亲爱的，

我需要一些帮助来在我的 project 中实现 mapstruct。我已经有一些注释处理器需要在 Maven 的 pom.xml 中命名。 Mapstruct建议在pom.xml中添加annotationProcessorPaths。似乎不可能在同一个 pom.xml 中同时使用两个注释（annotationProcessorPaths 和 annotationProcessor）。如果这样做，我会得到错误

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default) on project yyy-data: Compilation failure [ERROR] Annotation processor 'de.zzz.annotation.processor.GenerateHibernateTypeForEnumProcessor' not found

我确实缩短了 pom。所以依赖项可能比实际需要的多。

提前致谢奥利弗

您仍然可以使用 annotationProcessor。您需要在依赖项中添加 mapstruct-processor，然后在 annotationProcessor.

中添加 org.mapstruct.ap.MappingProcessor

您看到错误的原因是，当您定义 annotationProcessorPaths 时，maven-compiler-plugin 将仅使用那些来查找注释处理器，而不是您的其他依赖项。

或者，如果您的依赖项，您也可以添加 annotationProcessoPaths 中的所有注释处理器。
