Richard Bolkey commented on ETCH-69:
------------------------------------

I had run into this issue as well.  Forget exactly what I discovered, but I seem to recall that URLClassLoader being passed into Etch from Maven not being all that friendly (or something like that ... it's a little fuzzy).  I do remember the work around I used though.  

In your settings.xml file, set your local repository path to "c:\docume~1\<username>\.m2\repository

> While trying to write a maven POM that executes the etch task via the antrun plugin, I discovered EtchCompiler throwing an exception if the path to the etch jars contains spaces. This resulted from my M2 repository being located in c:\Documents and Settings\brian\.m2\repository. The output is:

> The documentation for URL.toURI() says that it cannot produce a URI if the URL is not RFC 2396 compliant. Using a multi-arg constructor for URI fixes the problem. In EtchCompiler.java, replace line 222 with:
>                     String scheme = "file";
>                     int pathBegin = scheme.length() + 1;
>                     String path = s.substring(pathBegin);
>                     // multi-arg constructor properly escapes paths
>                     File f = new File(new URI(scheme, null, path, null));
