Jimfs到錫蘭的路徑目錄

我想在Jimfs文件系統中創建一個目錄（使用ceylon的文件模塊），但我在從錫蘭訪問文件系統時沒有安裝Jimfs提供程序時遇到問題。Jimfs到錫蘭的路徑目錄

這是我的測試程序：

// File: test.se.gustavkarlsson.autogit.file.watcher.run 

import ceylon.file { 
    Nil, 
    parseURI 
} 

import com.google.common.jimfs { 
    Jimfs { 
     jimFs=newFileSystem 
    } 
} 

shared void run() { 
    value fs = jimFs(); 
    value jPath = fs.getPath("directory"); 
    value uri = jPath.toUri().string; 
    value path = parseURI(uri); 
    value resource = path.resource; 
    assert (is Nil resource); 
    resource.createDirectory(); 
}

運行時，打印以下堆棧跟蹤：

關於如何安裝該提供任何想法？

我在Linux上運行Ceylon 1.2.0，使用JimFs 1.0（也測試過1.1-rc1）並且使用Jimfs的「預期」方式（純java nio）可以正常工作。
