英文:
AspectJ maven plugin with annotation processor - sources are generated twice
问题
我在将AspectJ编译器插件与生成源代码的注解处理器组合时遇到了一些奇怪的行为。
我有**项目A**，这是主项目，其中包含带有注解的类。
我有**项目B**，这是依赖项目，其中包含方面类和注解处理器。
理想情况下，应该是在编译项目A时，使用项目B中的注解处理器从项目A的带注解类生成的源代码将被编译并保存在`target/generated-sources/annotations/...`目录中。
实际发生的是，在编译项目A时，源代码会生成在`target/generated-sources/annotations/...`目录中，然后在项目A的根目录中再次生成一次。
**项目A**的pom.xml：
（代码部分已省略）
**项目B**的pom.xml：
（代码部分已省略）
我找到了一个解决方法，即在AspectJ编译器的`<configuration>`下添加`<proc>none</proc>`，但这只是一个临时解决方法。我是否遗漏了什么？
我还发现了[这个问题][1]，似乎描述了类似的问题。

英文:
I'm experiencing some strange behaviour when combining the AspectJ compiler plugin with an annotation processor that generates sources.
I have Project A, the main project with annotated classes.
I have Project B, the dependency project with aspect classes and the annotation processor.
Ideally, what should happen, is upon compilation of project A, sources generated from annotated classes in Project A, using the annotation processor in project B should be compiled and saved in target/generated-sources/annotations/...
What actually happens is, upon compilation of project A, sources are generated in target/generated-sources/annotations/... and then generated a second time at the root of project A.

A workaround I found for this is to add <proc>none</proc> under <configuration> of the AspectJ compiler, but it's just a workaround. Am I missing something?
I've also found this question that seems to describe a similar issue.
