Gradle3.0在未升級更新之前我們輸出apk路徑：

applicationVariants.all { variant ->
    variant.outputs.each { output ->
        def outputFile = output.outputFile
        if (outputFile != null && outputFile.name.endsWith('.apk')) {
            if(!outputFile.name.contains("debug")){
                def fileName = outputFile.name.replace(".apk"
 
, "-${defaultConfig.versionName}.apk")
                output.outputFile = new File("C:\\Users\\user\\Desktop\\apk\\${defaultConfig.versionName}", fileName)
            }
        }
    }
}

Gradle3.0升級之後我們需要更改：

程式碼如下：

applicationVariants.all { variant ->
    variant.outputs.all { output ->
        outputFileName = outputFile.name.replace(".apk"
 
, "-${defaultConfig.versionName}.apk")
        if (outputFileName != null && outputFileName.endsWith('.apk')) {
            if (!outputFile.name.contains("debug")) {
                variant.getPackageApplication().outputDirectory = new File("C:\\Users\\user\\Desktop\\apk")
                variant.getPackageApplication().outputScope.apkDatas.forEach {
                    apkData -> apkData.outputFileName = outputFileName
                }
            }
        }
    }
}
