Failed to copy artifact or file with maven packaging a web application

I have a problem packaging a web application based on vaadin. I have two projects in my workspace called project A and project B. Project A is referencing B and the dependencies are resolven within the workspace and degub mode correctly, by adding the project to the classpath.

Now if I try to maven package, I always get the error

Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.2:war (default-war) on project A: Failed to copy file for artifact [com.dscsag.dscxps:ProjectB:jar:0.0.1-SNAPSHOT:compile]: C:\some_path\target\classes (Access is denied) -> [Help 1]

What should I do?

It seem to relate with security because the log said "(Access is denied)". Maybe output jar of project B exist and there are some processes still ready from it, so that you cannot overwrite output file. Or maven don't have privilege to write output file to class folder.
