Problems encountered during text search.
File 'yao111/bin/jarlist.cache' has been skipped, problem while reading: ('Resource is out of sync with the file system: '/yao111/bin/jarlist.cache'.').
Resource is out of sync with the file system: '/yao111/bin/jarlist.cache'.
解决方法：原因是文件系统不同步问题resource is out of sync with the file system。是因为在eclipse之外对工程中的resource进行修改引起的，手动刷新一下项目就不会出现错误了。
