Question

环顾四周，查看此错误，看来问题出在同一个依赖项的版本不兼容。我有一个项目从另一个项目中调用一个类，因此我有两个单独的pom.xml，但它们都具有相同版本的jackson依赖关系，因此我不确定是什么导致了此错误。这是我的两个pom.xml：

分别运行每个类时，它们都按预期进行编译和运行，但是当我从类a调用b.foo（）时，标题出现错误。有什么想法吗？

Answer 1

您可以使用maven维护父模块和其他子模块的集成，并在父模块中添加依赖项，以便两个子模块都可以考虑。

Answer 2

我深入研究了一些依赖项，发现其中一个正在使用您在表面上看不到的较低版本的Jackson。因此，如果您遇到此问题并且正在使用Eclipse，请通过“依赖关系层次结构”视图查看pom.XML，您应该能够看到不兼容的来源。

是什么引起java.lang.NoSuchMethodError：com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering（）Z
