Where is Math Formula in SDK KNIME v3.4.1. ?

Dear KNIME team,

I'm having problems installing the extension

KNIME Math Expression (JEP)    3.4.0.v201704201014

in KNIME v3.4.1. that I open through the Eclipse SDK.

I tried to install the extension through Eclipse > Help > Install new Software, however, using the update site http://update.knime.org/analytics-platform/3.4/, I only find the sources for Math Expression, but not the actual extension.

Is it possible that the Math Formula node that I'm missing is located in a different extension? For example, the other extension I was missing, KNIME Quick Forms, I found in the KNIME JavaScript Views extension.


The exact steps to reproduce the problem are as follows:

  • Start the SDK and run KNIME through it
  • Load example workflow 50_Applications > 16_MarketBasketAnalysis > 01_Build_Association_Rules_for_MarketBasketAnalysis
  • Warning message pops up reporting that the node Math Formula is missing. 
  • Installer suggests to install the item KNIME Math Expression (JEP) 3.4.0.v201704201014, which I then searched for in Eclipse.


Interestingly, I don't encounter the problem when I run the general KNIME Analytics Platform 3.3.1.

I'd greatly appreciate your help!




You cannot install extensions in KNIME when started from the SDK. Instead you have to add the extensions to the target platform in the SDK.
