> We're using Java's SPI mechanism to load implementations at runtime. To be exact, the iface jar looks for a particular file (using ClassLoader.getResource) when the application starts, and reads inside of it to find out what the real implementation is. Then, it uses reflection (ClassLoader.loadClass) to actually load the class.
> This mechanism works like a dream in Eclipse, JUnit, etc, but fails mysteriously in Maven 2. I say mysteriously, because it locates the file in the impl jar, but then can't manage to load the class inside that jar! Snippets from my build log... sorry for the redacting, but it's not open-source code being built...

> Any insights into what's going on here? This seems tremendously broken...
