Tapestry error: The resource path was not within an aliased path

I am not a Java developer and forced to work with Tapestry 5.3.8. I am able to use assets like css, images and a fav icon in my web page. I do this by injecting them in my page like this:

@Inject
@Path("context:static/img/logo.png")
private Asset logo;

@Inject
@Path("context:static/img/favicon.ico")
private Asset favIcon;

This works without problems. Although it works, I am not convinced the assets are in the right folder. Should they be placed in folder 'static'?

Now I want to add a Javascript file. This is what I did:

@Import(library = "context:static/js/additional.js")
public class Master {
// ...
}

The file is found, but I runtime i get the following error: "The resource path was not within an aliased path".

From what I understand is that I need to create an alias for the path where my Javscript file is located, but how?

I guess this must be done in method "contributeClasspathAssetAliasManager" in CiAppModule.java. Is this right, and what should I add?

The problem was in this part:

@Import(library = "context:static/js/additional.js")

When I change it into

@Import(library = {"context:static/js/additional.js"})

it works.

Thanks to Tapestry's error reporting, this was not clear at all. Grrrr.

I've never tried to use a context: asset for a javascript file. Tapestry makes classpath assets available under the assets/ alias which is possibly what this error is referring to. See the mention of 'asset fingerprinting' here

A possible souition is:

package foo.bar.components;

@Import(library = "additional.js")
public class Master {

And then have foo/bar/components/additional.js available on the classpath. For maven / gradle this will mean the file lives at src/main/resources/foo/bar/components/additional.js
