eclipse，代碼中有錯誤，項目或者java類中卻不顯示紅叉

修改eclipse代碼提示級別
1.單個項目修改
項目上右鍵-->properties-->java compiler-->building-->enable project specific setting-->build path problems-->選中abort   Incomplete build path/Circular dependencies  這兩個選項修改為Error

2.整個環境修改

window->preferences->java->compiler->building->build path problems-->選中abort   Incomplete build path/Circular dependencies  這兩個選項修改為Error
