報錯信息：
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'.
解決方法：原因是文件系統不同步問題resource is out of sync with the file system。是因爲在eclipse之外對工程中的resource進行修改引起的，手動刷新一下項目就不會出現錯誤了。
