j2objcTestDebug is stuck when prefixes specified

[TarasOsiris]

When executing shared:build command the build gets stuck on j2objcTestDebug command.

Successfully started process 'command '/Users/tarasleskiv/dev/repo/gs/native-sdks/sources/shared/build/j2objcTest/Debug/testJ2objc''
> Building 91% > :shared:j2objcTestDebug

Without prefixes it finishes successfully. My prefixes.properties file is

com.google.gson.* : GSON
im.getsocial.airx.* : RX
im.getsocial.airjawampa.* : JAWAMPA
im.getsocial.sdk.* : Shared

I believe something is wrong with prefixing either in j2objc-gradle

We added the prefixes.properties to tests resources and it works now, but it should fail and throw and error otherwise
