解決eclipse： Resource is out of sync with the file system 報錯問題

轉載：http://blog.csdn.net/lotusyangjun/article/details/5611352

這是檔案系統不同步的問題，是因為在eclipse之外對工程中的resource進行修改引起的；但是，有時沒有在eclipse之外進行修改，也會報類似的錯誤。 
解決辦法：需要手動重新整理一下資源管理員。 
（1）在eclipse中，工程目錄右鍵，選擇F5（refresh） 
（2）設定eclipse自動重新整理。 
           通過Window->Preferences->General->Workspace，選中Refresh automatically

 

eclipse中的項目無法查看源檔案，報錯：resource is out of sync with the file system。唯一的問題，在eclipse工程之外的地方修改了源檔案但是沒有重新整理。MyEclipse內建協助文檔：
Don't forget to refresh!
Whenever you use external tools to modify workspace files, you must perform a Refresh from within Eclipse to make the workspace aware of the changes.If you get a resource out of sync error in Eclipse it is a sign that there are resources in Eclipse that have
been modified outside of Eclipse. 
One solution is to perform a refresh (available from a resource's popup menu) on any resources or projects that where modified outside of Eclipse.
There is also a preference to refresh automatically. 但是設定為自動重新整理在工程比較大時代價有點大！ Window->Preferences->General->Workspace，選中Refresh automatically。
