说一下问题：项目右键->Run as->Maven install，结果控制台就报这个错误
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:testCompile (default-testCompile) on project myPro: Fatal error compiling: tools.jar not found: C:\Program Files\Java\jre7\..\lib\tools.jar -> [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.
解决办法：
终归原因，是maven需要jdk，而不是jre。具体解决办法看我的这篇文章
