Question

我正在关注教程http://www.javacodegeeks.com/2012/03/twitter4j-and-esper-tracking-user.html。但是当我试图编译项目时，它给了我一些错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/antlr/runtime/RecognizerSharedState
    at com.espertech.esper.epl.generated.EsperEPL2GrammarLexer.<init>(EsperEPL2GrammarLexer.java:326)

    ... 6 more

我添加了相关的jar esper-4.9.0.jar，antlr-3.0.1.jar，twitter4j-core-2.2.6.jar。请帮助我解决错误，因为我已经做了很多谷歌但是没有找到解决方案。

Answer 1

antlr-runtime-3.2.jar是正确的jar（删除antlr）

Twitter4j和Esper：在主java.lang.NoClassDefFoundError上抛出错误
