gradle学习之——自定义task

自定义task任务，实现productFlavors中不同flavor的自动打包。代码如下：

flavors.keySet().each { flavor ->
    buildTypes.each { buildType ->
        def flavorCNName = getFlavorCNName(flavor)
        tasks.create(name: "打包-" + "$flavorCNName" + "-${buildType}") {
            group groupName
            def flavorFirst = flavor.subSequence(0, 1)
            def flavorRemainder = flavor.subSequence(1, flavor.length())
            def buildTypeFirst = buildType.subSequence(0, 1)
            def buildTypeRemainder = buildType.subSequence(1, buildType.length())
            dependsOn "assemble${flavorFirst.toUpperCase()}${flavorRemainder}${buildTypeFirst.toUpperCase()}${buildTypeRemainder}"
            doLast {
                def fromPath = buildDir + "/outputs/apk/${flavor}/${buildType}"
                def toPath = "$distDir/$flavorCNName/${buildType}"
                println("fromPath:$fromPath")
                println("distDir:$distDir")
                println("toPath:$toPath")
                copy {
                    from(fromPath)
                    into(toPath)
                    include(*.apk)
                }
            }
        }
    }
}
