Due to KT-2316 we excluded the jQuery kotlin code from the kotlin-js-library jar; however it seems that it now compiles again so I've just re-included it again.
So whenever the 0.1-SNAPSHOT updates (or if you do a local maven build) it should compile again now. Just make sure you add the kotlin-js-library jar to your maven pom.xml - thats the jar that includes the standard kotlin library and associated JS APIs (like jQuery / HTML5 etc).
Here’s an example of it in use: https://github.com/JetBrains/kotlin/blob/master/libraries/examples/browser-example/pom.xml#L31
