Android新构建系统(gradle)和aspectj

Lib*_*rty 17 java android gradle

在Google IO中,新的构建系统gradle宣布取代ant.我的项目是使用aspectj,我想在我的项目中使用它.我无法找出一些变量来使它工作.我没有找到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)
            }  
        }  
    }

根据第一个答案更新了build.gradle.但是我认为iajc似乎没有识别出所有库并抱怨库中的类没有找到

        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

我也想使用带有gradle和Android Studio的aspectj,我终于得到了它的工作,但我仍然有一些手写的路径,我想用更通用的gradle选项替换.

编辑:我用基于gradle的替代方法替换了每个硬编码的绝对路径,因此该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,可以从IDE更改为其他版本或Android Studio的其他版本.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}",

                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},它都将根据当前的构建配置由"debug"或"release"替换.

将android.jar添加到类路径是编译Android特定类所必需的,并且该行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:对构建iajcClasspath的项目依赖项的迭代允许您使用库项目中的类.configurations.compile.asPath已经包含对你的apklib(aar文件)的引用,它实际上是一个包含jar和库资源的zip.Iajc不识别这些文件,但是在build目录下有一个包含classes.jar的包目录.我使用了一个带有"release"硬编码的相对路径,因为在我的情况下,库与主项目有不同的变体,所以我不能${variant.dirName}在这里使用.

  • 我有关于库的使用的相同问题,我认为将库项目添加到iajc类路径就足够了,但似乎已经在其中:`println configurations.compile.asPath`显示以`开头的路径`在我的情况下/ home/aegar/AndroidStudioProjects/AopProject/LibTest/build/libs/LibTest.aar`,所以我认为问题是iajc不能识别aar库. (2认同)
  • @withoutclass:iajc现在识别我的库,我更新了答案.我希望它也适合你. (2认同)

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.以下代码将执行此操作.

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

所以整个部分将是:

    // 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
