在 Google IO 中,宣布新的构建系统 gradle 将取代 ant。我的项目正在使用 aspectj,我想在我的项目中使用它。我想不出一些变量来让它工作。我在那里找不到 android.* 输出类路径。任何人都可以帮忙吗?

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)
            }  
        }  
    }  
}

我还想将 aspectj 与 gradle 和 Android Studio 一起使用,我终于让它工作了,但我仍然有一些我想用更通用的 gradle 选项替换的手写路径。

编辑:我用基于 gradle 的替代方案替换了每个硬编码的绝对路径,所以这个解决方案不再依赖于给定的平台或用户名。但是,它仍然使用相对路径,这些路径可能会从 IDE 更改为其他 IDE 或 Android Studio 的后续版本。另外,我对找到 android.jar 的方式并不满意。

我首先加载aspectj:

configurations {
ajc
aspects
ajInpath
}

ext.aspectjVersion = '1.7.3'

dependencies {
    compile project(":LibTest")

    ajc "org.aspectj:aspectjtools:${aspectjVersion}"
    compile "org.aspectj:aspectjrt:${aspectjVersion}"
    compile 'com.android.support:appcompat-v7:18.0.0'
}

然后我添加一个将在当前变体的 JavaCompile 任务之后运行的任务:

android.applicationVariants.all { variant ->

    variant.javaCompile.doLast {
        def androidSdk = android.adbExe.parent + "/../platforms/" + android.compileSdkVersion + "/android.jar"

        def iajcClasspath = configurations.compile.asPath + ";" + androidSdk
        configurations.compile.dependencies.each { dep ->
            if(dep.hasProperty("dependencyProject")) {
                iajcClasspath += ":" + dep.dependencyProject.buildDir + "/bundles/release/classes.jar"
            }
        }

        ant.taskdef( resource:"org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties", classpath: configurations.ajc.asPath)
        ant.iajc (
                source:sourceCompatibility,
                target:targetCompatibility,
                destDir:"${project.buildDir}/classes/${variant.dirName}",
                maxmem:"512m",
                fork:"true",
                aspectPath:configurations.aspects.asPath,
                inpath:configurations.ajInpath.asPath,
                sourceRootCopyFilter:"**/.svn/*,**/*.java",
                classpath:iajcClasspath
        ){
            sourceroots{
                android.sourceSets.main.java.srcDirs.each{
                    pathelement(location:it.absolutePath)
                }
                pathelement(location:"${project.buildDir}/source/r/${variant.dirName}")
            }
        }
    }
}

无论我在哪里使用${variant.dirName},它都会根据当前的构建配置替换为“调试”或“发布”。

需要将 android.jar 添加到类路径以编译 Android 特定的类,并且pathelement(location:"${project.buildDir}/source/r/${variant.dirName}")需要使用自动生成的 R.java 文件中的类。

编辑:对项目依赖项的迭代以构建 iajcClasspath 允许您使用库项目中的类。configurations.compile.asPath已经包含对您的 apklib(aar 文件)的引用,它实际上是一个包含 jar 和库资源的 zip。Iajc 无法识别这些文件,但在 build 目录下有一个包含您的库的 classes.jar 的 bundle 目录。我使用其中硬编码“发布”的相对路径,因为在我的情况下,该库的变体与主项目不同,所以我不能${variant.dirName}在这里使用。

这是完整的 build.gradle 文件:

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

我发现 AAR 不能在我的代码中用作 jar 库。如果您使用这样的依赖项

compile 'com.android.support:appcompat-v7:18.0.0'

您需要找到 jar 文件并添加到类路径中。下面的代码将做到这一点。

tree = fileTree(dir: "${project.buildDir}/exploded-bundles", include: '**/classes.jar')
tree.each { jarFile ->
    iajcClasspath += ":" + jarFile
}

所以整个部分将是:

variant.javaCompile.doLast {
    // Find the android.jar and add to iajc classpath
    def androidSdk = android.adbExe.parent + "/../platforms/" + android.compileSdkVersion + "/android.jar"
    println 'Android SDK android.jar path: ' + androidSdk

    def iajcClasspath = androidSdk + ":" + configurations.compile.asPath
    configurations.compile.dependencies.each { dep ->
        if(dep.hasProperty("dependencyProject")) {
            iajcClasspath += ":" + dep.dependencyProject.buildDir + "/bundles/release/classes.jar"
        }
    }

    // handle aar dependencies pulled in by gradle (Android support library and etc)
    tree = fileTree(dir: "${project.buildDir}/exploded-bundles", include: '**/classes.jar')
    tree.each { jarFile ->
        iajcClasspath += ":" + jarFile
    }
        println 'Classpath for iajc: ' + iajcClasspath

        ant.taskdef( resource:"org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties", classpath: configurations.ajc.asPath)

