Running AppEngine App in Development Server locally

I am following this tutorial to build an AppEngine program: https://developers.google.com/appengine/docs/java/gettingstarted/setup using the terminal on mac os x 64 bit

I am having trouble getting the "guestbook" app to run on the develoment server locally. When I run the program and try to open it in my web browser it crashes a Can anyone help me solve this?

I believe due this validation error:

  [INFO] Caused by: com.google.apphosting.utils.config.AppEngineConfigException: XML errorvalidating /Users/jamesjohnson/guestbook/guestbook-ear/target/guestbook-ear-1.0-SNAPSHOT/META-INF/appengine-application.xml against /Users/jamesjohnson/.m2/repository/com/google/appengine/appengine-java-sdk/1.9.8/appengine-java-sdk/appengine-java-sdk-1.9.8/docs/appengine-application.xsd

per the instructions of the tutorial I have my build environment set to the following:

3.1.1 installed and pointed to by M2_HOME variable, running java 7 and have the JAVA_HOME variable pointing to the correct jdk, and the M2 variable set to M2_HOME/bin

I have created and configured the project exactly as the directions stated.

when I build the app I get a BUILD SUCESS message:

then when I try to run the app in the development server on my local machine by invoking this command:

mvn appengine:devserver

the server begins to run:

[INFO] <<< appengine-maven-plugin:1.9.8:devserver (default-cli) @ guestbook-ear <<<
[INFO] 
[INFO] --- appengine-maven-plugin:1.9.8:devserver (default-cli) @ guestbook-ear ---
[INFO] 
[INFO] Google App Engine Java SDK - Running Development Server
[INFO]

then I get an error message that says:

[INFO] com.google.apphosting.utils.config.AppEngineConfigException: Invalid configuration

followed by about 30 lines describing all the classes that failed. and at the end I still get a BUILD SUCCESS MESSAGE:

There is an error in your appengine-application.xml file. The code and trace you listed in your question is not related to this problem.
