：

原因：
在从项目托管平台（如:osc git）中pull出项目代码时，若遇到版本冲突，会写入 .idea文件夹下msic.xml或module.xml文件中版本冲突信息,
形式类似SVN中检出代码冲突标记格式；
只要将其按所需内容，将冲突标记删除即可；形如（==================v10001>）；
若还未能解决，可将msic.xml与module.xml两文件拷贝到其它目录，删除.idea 文件夹及下属所有文件，重新make项目后，idea会自动重新生成.idea
文件，再将此两文件（msic.xml与module.xml）拷贝到原来目录下，即可。
记录一下。
