本人是安卓实习生一枚，遇到这个问题，求大神解答。

Error:Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at http://gradle.org/docs/2.4/userguide/gradle_daemon.html

Please read the following process output to find out more:
