Could not delete /.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/appname/WEB-INF/lib. May be locked by another process

Question

I am trying to run an web app. In the beginning it was going well, but I had to delete some jars from the project folder. I didn't delete the jars using eclipse. So, I started to get these errors:

Publishing failed with multiple errors
Could not delete C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/fj21-tarefas/WEB-INF/lib. May be locked by another process.
Could not delete C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/fj21-tarefas/WEB-INF. May be locked by another process.

I tried to delete my whole project and code it again. But it doesn't work. I also deleted the Tomcat server but again it doesn't work. Then I realized that to "fix" this problem I have to delete this folder:

C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/fj21-tarefas/WEB-INF.

And clean the server and the project. But when I close eclipse and open again I get the same error, then I have to do this process.

Anyone here knows how to fix this kind of tomcat bug?

Answer 1

there is already a post which answer this question you need to:

1. Clean Server
2. Clean Tomcat Work Directory

link to the page: Why is my publishing failing in Tomcat v7.0 Server because of locks by another process?

Answer 2

Simply delete the server and then add it again,then restart your eclipse.It worked for me.

Answer 3

Close the eclipse and go to below location(depends on your system locaiton)

C:/Users/maniceto/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/

and delete tmp0 directory now start eclipse and it will work fine.

Answer 4

i don know the exact reason for this problem but i was clear the same issue by restarting my system. so restart your system once, it may gives solution for your problem.
