maven中同时使用aspectj和lombok

参考：https://palesz.wordpress.com/2011/12/03/howto-maven-lombok-and-aspectj-together/

keypoint 是让 aspectj 更改class文件，而不是更改java代码。

最终要添加的配置是：

<forceAjcCompile>true</forceAjcCompile>
<sources/>
<weaveDirectories>
    <weaveDirectory>${project.build.directory}/classes</weaveDirectory>
</weaveDirectories>

完整的plugin设置阔以参考：

有compiler插件是因为同时还有别的注解（mapstruct）需要处理。

不过还是有一些问题，如

maven shade jar 参考

这时候最好单独起项目，如果作为模块包含在别的项目里面，最终打包可能是成功的，但会导致idea等IDE找不到符号。

单独建立项目时，使用一个 pom.xml 即可，相关内容可以参考下面的实例（shaded guava和asynchttpclient）
