How to Get Project Path and File Path in a Remote Environment for a Plugin

Hi,

Regarding the main project path, there is no such concept. A project can consist of multiple modules located in different locations. Please describe your use case - why do you need a project path?

Regarding file path - why do you retrieve it via getPresentableName? What does file.getPath return in both cases?

Thanks for your reply.

I need to retrieve the project path because I want the plugin to call another program, and this program takes the project path as a parameter. Alternatively, it doesn’t necessarily have to be called the project path—it could just be the root folder path of the folder opened in the IDE.

Regarding retrieving the path, I referred to the implementation of `CopyPathsAction`. In this implementation, the `getPaths` method uses the `getPresentableUrl` method. However, I’ve also looked into the implementation of `getPresentableUrl`, which ultimately relies on `getPath`. What I actually need is just the return value of `getPath`.

The problem arises in remote mode because the specific implementation class of `VirtualFile` is `ThinClientNodeVirtualFile`. In this class, the implementation of `getPath` is defined in `LightVirtualFileBase`. Here, the return value of `getPath` depends on `getParent`, but the `parent` is defined as `null`, which means it will always return `/filename`.

// LightVirtualFileBase
public VirtualFile getParent() {
   return null;
}

public @NotNull String getPath() {
   VirtualFile parent = this.getParent();
   String var10000 = (parent == null ? "" : parent.getPath()) + "/" + this.getName();
   if (var10000 == null) {
       $$$reportNull$$$0(1);
   }

   return var10000;
}

I would like to emphasize that what you see in the project view doesn't have to be a single opened directory. A project can contain multiple modules, which consist of roots located in various directories. You shouldn't assume that the project is just a single directory. I understand that in your case, you can simplify the use case, if there is a strict convention of locating a project in a single directory, but I wanted to make it clear.

Anyway, this question is more about getting a path of a file, as far as I understand. I asked my colleagues responsible for remote development features. Please be patient.

Hello Xuxin3101 !

Could you please provide a bit more detail about the place where you're trying to get a project path? Is it an action, a startup activity, an extension or something else?

For instance, if we're talking about CopyPathsAction, it is executed on the backend, so the actual VirtualFile with the correct parent will be used. However, based on your description, it seems your code is being called on the frontend, right?
