内容图文
我正在尝试运行一个App Engine Maven项目,并发现自己陷入了JAR地狱.该项目过去一直在不使用maven的情况下构建和运行,但是我已经足够了Eclipse的废话,并且出于所有通常的原因,试图将其进行项目化.
当前,一切正常,编译通过,测试通过(使用myproject-war目录shown here中的mvn clean install).我还可以从myproject-ear目录中启动mvn appengine：devserver并使服务器运行.导航到我的一个servlet,但是,我得到了如下所示的noSuchMethodError跟踪. (为了便于阅读,所有代码都位于底部).
这看起来类似于other posts,其中杰克逊版本未同步.但是,我的杰克逊版本似乎还可以,在pom.xml的底部也可以看到.似乎该方法didn’t appear until Jackson 3.0由于mvn依赖项的输出而再次看起来不错：tree -Dverbose | ack jackson和我依赖2.4.1的事实.
我能想到的最可能的罪魁祸首是我正在使用的google库,因为我正在关注似乎依赖它的example here.但是,我不确定如何验证该假设或如何使Google库在没有依赖的情况下工作.也许< exlcudes>标签,但我不确定如何应用.
有人对我有任何建议或遗漏吗？如何获得运行时要使用的类的正确版本？还是我错过了什么而解决方案却完全不同？
编辑：请注意,根据评论/答复的建议,我确保我负责的所有库都使用同一版本的fastxml / Jackson,而不是较旧的codehaus packaing.我同意,似乎某个地方仍然存在较旧的依赖关系会导致问题,但这恰恰是我正在努力解决的问题.
编辑2：我最终清理了整个项目和依赖项结构,尽管我无法提供确切的解决方法,但最终还是可以完成这项工作.我认为问题是由于这种依赖性造成的：
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.4.1</version>
</dependency>
它在org.jboss.resteasy：resteasy-jackson2-provider：3.0.6.Final上的has a dependency本身就是depends on com.fasterxml.jackson.core：jackson-databind：2.2.1,它没有缺少的方法,例如我在原始帖子中指出.
mvn依赖项：tree -Dverbose | ack jackson：
