Universal App - Can't find resources

[robgraeber]

Hey I'm having issues getting access to resource files after packaging. It seems like getResource can't find the root of the Jar for some reason.

For example, before packaging:

getClass.getResource("/").getPath -> /Users/****/example-proj/target/scala-2.11/classes/
getClass.getResource("").getPath -> /Users/****/example-proj/target/scala-2.11/classes/com/example/foo/
getClass.getClassLoader.getResource("/").getPath -> java.lang.NullPointerException
getClass.getClassLoader.getResource("").getPath -> /Users/****/example-proj/target/scala-2.11/classes/

And after packaging:

getClass.getResource("/").getPath -> java.lang.NullPointerException
getClass.getResource("").getPath -> file:/Users/****/example-proj/target/universal/stage/lib/default.example-proj-1.0.jar!/com/example/foo/
getClass.getClassLoader.getResource("/").getPath -> java.lang.NullPointerException
getClass.getClassLoader.getResource("").getPath -> java.lang.NullPointerException

I opened up the example-proj-1.0.jar and all the resources are there. Is there something I'm missing? I read some stack overflow threads about maybe adding Class-Path: . to the manifest.mf.

I guess you resolved this on your own. This is not related to native-packager, but the java NIO Path implementation.

Yeah I figured it out. It was because I was iterating over the files in a directory, but that doesn't work with JARs. I ended up writing a helper function that checks if the code is inside of a JAR or not, and iterates appropriately.
