I got this error when I tried to run one of my apps after upgrading to RoboGuice 2.0. Whilst I do love RoboGuice and appreciate the hard work of the contributors, the project’s documentation has not had the same attention as the code.
To get things working you’ll need to add another jar in addition to roboguice2 and guice3(no aop). The new jar is “javax.inject.jar” and you can extract it from the zip distribution of Guice 3.0. After adding the new jar just add it to your libs folder as normal and try running your app again.
