Hi,

I am using Ubuntu 16.04.4. I get a NoClassDefFoundError when I run java -jar ~/Downloads/rodain-app-2.1.0-beta.7_OtherOS.jar , and double clicking the jar file just does nothing.

java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

here were the java versions that I installed (probably too many):

sudo apt install openjdk-8-jre-headless
sudo apt-get install default-jre
sudo apt-get install default-jdk

I get this error when I run roda-in:

 java -jar ~/Downloads/rodain-app-2.1.0-beta.7_OtherOS.jar

You are missing javafx, can you try installing:

sudo apt install openjfx

That fixed it, thanks! Would that have been installed as expected if I had downloaded from https://www.java.com/en/download/linux_manual.jsp? As such, is there any need to add this to the readme?

I think it is installed by default when using Oracle Java, but it may not be the case when installing OpenJDK.

Thanks @luis100 . I can close this now.
