Why doesn't Maven's mvn clean ever work the first time?

Question

Nine times out of ten when I run mvn clean on my projects I experience a build error. I have to execute mvn clean multiple times until the build error goes away. Does anyone else experience this? Is there any way to fix this within Maven? If not, how do you get around it? I wrote a bat file that deletes the target folders and that works well, but it's not practical when you are working on multiple projects. I am using Maven 2.2.1.

Answer 1

It may be that your IDE or some other process is holding on to the the "target" folder and preventing maven from deleting it.
