折腾了几天，网上的一些文章会有点old，大部分是不能用的，比如hujiang，及其issue中的维护版本也是不行，编译会报错。

AOP基础->点击前往

已验证可行的流程如下

// 首先在根工程下的
dependencies {
  classpath 'org.aspectj:aspectjtools:1.9.7'
  classpath 'org.aspectj:aspectjweaver:1.9.7'
  ...
}

// 在app的build.gradle
android {
  ...
}

dependencies {
  implementation( 'org.aspectj:aspectjrt:1.9.7' )
  ...
}

AOP生效，与android同级
//使得aop生效
import org.aspectj.bridge.IMessage
import org.aspectj.bridge.MessageHandler
import org.aspectj.tools.ajc.Main

// 获取log打印工具和构建配置
final def log = project.logger
final def variants = project.android.applicationVariants
variants.all { variant ->
    if (!variant.buildType.isDebuggable()) {
        // 判断是否debug，如果打release把return去掉就可以
        log.debug("Skipping non-debuggable build type '${variant.buildType.name}'.")
        // return;
    }
    // 使aspectj配置生效
    JavaCompile javaCompile = variant.javaCompile
    javaCompile.doLast {
        String[] args = ["-showWeaveInfo",
                         "-1.8",
                         "-inpath", javaCompile.destinationDir.toString(),
                         "-aspectpath", javaCompile.classpath.asPath,
                         "-d", javaCompile.destinationDir.toString(),
                         "-classpath", javaCompile.classpath.asPath,
                         "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)]
        log.debug "ajc args: " + Arrays.toString(args)

        MessageHandler handler = new MessageHandler(true);
        new Main().run(args, handler);
        //在编译时打印信息如警告、error等等
        for (IMessage message : handler.getMessages(null, true)) {
            switch (message.getKind()) {
                case IMessage.ABORT:
                case IMessage.ERROR:
                case IMessage.FAIL:
                    log.error message.message, message.thrown
                    break;
                case IMessage.WARNING:
                    log.warn message.message, message.thrown
                    break;
                case IMessage.INFO:
                    log.info message.message, message.thrown
                    break;
                case IMessage.DEBUG:
                    log.debug message.message, message.thrown
                    break;
            }
        }
    }
}
