在Google
IO中，宣布了新的构建系统gradle来替换ant。我的项目正在使用Aspectj，我想在我的项目中使用它。我无法弄清楚一些变量使其正常工作。我在那里找不到android。*输出类路径。有人可以帮忙吗？

这是我当前的build.gradle：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android'
sourceCompatibility = 1.6

configurations {
    ajc
}

dependencies {
    compile fileTree(dir: 'libs', includes: ['*.jar'])
    ajc files('build-tools/aspectjtools.jar', 'libs/aspectjrt.jar')
}

android {
    compileSdkVersion 16
    buildToolsVersion "17"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 16
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('test')
    }
}

gradle.projectsEvaluated {
    compileJava.doLast {
        tasks.compileAspectJ.execute()
    }
    println 'lalalalala'
}

task compileAspectJ {

    ant.taskdef(resource: "org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties",
        classpath: configurations.ajc.asPath)
    ant.iajc(source: sourceCompatibility, target: sourceCompatibility,
        destDir: "?????????????????????",
        classpath: "????????????????????????????") {

        sourceroots{
            android.sourceSets.main.java.srcDirs.each {
                pathelement(location: it.absolutePath)
            }  
        }  
    }  
}

这是旧的ant代码，效果很好：http：

编辑：

根据第一个答案更新了build.gradle，但是我的Iajc似乎无法识别所有库并且抱怨找不到库中的类

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'
sourceCompatibility = 1.6
targetCompatibility = 1.6

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.1.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 16
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

            }
        }
    println 'BBBBBBBBBBBBBB : ' + iajcClasspath
