报错内容：

Eclipse Problems中出现这样的Error：

DescriptionResourcePathLocationType

The project was not built due to "Could not delete '/quartz-monitor/bin/com'.". Fix the problem, then try refreshing this project and building it since it may be inconsistentquartz-monitorUnknownJava Problem

产生原因：

在项目的Java Build Path中设置了多个Source folder并且这几个folder冲突了，具有相同的包名或者大小写之后一致的包路径。

解决方案：

1、设置编译输出路径。

2、将冲突的包名更改一下。
