maven datanucleus ASM问题

Question

在构建基于maven datanucleus的项目时，我得到了以下错误。我已经将maven-datanucleus-plugin放在plugin下，并正确定义了包含持久化类的路径。有人能帮助解决这个问题吗？

Exception in thread "Thread-1" You have selected to use ClassEnhancer "ASM" yet
the JAR for that enhancer does not seem to be in the CLASSPATH!

谢谢。

因此，您希望使用增强器，而不是按照文档将asm.jar放在类空间中。再清楚不过了。
