Unresolved reference: last_fm_api_key

[deephole]

I'm trying to build this via ./gradlew clean build and I'm getting following error : `Download https://dl.google.com/dl/android/maven2/com/android/support/support-annotations/27.0.2/support-annotations-27.0.2.jar Download https://jcenter.bintray.com/com/google/code/gson/gson/2.7/gson-2.7.jar Download https://jcenter.bintray.com/org/jetbrains/anko/anko-sdk15/0.10.4/anko-sdk15-0.10.4.jar Download https://jcenter.bintray.com/org/jetbrains/anko/anko-design/0.10.4/anko-design-0.10.4.jar Download https://dl.google.com/dl/android/maven2/android/arch/lifecycle/common/1.0.3/common-1.0.3.jar e: /Users/plasta/Desktop/Bandhook-Kotlin-master/app/src/main/java/com/antonioleiva/bandhookkotlin/di/DataModule.kt: (28, 100): Unresolved reference: last_fm_api_key

As @antoniolg specifies in the readme.MD, you need to add your own key:

https://github.com/antoniolg/Bandhook-Kotlin/#how-to-use-this-project

You should go to http://www.lastfm.es/api and create this file with this content: <string name="last_fm_api_key">YOUR_KEY</string> in this route app/src/main/res/values/api_key.xml.

Hope it helps!
