Jimfs path to ceylon Directory

Question

I'm trying to create a directory (using ceylon's file module) in the Jimfs file system but I'm having problems with the Jimfs provider not being installed when accessing the filesystem from ceylon.

This is my test program:

// 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();
}

When run, prints the following stacktrace:

ceylon run: Provider "jimfs" not found
java.nio.file.ProviderNotFoundException: Provider "jimfs" not found

Любые идеи о том, как установить этот поставщик?

Я использую Ceylon 1.2.0 в Linux, с JimFs 1.0 (также протестированным 1.1-rc1) и работаю с Jimfs "намеченным" способом (чистый java nio), работает отлично.

Answer 1

Это связано с видимостью модуля, где нам нужно добавить "чтение" (используя терминологию Jigsaw) из JDK в модуль jimFs.

Я открыл https://github.com/ceylon/ceylon/issues/5995 для расследования.
