apache spark - Unresolved dependency with xgboost library in scala -


this question has answer here:

i've added xgboost jar files in library , modules in project structure. (i built jar files source mentioned in documentation). can't seem able resolve dependency it. i've tried run dependency included in build sbt file , taken out (since jars included in library , dependencies via project structure). both seem failing. sort of compatibility issue? running scala 2.11.8 , spark 2.1.0. dependencies included in sequence follows: 

"ml.dmlc" %% "xgboost4j" % "0.7", "ml.dmlc" %% "xgboost4j-spark" % "0.7"

i seem missing not sure what. ideas?

i tried publish jar suggested following error:

the dependency should have 1 % there. 

"ml.dmlc" % "xgboost4j" % "0.7", "ml.dmlc" % "xgboost4j-spark" % "0.7"

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
