“project.copy”不适用于MacOS High Sierra

问题描述：

在我的Android Studio项目中，我有一个小脚本，它可以从不同的Language Resources创建，Android为strings.xml，iOS为.lproj。“project.copy”不适用于MacOS High Sierra

到目前为止，一切正常，但后来我升级到MacOS高塞拉利昂。现在在我的Android Studio项目中，创建我的字符串值的gradle-Task失败，因此无法在将string.xml移动到res/文件夹时打开values-da文件夹。

它失败的部分是在这里：

project.fileTree(dir: scriptPath).visit { 
    FileVisitDetails details -> 
     if (details.file.name.startsWith("values-")) { 
      println "copying " + details.file.absolutePath + " to " + resPath; 
      //It fails here at .copy 
      project.copy { 
       from details.file.absolutePath 
       into resPath + "/" + details.file.name 
       // copy english resources to base values folder 
       if (details.file.name.equals("values-en")) { 
        into resPath + "/values" 
       } 
      } 

      details.file.deleteDir(); 
     } 
}

我的第一个猜测是，这可能与新的文件系统。有没有人有类似的问题？我可以证实我可能是由高塞拉引起的，因为我的同事在更新到高塞拉之后也有同样的问题。

这里的“出了什么问题” -Message：

A problem occurred evaluating project ':app'.

这里是堆栈跟踪，同时用--stacktrace运行任务我：

答

我能解决我的问题，一个小的变化。在发布我见过的堆栈跟踪之后，JDK7FileProvider的“.postVisitDirectory”方法抛出错误。

文档说，在FileTree中访问后，总是调用此方法。于是我将删除操作从当前访问中移出并放入.visit{}后面的关闭中，然后再次编译。

下面的代码：

List<File> dirsToDelete = new ArrayList<File>() 
// copy string resources from shared 
project.fileTree(dir: scriptPath).visit { 
    FileVisitDetails details -> 
     if (details.file.name.startsWith("values-")) { 
      println "copying " + details.file.absolutePath + " to " + resPath; 
       project.copy { 
        from details.file.absolutePath 
        into resPath + "/" + details.file.name 
        // copy english resources to base values folder 
        if (details.file.name.equals("values-en")) { 
         into resPath + "/values" 
        } 
        dirsToDelete.add(details.file) 
      } 
     } 
}.with { 
    for(Iterator<File> i = dirsToDelete.iterator(); i.hasNext();) { 
     File file = i.next(); 
     file.deleteDir(); 
    } 
}

“project.copy”不适用于MacOS High Sierra
