after that the project status is "Building" and after I restart the project manually the changes I made didn't apply on the server.
Here's the pom file (I didn't change anything):

I use jBoss Developer Studo under windows 7, and JDK 1.7 64 bit

Answer 1

I just created a new Tomcat 7 application and the build finished without any error. There are couple of solutions:
Create a new application and push the changes again. Just in case there was some issue with that gear.
Create an empty file called force_clean_build inside your existing application .openshift/markers directory. Commit the file and push the changes. This will remove the .m2 repository and download all the dependencies and plugins again.
