亲爱的大家：

我需要一些帮助在我的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中添加annotationProcessorPaths。xml。似乎不可能在同一pom中同时使用注释（annotationProcessorPaths和annotationProcessor）。如果我这样做了，我就会出错

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。因此，可能存在比实际需要更多的依赖关系

提前谢谢 奥利弗

Answer 1

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将只使用那些来查找注释处理器，而不是其他依赖项

或者，您也可以在annotationProcessoPaths中添加所有注释处理器，而不是添加依赖项
