Can't build RapidMiner 7.5 from source

Hi, I'm having trouble building RapidMiner Studio since I downloaded the latest source from github. Even with no local changes I get dependency issues and NoClassDefFound errors everywhere when I run tests. Do I need to update something else?

    Hi, please try this thread on Github:https://github.com/rapidminer/rapidminer-studio/issues/1

    Thank you for the reply, Zoltan. I was able to avoid the NoClassDefFound issues that way, but I still have dependency problems with the org.h2.api and org.h2.tools libraries. I don't see these in the dependency sections of the build.gradle file. Do I need to add them, and if so, which version should I use?

    They are included ascompile 'com.h2database:h2:1.4.194'so this might be an issue with your Gradle setup then.

    Thanks, I was able to locate those. What about the com.vlsolutions.swing packages? I am now at a loss for where to find those, if they are in one of the included dependencies.

    Just search for "vldocking" in build.gradle:https://github.com/rapidminer/rapidminer-studio/blob/master/build.gradle

    Thank you Zoltan for your patient responses. I am now able to build RapidMiner but when I try to run RapidMinerGUI.java from inside IntelliJ, I get the following error:

    Exception in thread "main" java.lang.ExceptionInInitializerError

    What properties file is this referring to?

    I downloaded the latest 7.5.1 code and received the same error, but was able to work around it by manually copying gradle.properties to my build directory. I can now run RM, albeit a bunch of exceptions in the console.

    I think I'm good for now, but wonder if others are experiencing similar difficulties. I just downloaded the code from github and ran as-is, no local changes.
