eclipse，代码中有异常，项目中却不显示红叉

 1.单个项目修改

项目上右键-->properties-->java compiler-->building-->enable project specific setting-->build path problems-->选中abort   Incomplete build path/Circular dependencies  这两个选项修改为Warning

2.整个环境修改
window->preferences->java->compiler->building->build path problems-->选中abort   Incomplete build path/Circular dependencies  这两个选项修改为Warning
