# http4k

[Andrew O'Hara]

Has anyone ever used proguard with http4k? I have shrinking and optimizing working, but obfuscating causes issues with the static router. It calls the loadMetaResource function, which looks up a resource in the META-INF folder based on the calling class name.

Unfortunately, since the class name is obfuscated and the resource paths are not, the mime.types file cannot be found.

[Andrew O'Hara]

I suspect (but don't know) that if the mime.types wasn't put in META-INF, the path structure would have been obfuscated consistently with the class file, and this issue wouldn't occur.

Is there a particular reason for putting mime.types in META-INF?

It's been a while... I can't remember why it's there (my knowledge of the meta inf folder is patchy)

[dave]

But that is also where the webjars put their files so it's not just static resources which would be affected

[Andrew O'Hara]

I'm not convinced there's any need to obfuscate library classes anyway, so maybe I can add an exception

[James Richardson]

So... there are lots of options in proguard to rename things based on the obfuscation, or to get the output mapping file and rename resources based on that etc. It is a pretty deep rabbit hole. If there is no need to rename things it does make it easier.