有关完整示例,请在此处查看 AnyMemo 项目的 build.gradle: https ://code.google.com/p/anymemo/source/browse/build.gradle?spec=svnf85aaa4b2d78c62876d0e1f6c3e28252bf03f820&r=f85aaa4b2d78c62876d0e1f6c3e28252bf03f28

尽管以前的答案脚本适用于大多数情况,但它们并未涵盖将 Android 与 AspectJ 和 Gradle 一起使用的一些问题。

我的测试是创建一个库项目,任何人都应该通过 mavenCentral 或我将其用作参考库项目和测试应用程序项目。库项目是具有所有方面的项目,应用程序测试试图使用这些方面。以此为背景,最终的项目结构为:

HEAD-Gradle
---LibraryProject
-------SomeAspects
---TestApplication
-------Uses-SomeAspects

我发现使它起作用的解决方案是:

1- 对于图书馆项目,您必须使用

libraryVariants.all { variant -> 

代替

android.applicationVariants.all { variant ->

2- 为 Android 的 19.+ 构建工具更改了构建目录,因此正如一条评论中所建议的(感谢“WithoutClass”),您必须在树变量中使用 exploded-aar 目录而不是 exploded-bundles 目录定义。从:

def tree = fileTree(dir: "${project.buildDir}/exploded-bundles", include: '**/classes.jar')

至:

def tree = fileTree(dir: "${project.buildDir}/exploded-aar", include: '**/classes.jar')

3-我在进行集成时遇到的最后一个问题是,如果您有一个库项目,则在子项目中找不到在其上定义的方面。要解决这个问题,您必须将自定义库的 classes.jar 添加到 aspectJ 编译器配置中。您可以通过添加依赖项来实现此目的:

aspects project(":YourLibraryProject")

并且还需要对本文最后提供的脚本进行一些更改。

现在,我能想象到的最好的脚本甚至可以使用库项目为 aspectj 提供全面支持:

对于依赖项:

configurations {
    ajc
    aspects
    ajInpath
}

//Version of aspectj
def aspectjVersion = '1.8.+'
// The dependencies for this project
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    //Your dependencies to a custom library project
    compile project(":YourLibraryProject")
    aspects project(":YourLibraryProject")
    //Aspectj dependencies
    ajc "org.aspectj:aspectjtools:${aspectjVersion}"
    compile "org.aspectj:aspectjrt:${aspectjVersion}"
}

编译器运行脚本

android.applicationVariants.all { variant ->

variant.javaCompile.doLast {
    // Find the android.jar and add to iajc classpath
    def androidSdk = android.adbExe.parent + "/../platforms/" + android.compileSdkVersion + "/android.jar"

    def iajcClasspath = androidSdk + ":" + configurations.compile.asPath
    //This line and the fordward assignations allow the aspects support in the child project from the library project
    def customAspectsPath = configurations.aspects.asPath
    configurations.compile.dependencies.each { dep ->
        if(dep.hasProperty("dependencyProject")) {
            iajcClasspath += ":" + dep.dependencyProject.buildDir + "/bundles/${variant.buildType.name}/classes.jar"
            customAspectsPath += ":" + dep.dependencyProject.buildDir + "/bundles/${variant.buildType.name}/classes.jar"
        }
    }

    // handle aar dependencies pulled in by gradle (Android support library and etc)

    def tree = fileTree(dir: "${project.buildDir}/exploded-aar", include: '**/classes.jar')
    tree.each { jarFile ->
        iajcClasspath += ":" + jarFile
    }

    ant.taskdef( resource:"org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties", classpath: configurations.ajc.asPath)
    ant.iajc (
            source:sourceCompatibility,
            target:targetCompatibility,
            destDir:"${project.buildDir}/classes/${variant.dirName}",
            maxmem:"512m",
            fork:"true",
            aspectPath:customAspectsPath,
            inpath:configurations.ajInpath.asPath,
            sourceRootCopyFilter:"**/.svn/*,**/*.java",
            classpath:iajcClasspath
    ){
        sourceroots{
            android.sourceSets.main.java.srcDirs.each{
                pathelement(location:it.absolutePath)
            }
            pathelement(location:"${project.buildDir}/source/r/${variant.dirName}")
        }
    }
}
}

请记住,如果您想在库子项目上运行 AspectJ,您还必须在库的 build.gradle 上拥有此脚本。

在使用Android Studio 0.8或以上的情况下,使用gradle 0.12.+似乎是必要的。

在 gradle 0.12.+ 中,exploded aar 是在 build 文件夹中提取的,而不是在 exploded-aar 文件夹中。

因此,为了处理 aar 依赖项,您必须使用以下代码:

tree = fileTree(dir: "${project.buildDir}", include: '**/classes.jar')
tree.each { jarFile ->
    iajcClasspath += ":" + jarFile
}
