Eclipse發布項目時部署失敗情況解決辦法

 If a file is locked, you can wait until the lock times out

 

MyEclipse中的java項目，翻來複去的折騰修改，最後終於部署失敗了，部署時提示的錯誤資訊如下：

Deployment failure on Tomcat  6.x. Could not copy all resources to E:\apache-tomcat-6.0.16\webapps\HebbnWebServices. If a file is locked, you can wait until the lock times out to redeploy, or stop the server and redeploy, or manually remove the deployment at
E:\apache-tomcat-6.0.16\webapps\HebbnWebServices

再次點部署按鈕時就會提示如下：

Undeployment Failure could not be redeployed because it could not be completely removed in the undeployment phase. the most common cuase of this problem is attempting to redeploy while the server is running,which has locked one or more files.

to correct the deployment you will need to stop the server and then redeploy the project before restarting the server.

解決的辦法就是在Eclipse中把項目中引用的jar檔案重新加一遍就行了，基本原因就是以前的jar檔案不存在了，但是項目資訊中還有，即項目的.classpath檔案中還有不存在的jar檔案引用。

可以右鍵點項目名稱，選擇Properties,選擇Java Build Path,選擇Libraries,把所有項目中的jar都remove，然後再點"add jars"，把項目中的jar檔案都加進來，再次部署就正常了。
