How to Set Up Knime Target Platform?

KNIME Development
#1

I’m completely new to Eclipse and Knime and I’m trying to follow the instructions for setting up an Eclipse target platform for Knime. I’ve done all the downloads I can find and haven’t had any luck. I’m getting an error message indicating that some dependencies cannot be resolved. See screen shot:

The versions I’m using are as follows:
JDK 9.0.4
Ecliipse Oxygen 3.7
Knime 3.5.2

Any help or clue as to what I should try next would be appreciated.

Hi @mdenzien,
You can edit the target definition and remove the KNIME Build System, you don’t need it when developing KNIME nodes. To do this just double-click on the update site and scroll down to the KNIME Node Development Tools group, make sure all check-boxes, but the KNIME Testing Framework one, are unchecked.

Also did you have a look at our SDK Setup Guide yet?
best,
Gabriel

Many thanks Gabriel. The SDK Setup Guide looks like it’s just the thing. I’ll check it out and I may have a follow up question or two.

The SDK Setup Guide did the trick, and I now have Knime running in debug mode. Thanks again.

One small thing about the setup guide: When I went to install the Eclipse Plug-in Development Environment, the name on the repository was “Eclipse Plugin Development Tools” rather than “Eclipse Plug-in Development Environment”. Though this caused only momentary confusion, might it warrant a correction to the setup guide?

A follow-up question: When I get to creating my own nodes, does it make sense to use the New Node Wizard? If so, how might I install it into Eclipse? (It doesn’t seem to be there at the moment.) Or, is there another simple way other than building up all the classes from scratch?

Cheers

I am glad it is working for you know! Thank you for the note regarding the PDE / PDT, I will correct it ASAP.

Creating your own nodes

  • The sdk setup repository contains an example node, you can just copy that project and start developing.

https://github.com/knime/knime-sdk-setup/tree/master/org.knime.example.node

  • Alternatively, especially if you like to use maven you can try out:
  • You could also install the New Node Wizzard via the KNIME update site (the same used in the target platform definition).
