I'm following a tutorial http://www.javacodegeeks.com/2012/03/twitter4j-and-esper-tracking-user.html. But when I'm trying to compile the project it gives me follwoing error:

I have added the relevant jars esper-4.9.0.jar, antlr-3.0.1.jar, twitter4j-core-2.2.6.jar. Please help me in resolving errors as I have done lot of google but there is as such no solution found.

Answer 1

antlr-runtime-3.2.jar is the right jar (remove antlr)
