问题描述：

我发展与杰克逊软件，但完全被卡住......当我与java -jar <MY_APPLICATION>.jar命令运行弹簧引导程序，我得到了以下错误：杰克逊抛出IllegalAccessError即使采用相同的版本

错误以上有更多的错误信息，但我认为重要的信息是，我知道它通常不会发生。

我证实，杰克逊的模块在同一个版本（2.6.5这来自春天启动的依赖），并Codehaus的的杰克逊不包括：

$ mvn dependency:tree -Dverbose -Dincluces=com.fasterxml.jackson.core | grep -v omitted 

...

任何人都可以遇到这样的问题？任何人都可以提出任何解决方案或可能性的错误？先谢谢你。

我找到了原因。

该依赖关系包括calcite-avartica工件，并且其版本2.1.1中包含阴影杰克逊。这就是为什么我找不到mvn dependency:tree的依赖关系。我通过查看StdSerializer来自哪里进行远程调试。 https://issues.apache.org/jira/browse/CALCITE-1110

Avartica 1.9.0或更高版本可能不会打扰我们。我只是排除了calcite-core和calcite-avartica，最后它工作正常。
