maven… Failed to clean project: Failed to delete ..\org.ow2.util.asm-asm-tree-3.1.jar

I use STS(spring tool suite) + maven plugin.

Every time when I run my application using maven-clean I see following error:

Answer 1

For linux users: possible solution.

Build error due to "Failed to delete < any-file-or-folder >" will occur if there is by chance of only delete access provided to root user rather to normal-user.

Fix : type ll command to list file that cannot be deleted, if the file is given root access, change to normal user by :

sudo chown -R user-name:user-name filename

Later try for maven clean and build.

Answer 2

I solved mine by doing:

• mvn clean
• mvn install
• mvn clean install

For some reasons it worked for me . Good luck !!

Answer 3

Please close all the browser tab. And next time when you try to upload war from another place except target folder.

Answer 4

If you run into this error in an IDE like Eclipse or IntelliJ, you may have one or more debug windows open and paused on a break-point. Terminate them.

Answer 5

Try disabling Project->Build Automatically.

As Scorpio suggested, there's a process running that's got a lock on a file somewhere.

I have a large multi-module maven project that regularly fails on clean and this resolves it for me. I re-enable Build Automatically when I'm done.

Answer 6

I had similar issue. Earlier I was using Maven 3 to build the project. After switching to maven 2 , I had the above error.

Solved it by switching to Maven 3.
