This is because URI instances cannot contain spaces, and the following code is used to translate this jar path into a URI:

uri = new URI( url.toString() ); //DefaultMavenProjectBuilder.readModel(String, URL, boolean): Model (revId: 587777)

Changed:

new URI( url.toString() );

to:

new URI( url.toString().replaceAll( " ", "%20" );

which should fix the most common problem related to paths (i.e. paths with spaces in them)

For more info

I was using the URL.toURI method but it's only available in java 5
http://java.sun.com/javase/6/docs/api/java/net/URL.html#toURI()

"This method functions in the same way as new URI (this.toString()).
Note, any URL instance that complies with RFC 2396 can be converted to a URI. However, some URLs that are not strictly in compliance can not be converted to a URI."
