Dear frieds,

I had a processe of text mining using stop words. I missed the file of stop words that I had but If I remember well is just a txt fil with all words one under the other. Is there any change to version 7.1 community since it does not work.

Best regards,

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.


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:

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

sorry for the late feedback. This will actually be fixed with the next patch release of the web extension.

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 Sad

 Huh can rapidminer do cosine similarity? I have been experimenting  on a 2-instances testing  set with R.  it was alright but I need to do it for a couple of hundred thousands- multiple instances (tweets) against my predefined queries(built dictionary).  Converting them into vector types and calculating the angles.

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");


Same problem is present in RM6.5. Is the error related to a license you mentioned before?

Hi...I usually just add a breakpoint at that place, save that result in the repository, disable the operators that lead up to that point, and add the new example set to the remainder. I do a lot of "versioning" and this happens all the time.

instead of always starting play from the beginning, be able to restart from a given point.  say i added reports on the end now it has to play the full process, with start from here lets you start from a previous spot and finish the process.

--- SOLUTION ---

I was forced in to a workaround. I rewrote a much simpler version of the operator with the Script Operator. A but disappointed not to get any feedback from RapidMiner but nevertheless I completed the task.
