Installing extensions built with 3.6.0 in KNIME 3.5.3

Hi Team,

Schrodinger started building our extensions with 3.6.0. Now, is that possible to install these extensions in KNIME 3.5.3?


The short answer is that “it depends”. Only way to find out is to try installing them and see if they will install and if they then work.

Actually I am getting the below dependency error:

Cannot complete the install because one or more required items could not be found.
Software being installed: Schrödinger Base types Feature (
Missing requirement: Schrödinger types and core files (com.schrodinger.knime.base requires 'bundle org.eclipse.ui [3.109.0,4.0.0)' but it could not be found
Cannot satisfy dependency:
From: Schrödinger Base types Feature (
To: com.schrodinger.knime.base []

I confirmed that in 3.5.3, the version of org.eclipse.ui is 3.108 and in 3.6.0, it is 3.109.
So it is very clear that installing our 18-3 extensions (which are built with 3.6.0) will not work in KNIME 3.5.3.

Am I right?

Correct. However, I don’t think that your extensions needs that very specific version of org.eclipse.ui. You probably forget to set a version range on the dependency and then during build it will be auto-populated with the currently available version as the minimum. Therefore always add version ranges on dependencies!
