How can I call an outer process from my own operator?

Hi,

isn't this operator already available with Execute Program?

~Martin

Thanks for you quick reply, Martin!

I know the Execute Program operator provides a similar feature,

but what I'd like to make is one that has similar interface to Execute Python/R.

Hi,

the execution of external applications/ commands is only possible for signed extensions.

If you want to publish your extension on the marketplace, please write me a PM then we can speak about the signing process.

In the meantime or for development purposes you can utilize the open core of RapidMiner Studio. Just add '-SNAPSHOT' to the RapidMiner version (gradle.properties) and the the security restrictions will not be applied.

Next time please post these kind of questions in the development forum.

Cheers,

Marcel

After downloading the template project(rapidminer-extension-template-master) from github, there is only one line in file gradle.properties:

version=1.0.0

As you said, we should add -SNAPSHOT to the version of rapidminer and the the security restrictions will not be applied. 

So what's the key that stands the version of rapidminer in this properties file?

Or I should just add -SNAPSHOT like this:

version=1.0.0-SNAPSHOT

The snapshot classifier should be added to the open-core of RapidMiner (rapidminer-studio/gradle.properties), not the extension template ;-)

I'm afraid, but to my knowledge you would need the source code of RapidMiner Studio for that.

But I read your document named "how to extend RapidMiner", it said I just need use a RapidMiner as dependency like this:

So should I add -SNAPSHOT in this dependency settings? like 7.0.0-SNAPSHOT?

Nope, you should start your extension via the open core of RapidMiner Studio and add the '-SNAPSHOT' tag there (rapidminer-studio/gradle.properties).
