Build issue with the Google Docs Java API

I'm trying to get some google docs functionality going and I've decided to do the basic tutorial they provide here

I followed their instructions to the T but got the following error when I tried to run:

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/Maps
    at com.google.gdata.wireformats.AltRegistry.<init>(AltRegistry.java:118)

Caused by: java.lang.ClassNotFoundException: com.google.common.collect.Maps

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
    ... 4 more

I double checked that I had all of the dependencies that were required in my build path, and I know they are recognized in my project because the IDE isn't complaining when I instantiate objects from the referenced API's.

Any help would be appreciated.

Solution

  • I was missing the following Jar which is apparently needed but not mentioned in the tutorial.

    deps/google-collect-1.0-rc1.jar
