1.新建一个plugin：
import com.android.build.gradle.AppPluginimport com.android.build.gradle.LibraryPluginimport org.aspectj.bridge.IMessageimport org.aspectj.bridge.MessageHandlerimport org.aspectj.tools.ajc.Mainimport org.gradle.api.Pluginimport org.gradle.api.Projectimport org.gradle.api.tasks.compile.JavaCompileclass AspectJPlugin implements Plugin { @Override void apply(Project project) { def hasApp = project.plugins.withType(AppPlugin) def hasLib = project.plugins.withType(LibraryPlugin) if (!hasApp && !hasLib) { throw new IllegalStateException("'android' or 'android-library' plugin required.") } final def log = project.logger final def variants if (hasApp) { variants = project.android.applicationVariants } else { variants = project.android.libraryVariants } project.dependencies { // TODO this should come transitively debugCompile 'org.aspectj:aspectjrt:1.8.6' //app 运行时需要aspectjrt } variants.all { variant -> JavaCompile javaCompile = variant.javaCompile javaCompile.doLast { String[] args = [ "-showWeaveInfo", "-1.5", "-inpath", javaCompile.destinationDir.toString(), "-aspectpath", javaCompile.classpath.asPath, "-d", javaCompile.destinationDir.toString(), "-classpath", javaCompile.classpath.asPath, "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator) ] log.lifecycle "ajc args: " + Arrays.toString(args) MessageHandler handler = new MessageHandler(true); new Main().run(args, handler); 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; } } } } }} 在每个variant的JavaCompile Task加入aspectj的运行代码：
new Main().run(args, handler);运行aspectJ的参数如下：
String[] args = [ "-showWeaveInfo", "-1.5", "-inpath", javaCompile.destinationDir.toString(), //class的输出目录，作为aspectJ的输入，如 -inpath, D:\work\code\MaterializeYourApp\app\build\intermediates\classes\debug，切面定义文件可以在源文件里定义 "-aspectpath", javaCompile.classpath.asPath, //依赖的jar包，切面定义文件可以在包含在第三方依赖中 "-d", javaCompile.destinationDir.toString(), //输出class的目录 "-classpath", javaCompile.classpath.asPath, //依赖的jar包 "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator) //-bootclasspath, C:\Users\yangwei-os\AppData\Local\Android\Sdk\platforms\android-25\android.jar ]2. apply plugin: AspectJPlugin
3. 如果切面文件定义在源文件中，需要在工程的build.gradle中加入
