What steps will reproduce the problem? 1. use scala 2.10.0 2. with JDK 7

now run:

scala> import com.google.gdata.calendar._ import com.google.gdata.calendar._

scala> val service = new CalendarService("statocal") service: com.google.gdata.calendar.CalendarService = com.google.gdata.calendar.CalendarService@68e8e754

scala> service.setUserCredentials("robin@wenglewski.de", "Invictus99") java.lang.NoSuchMethodError: scala.collection.JavaConversions$.asMap(Ljava/util/Map;)Lscala/collection/mutable/Map; at com.google.gdata.client.HttpConnection$HttpResponse.headers(HttpConnection.scala:215) at com.google.gdata.client.ClientLoginFactory.getToken(ClientLoginFactory.scala:104) at com.google.gdata.client.ClientLoginFactory.setUserCredentials(ClientLoginFactory.scala:59) at com.google.gdata.Service.setUserCredentials(Service.scala:62) at .<init>(<console>:12) at .<clinit>(<console>) at .<init>(<console>:7) at .<clinit>(<console>) at $print(<console>) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at scala.tools.nsc.interpreter.IMain$ReadEvalPrint.call(IMain.scala:731) at scala.tools.nsc.interpreter.IMain$Request.loadAndRun(IMain.scala:980) at scala.tools.nsc.interpreter.IMain.loadAndRunReq$1(IMain.scala:570) at scala.tools.nsc.interpreter.IMain.interpret(IMain.scala:601) at scala.tools.nsc.interpreter.IMain.interpret(IMain.scala:565) at scala.tools.nsc.interpreter.ILoop.reallyInterpret$1(ILoop.scala:745) at scala.tools.nsc.interpreter.ILoop.interpretStartingWith(ILoop.scala:790) at scala.tools.nsc.interpreter.ILoop.command(ILoop.scala:702) at scala.tools.nsc.interpreter.ILoop.processLine$1(ILoop.scala:566) at scala.tools.nsc.interpreter.ILoop.innerLoop$1(ILoop.scala:573) at scala.tools.nsc.interpreter.ILoop.loop(ILoop.scala:576) at scala.tools.nsc.interpreter.ILoop$$anonfun$process$1.apply$mcZ$sp(ILoop.scala:867) at scala.tools.nsc.interpreter.ILoop$$anonfun$process$1.apply(ILoop.scala:822) at scala.tools.nsc.interpreter.ILoop$$anonfun$process$1.apply(ILoop.scala:822) at scala.tools.nsc.util.ScalaClassLoader$.savingContextLoader(ScalaClassLoader.scala:135) at scala.tools.nsc.interpreter.ILoop.process(ILoop.scala:822) at scala.tools.nsc.interpreter.ILoop.main(ILoop.scala:889) at xsbt.ConsoleInterface.run(ConsoleInterface.scala:57) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at sbt.compiler.AnalyzingCompiler.call(AnalyzingCompiler.scala:73) at sbt.compiler.AnalyzingCompiler.console(AnalyzingCompiler.scala:64) at sbt.Console.console0$1(Console.scala:23) at sbt.Console$$anonfun$apply$2$$anonfun$apply$1.apply$mcV$sp(Console.scala:24) at sbt.TrapExit$.executeMain$1(TrapExit.scala:33) at sbt.TrapExit$$anon$1.run(TrapExit.scala:42)

Need to republish for 2.10. Thanks for reporting!

I am also facing the same problem... here is my exception
