问题:

java-class存在两次(在类路径上和在应用程序jar上)。LinkageError:ClassCastException

我在启动Java应用程序时遇到以下错误。

我需要在启动应用程序之前将一些hadoop相关目录导出到类路径以使其工作(我不能跳过这一步),我正在得到以下错误。

经过一些研究,我发现程序试图使用的类存在于两个不同的JAR文件中:

>

  • 第一个是对maven应用程序(javax.ws.rs.jar)上的库的传递依赖

    第二个是位于目录中的一个jar,其中包含hortonworks的所有hadoop depdencies,我需要将这些depdencies导出到我的类路径中以使应用程序工作(jsr311-api-1.1.1.jar)

    所以我需要以某种方式告诉程序,应该使用封装在我的应用程序的jar中的maven依赖项,而不是位于类路径上的jar.(javax.ws.rs.jar),而不移除这个jar,因为它是我的大数据集群安装的一部分,我不能在类路径中玩那些jar。

    有什么想法吗?

    导致问题的pom.xml依赖项:

    我用这些版本在类路径上添加了这些jar。构建并运行。我找不到任何原因。
