Why is NoClassDefFoundError thrown with "run" but works fine with "dist"?

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:

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.

NoClassDefFoundError usually occurs if the wrong version of a class is there. For example, an old version of the jts jar file. – Supercolumnar
@ThomasMueller I recompile jts source code. It doesn't help. Still the same error. – Azeotrope
Well maybe the version is too new. H2 uses version 1.13 I think. – Supercolumnar
Could you please rerun with the VM option -XX:+TraceClassLoading (given you are using a Sun/Oracle VM)? – Spry
@ThomasMueller I use the exact same version as H2gis use. – Azeotrope
It looks like you have the following problem: During startup, some values are read from your h2 database. There seems to be a problem during parsing and Java/Scala tries to raise an Exception of type "com.vividsolutions.jts.io.ParseException". But because of some problems with the class loader, the Java VM cannot load the according class. So the root cause is the invalid data is the h2 database. The problem during error reporting follows after that error. Unfortunately the problem with the class loader is not part of the trace excerpt you posted, so I can only speculate on this. – Spry
@Spry Hi, the trace is pretty long. You can view it via link: raw.githubusercontent.com/xchen-tian/weird-error/master/… – Azeotrope

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.

I tried and it didn't work. It seems "org.orbisgis" % "h2gis" % "1.1.0" has nothing inside. I use "org.orbisgis" % "h2-dist" % "1.1.0" instead. – Azeotrope
