The previous version of dottylab failed on Linux due to an improper classpath building.

The current one seems to work correctly,

without the uberJar but with

clean

package

that build a small .jar file

Aha. Thanx. Will try.

[bjornregnell]

Which Java version are you building with? Still fails with same error using OpenJDK 8.

The build reports no errors with sdk install java 17.0.1-oracle. But nothing happens when:

$ java -jar target/scala-2.13/ScalaLab.jar

[sterglee]

ScalaLab needs to access the lib folders therefore it should be run from the project's root folder.

Therefore, you should copy the ScalaLab.jar to the project's root folder, and run the command java -jar ScalaLab.jar or better ./Linux64RunScalaLabServerJVM.sh

[bjornregnell]

Aha! Yes now it works with createUberJar and copied to the root and running with ./Linux64RunScalaLabServerJVM.sh I think it would be good to add this info to the README.md and also perhaps publish the jar her on github as a release.
