Question

我正在使用AspectJ来处理我正在进行的项目。作为项目的一部分，我试图使用“maven-shade-plugin”和“jarjar-maven-plugin”，以便将类从一个jar重新定位到另一个jar。

在这两种情况下，当我尝试使用生成的JAR时，AspectJ失败并出现以下异常：

如果你能指出我做错了什么，我将不胜感激。

谢谢， Nadav

Answer 1

最后我没有使用maven-jarjar-plugin和maven-shade插件。我已经使用了JarJar的JAR本身，这解决了这个问题（因为它在编译期间没有用AspectJ修改JAR）。

以下问题的答案描述了解决方案：

Relocating fastxml.jackson classes to my.package.fastxml.jackson

类重定位后，Aspectj抛出“org.aspectj.weaver.BCException：malformed org.aspectj.weaver.PointcutDeclaration attribute”异常
