External jar dependency (migration to gradle 3.0)

Question

I've got some problems with setting dependencies to Samsung SDK and Slook libraries (Edge) after migration to gradle 3.0 plugin (3.0.0-beta6).

compileOnly fileTree(include: ['*.jar'], dir: 'libs')

If I add dependency like above, it doesn't work for API <= 19

Could not find class 'com.samsung.android.sdk.look.Slook', referenced from method (...))

compile fileTree(include: ['*.jar'], dir: 'libs')

If I add dependency like this, it doesn't work for API > 19

"com.android.build.api.transform.TransformException: java.lang.RuntimeException: java.lang.RuntimeException: java.lang.SecurityException: SHA-256 digest error for com/samsung/android/sdk/look/Slook.class"

Is it my configuration problem or maybe in Samsung SDK?

Is there any way to make it work correctly? (In code or build.gradle?)

VERSIONS:

• Android Studio 3.0 beta 6.
• Gradle plugin 3.0.0-beta6.
• sdk-v1.0.0.jar
• slook_v1.4.0.jar
