Gradle 3.0 BuildException无法创建目录

问题描述：

我在Windows上并更新到Android Studio（AS）3.0 RC1。当我尝试通过AS或终端使用gradle构建项目时，它停止，Stacktrace结束。奇怪的是，在我的同事Mac上它只是建立起来的。Gradle 3.0 BuildException无法创建目录

所以我猜路径有问题。我找不到任何关于此BuildException的具体内容。任何人都知道为什么路径看起来重复？ C:\Development\Workspace\Project\app\build\outputs\apk\Test\debug\C:\Development\Workspace\Project\app\build\outputs\apk\Test\debug

我还可以尝试解决这个问题吗？我清理，重建并重新启动了我所能做的一切。

更新我刚刚更新到3.0 RC 2，仍然得到同样的问题。

更新情况与此相同的稳定AS 3.0发行:(

随着Android Studio 3.0的稳定版本的发展，我深入了一下，结果发现我们的命名APK的脚本没有起作用，但只是在Windows上打破了。

旧脚本：

applicationVariants.all { variant -> 
    variant.outputs.each { output -> 
     def outputFile = output.outputFile 
     if (outputFile != null && outputFile.name.endsWith('.apk')) { 
      def fileName = outputFile.name.replace('.apk', "-${versionName}.apk") 
      output.outputFile = new File(outputFile.parent, fileName) 
     } 
    } 
}

固定脚本：

applicationVariants.all { variant -> 
    variant.outputs.all { 
     outputFileName = "${variant.name}-${variant.versionName}.apk" 
    } 
}

如果我想改变默认输出目录呢？ – qinxianyuzou

我试过这个解决方案，但它不工作需要帮助在这里https://stackoverflow.com/questions/48241450/android-studio-3-0-1-error-in-build-gradle –

在你gradle这个文件（模块级），您使用的applicationVariants重命名您的APK或像这样的事情？我不得不

哈哈，这是惊人的。我刚刚找到完全相同的解决方案。不管怎么说，还是要谢谢你！ –

我在Linux或Windows构建相同的应用程序与Android 3.0工作室。升级到3.0.1摇篮后，我曾在Windows类似的问题，而这是在Linux上工作正常：

Error:Execution failed for task ':smsreminder:packageDebug'. > Cannot create directory C:\Users\Florent\AndroidStudioProjects\MyApp\myapp\build\outputs\apk\debug\C:\Users\Florent\AndroidStudioProjects\MyApp\myapp\build\outputs\apk\debug

并感谢狮子座上面的回答，我做了这个更加友好的APK名称：

outputFileName = "${variant.name}-${variant.versionName}.apk" 
=> produces: debug-x.y.apk 

outputFileName = output.outputFile.name + ".${variant.versionName}.apk" 
=> produces: MyAppName.x.y.apk

否则，我发现这个工作太如果想保持默认：

if (org.gradle.internal.os.OperatingSystem.current().windows) 
      outputFileName = "${variant.name}-${variant.versionName}.apk" 
     else 
      outputFileName = new File(output.outputFile.parent, outputFileName.replace(output.outputFile.name, defaultConfig.applicationId + ".apk"))
