Before I asked the question I had read the question Play framework java.lang.NoClassDefFoundError only in dev mode and several other posts. They didn't help me to resolve my problem.
I've created a project using Typesafe Activator 1.2.12 and play-scala template. I also employed Slick 2.1.0.
I want to embed h2 database with h2gis extension into play.
When the Play project is started using activator run, the following Execution exception is displayed in the browser:
The following stack trace is on the console:
18013 [play-akka.actor.default-dispatcher-3] ERROR application -

However, if I execute activator dist, and run the application it works well (!)
The jar file for h2 is in lib and in sbt's reference, and without using h2gis, no error occurs.
The source code of the project is on GitHub as weird-error project. Use the project to face the error.
Update:
Here is the trace output with command ./activator run -J-XX:+TraceClassLoading
I only paste a part of it, it seems CoordinateArraySequence raise the exception.

You can fix NoClassDefFoundError error by checking following: Check the exception stack trace to know exactly which class throw the error and which is the class not found by java.
The NoClassDefFoundError is a runtime error in Java that occurs if the Java Virtual Machine (JVM) or a ClassLoader instance attempts to load the definition of a class that could not be found. The class definition exists at compile-time but is not available at runtime.
Try adding those dependencies to your build.sbt file instead of putting jars inside lib.
"com.typesafe.slick" %% "slick" % "2.1.0",
"org.orbisgis" % "h2gis" % "1.1.0",
"com.vividsolutions" % "jts" % "1.13"
in dev mode, play sbt would use multiple classloaders to support hot-reloading whereas after dist there will only be one classloader to handle your project. With that said, putting stuff all at the same place might solve your issue.
