Josh,
This line:
java.lang.NoClassDefFoundError: Could not initialize
class com.google.gdata.client.http.GoogleGDataRequest
Tells me that the issue is with your build environment not being able to
resolve these files. Including JAR files in your lib directory ensures that
classes in these JAR files will be resolved when the application is deployed
to App Engine, however, it does not mean that it will necessarily work in
your local environment. The JAR files may be in your classpath, but if you
are using an IDE, the IDE may override the default CLASSPATH variable for
your system. The safest thing to do is to go into your IDE settings and make
sure that the JAR files are being included in your build. Can you give that
a try and let us know what happens?
