Intellij + Ajc + Lombok/Mapstruct

intellij-ideaaspectjmapstructintellij-lombok-plugin

我想在我的IntelliJ Idea中启用AspectJ编译器，因为我有几个方面需要在编译时编织。
同时，我正在使用Lombok和Mapstruct在我的代码库中。
这两种工具都需要进行额外的注释处理，必须在ajc开始之前完成。我已经安装了Lombok和Mapstruct的插件。分别使用它们是可以正常工作的，源代码也被生成。但是当我启用ajc并勾选启用注释处理选项后，构建项目时会出现以下错误:

此外，我看到了其他一堆ajc编译错误，因为它无法定位应该由Lombok生成的方法。
我该如何解决这些问题？
你使用的是哪个版本的acj？你的构建工具是否有相同的问题？ - Filip

你好，我遇到过类似的问题。

解决方法是让aspectj-maven-plugin在类编译完成后才开始织入。

在此处有更详细的说明：https://www.mojohaus.org/aspectj-maven-plugin/examples/weaveDirectories.html

我需要做以下几步：

(1) 通过<weaveDirectories >指定已编译类所在的文件夹

(2) 将maven-compiler-plugin生命周期的阶段更改为“process-classes”或更晚的阶段。

这是我的pom文件的样子。

由于您提供的设置，测试未能正确编译。[错误] 方法getAList()在类型TransactionalIT.ObjectGraph中未定义 ...transactional/NestedTransactionsJdbcDao.java:26 createEntitiesA(og.getAList()); - Ihor M.
这里有什么部分是罪魁祸首的想法吗？ - Ihor M.
这是我看到的错误：Error:(18, 0) ajc: 源参数中不存在名为"contentType"的属性。你是想说"createdTime"吗？ 这是由于lombok处理器没有被调用引起的。我已经尝试过配置，但没有成功。 - Ihor M.
以下是在该错误之前出现的警告：警告：ajc：您未使用lombok支持的编译器，因此lombok将无法工作并已被禁用。 您的处理器是：org.aspectj.org.eclipse.jdt.internal.compiler.apt.dispatch.BatchProcessingEnvImpl Lombok支持：sun/apple javac 1.6、ECJ - Ihor M.

我认为在GitHub上发布一个MCVE是有意义的，这样可以让我们重现和分析你的问题。 - kriegaex
好的例子，使用了3个注解处理器：lombok、mapstruct和aspectj。我按照这里的指示进行操作，编译了来自aspectj插件和其他类似问题的信息，并且它可以正常工作。关键在于让aspectj编织生成的类，不干扰mapstruct和aspectj处理器进行代码生成。 - WinterBoot

如果您在同一项目中有方面源代码，那么您应该根据@jun-huh的答案添加几行代码，并删除<aspectLibraries>。下面的pom.xml是用于在同一项目中使用方面的情况。
