Question

我尝试使用资源获取输入文件的输入内容。我为此编写了以下代码

val resourceSet = new AutosarResourceSetImpl();

var uri = URI.createFileURI(inputfilepath); 

resource = resourceSet.getResource(uri,true)

resourceSet.resources.add(resource);

在这里，如果我将输入文件放在默认工作区以外的任何文件夹中，那么它正在工作。但是如果我将输入文件放在Workspace文件夹中（默认情况下它每次都在创建），我会得到以下异常。

Answer 1

您的代码使用特殊的sphinx代码，这可能会在org.eclipse.sphinx.emf.util.EcorePlatformUtil.getFile中产生一些魔力，具体取决于您获得的URL类型。它调用WorkspaceSynchronizer.getFile表示它需要platform-resource URI。

因此，正如错误消息所示，您的网址/inputfile.arxml未遵循该方案。您需要向URL添加更多特定的工作空间相关信息，例如遵循上述平台-URI架构的插件或资源，如

platform:/plugin/org.eclipse.mybundle/inputfile.arxml

Answer 2

阅读异常，问题可能来自您表达URI的方式。

java.lang.IllegalArgumentException: Path must include project and resource name: /inputfile.arxml

如果你想使用文件URI，就像你的例子一样，你应该有：

var uri = URI.createFileURI("c:/path/to/inputfile.arxml");

您应该查看URI类的各种create方法，以便为您选择最相关的方法。

顺便说一下，在从resourceSet获取资源后，您不需要在resourceSet中添加资源...

    resource = resourceSet.getResource(uri,true)
    //resourceSet.resources.add(resource);

资源没有使用资源集
