最近做个大创项目导入别人的项目出现Multiple annotations found at this line:
- java.io.IOException cannot be resolved to a type
- String cannot be resolved to a type
- java.io.IOException cannot be resolved to a type
- No exception of type ServletException can be thrown; an exception type must be a
subclass of Throwable
- The method getContextPath() from the type HttpServletRequest refers to the missing
type String
甚至String cannot be resolved to a type这样的各种错误,但项目在原机器上是正常运行的。
解决办法两个:
一:jdk不匹配。对方的jdk版本跟你的不同,甚至是1.6和1.7之间的差别,则必然出现这样的错误。改成你自己的jdk就好。对项目右键properties->java build path之后就能找到了。
二:若不是这个问题,那试试project-clean。
三:以上都不能解决的时候就要考虑导入的项目缺少某些.jar或者代码有错误。
