Re-run Maven using the -X switch to enable full debug logging.

This is what I have tried to fix the problem:

  • Uninstalled NetBeans 7.2, removed .m2 directory, removed .nbi directory (I don't know if this belongs to NetBeans), rebooted and reinstalled NetBeans 7.2
  • Uninstalled NetBeans 7.2 and installed NetBeans 7.0.1
  • modified the POM file of the project
  • modify the context.xml file in META-INF/ folder of my project to point it to a different path.
  • Correctly install Maven by adding the proper environment variables (works for mvn --version in cmdline but still error in NetBeans)

My projects used to build and run perfectly with no problems when I was using NetBeans 7.0.1, until I installed NetBeans 7.2. That's when I started getting this error. I do have a POM file in my project. The error doesn't go away no matter what I try.

Other strange behavior:

  • When I try to create a new Maven Webapplication in NetBeans, it always creates it under the root of my drive E:\ in a folder even though I explicitly tell it to install it under my projects folder.

What works:

  • The only time when my projects successfully build and run is when I run them in my Windows XP SP3 virtual machine. So I don't know what to think here. What application or configuration is at fault? I find it very difficult to troubleshoot.

  • Running this command: https://cwiki.apache.org/confluence/display/MAVEN/MissingProjectException thus using an explicit path to my project. I don't want to do this every time. I want it to work like it's supposed to.

Specs:

  • JDK 1.7
  • Sourcecode java
  • version: 1.6
  • OS: Windows 7 x64
  • Server used: Tomcat 7.x
Solution

  • I had the same problem when I set command promp default directory in the windows register to E:\ according: http://www.sevenforums.com/customization/77997-change-command-prompt-default-directory.html

    After I deleted this regkey netbeans worked right for me.
