The project cannot be built until build path errors are resolved

我简单的在project里选择clean一下就解决了,不知算不算lucky。

ps.后果很严重,这样每个project 都要clean下才行。。
之后我又在project->Properties->Android下勾选了Is Library.
看到其他人的解决方案,归纳有以下几步:

1,看看project -- Build Automatically有没有勾上?如果没有,勾上以后,clean一下,重启eclipse

2,看看你的lib里面有没有不用的jar包,看你的.classpath文件中有没有错误的路径.

3,这是最重要的一点,有problems视图中查看有没有关于本项目的错误信息,一般都会有这样的话:      The project cannot be built until build path errors are resolved 然后下面提示unbound classpath, 一般在.classpath中删除这些path就可以了

4. 安装Tomcat后,确保{tomcat_home}/common/lib文件夹下有jasper-runtime.jar、jsp-api.jar、servlet-api.jar、jndi.jar几个文件。启动Eclipse,第一次启动会有一个配置过程,选择菜单上的window/preferences,选java/classpath variables,New添加一个名为JDK_TOOLS并指向你的{jdk_home}/lib/tools.jar的环境变量。


如此以来,Eclipse运行正常了。
