如果myeclipse 报如下错误
A cycle was detected in the build path of project
如果我们的项目包含多个工程（project），而它们之间又是循环引用的关系，那么Eclipse在编译时会抛出如下一个错误信息：
“A
cycle was detected in the build path of project:
XXX”
解决方法非常简单：
Eclipse Menu ->
Window -> Preferences... -> Java -> Compiler -> Building ->
Building path problems -> Circular dependencies ->
将Error改成Warning
