Hello,
I was ready to launch my application for the first time and I got a com/rapidminer/license/AlreadyRegisteredException. Now, since I'm developing on the very same machine I've got RapidMiner installed on, what is he complaining for?!? RapidMiner is initialized like in the FAQ post, btw.
Thank you!

    Hi there,

    I had the same problem building RapidMiner 7.4.0 on Kubuntu Linux.

    • git clone https://github.com/rapidminer/rapidminer-studio.git
    • ... played around ...
    • git reset --hard ; git clean -fxd :/
    • cd .. ; mv rapidminer-studio rapidminer-studio-core ; cd rapidminer-studio-core
    • chmod +x gradlew ; ./gradlew jar
    • java -cp build/libs/rapidminer-studio-core-7.4.0.jar com.rapidminer.RapidMiner
      -> java.lang.NoClassDefFoundError: com/rapidminer/license/AlreadyRegisteredException

    After I manually added the files from

    https://maven.rapidminer.com/content/groups/public/com/rapidminer/license/rapidminer-license-api/3.1.0/rapidminer-license-api-3.1.0.jar

    to the rapidminer-studio-core-7.4.0.jar, the error message changed to

    java.lang.NoClassDefFoundError: com/vlsolutions/swing/docking/ui/DockingUISettings

    Seems like the required files are not included in the Jar package.

    Which version of RapidMiner do you have & which licence?  You might need a developer licence from the sales guys at RM to be able to integrate like that with the latest RM.

    I've got 7.1.00 version. The fact is: how can my company buy RapidMiner without first knowing if it's suitable for its development needs? As a mining tool is state of art and it seemed logical to use it as the engine of mining tools built inside our own software, but it's difficult to take any step without any possibility to try it.

    Hi,

    Can you please post the entire stacktrace? Your code that triggers it would be helpful as well.

    Regards,

    I have the same problem.

    Here is the trace when compiled jar is imported into a new project: 

    Exception in thread "main" java.lang.NoClassDefFoundError: com/rapidminer/license/AlreadyRegisteredException

    Program fails when setting the execution mode: 

        public static void main(String[] args) throws OperatorException, RepositoryException, IOException, XMLException {
            // write your code here

            System.setProperty("RAPIDMINER_HOME", "C:\\dev\\tools\\rapidminer-studio-master");

            RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
            RapidMiner.init();
          ...
    Same problem is present in RM6.5. Is the error related to a license you mentioned before?

    Hi,

    thank you for the feedback! Could you please also post the contents of your build.gradle file? I cannot reproduce the problem on my end so far :(

    Regards,
    Marco

    I have several problems when compiling. The only way that worked for me was to set the version in props.gradle to XXX-SNAPSHOT. Otherwise an error regarding signing a jar was thrown: 

    FAILURE: Build failed with an exception.

    * What went wrong:
    Execution failed for task ':jar'.
    > Cannot create signed jar for rapidminer-studio-master. Missing keystore property.

    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

    BUILD FAILED

    If the version name consisted of "*-SNAPSHOT" the build proceeded and stucked at task generateGitRevFile with an error that a repository was not found. A quick fix consisted of commenting out the offending lines, manually defining the revision number and creating a file tmp/generateGitRev/gitrev. After that the build was successful.

    Next step was was to make a process with the compiled rapidminer jar. The problem like described by Sguish  was the exception described in the previous post.

    Here are some config files:
    build.gradle
    gradle.properties
    props.gradle

    ps: I am missing something or there is no option how to attach a pic or file in the forum?

    Here I am, a bit late. :)

    My stacktrace is very similar to Merto's:

    Exception in thread "main" java.lang.NoClassDefFoundError: com/rapidminer/license/AlreadyRegisteredException

    at rapidminerstuff.RapidMinerStuff.main(RapidMinerStuff.java:21)

    ... 4 more
    C:\PATH\executor-snippets\run.xml:53: Java returned: 1
    BUILD FAILED (total time: 1 second)
    If I comment the RapidMiner init() stuff, of course, it works.

    Hei,
    have maybe anyone of you found a solution for this issue?

    Hi,

    sadly I don't know why this happens. I have forwarded the issue to the appropriate team.
