A cycle was detected in the build path of project ‘x’ . The cycle consists of projects {x,y} Build Path Problem
环境：eclipse，jdk 1.8.2 maven
从svn 检出Maven 项目
好多项目莫名有感叹号，然后看gg 一下，好多说build path 有问题，检查了build path 发现没有有感叹号的地方，也没有 missing的jar包
不得要领。
然后看eclipse markers 窗口 有好多错误。
其中多的就是
A cycle was detected in the build path of project ‘x’ . The cycle consists of projects {x,y} Build Path Problem
网上查了一下 ，
里面有提供解决方案。
Preferences > Java > Compiler > Building > Build path problems > Circular dependencies 将值由error 改为warning 即可
