Unable to launch the Knime Analytics from eclipse

I am unable to launch the Knime analytics from eclipse version Version: 2019-03 (4.11.0). The JDK 8 is installed on the same machine and I have followed the steps given in the https://github.com/knime/knime-sdk-setup
I have set the API-Baseline-Target as Target Platform . Also clicked on checkbox of clear the configuration area before launching. . However, When I am trying to launch the knime analytics platform following error is received:

!SESSION Thu Jun 20 15:36:06 IST 2019 ------------------------------------------
!ENTRY org.eclipse.equinox.launcher 4 0 2019-06-20 15:36:07.074
!MESSAGE Exception launching the Eclipse Platform:

And also before launching the platform the validation error wizard comes listed with jar like com.knime.customization - import package missing

Please help us in resolving the issue.


KNIME is still based off Oxygen, please try using that version of Eclipse as your IDE.

Did you install Eclipse IDE for RCP and RAP Developers ?
I had no problems to launch KNIME from a current Eclipse version (todays download):

Version: 2019-06 (4.12.0)
Build id: 20190614-1200

Futher setup:
MacOS- High Sierra
Java AdoptOpenJDK 1.8.0_212
KNIME-sdk-setup from master branch

Yes I tried that and also now with oxygen as well.
Still it is throwing validation error…

Could you please help in resolving this?

Can I contact you over webex or anyother mode to show you what I did so far…


I’m sorry but I’m afraid I cannot help troubleshooting (don’t know enough about Eclipse). But I am pretty sure someone else will be able. It might help if you provide further information about your environment (like operating system).

No Problem… Problem is resolved just now. I did followed following steps:

  1. Reladed the Knime AP target Platform
  2. Set is as Active Target Platform
  3. Used eclipse oxygen Eclipse for RCP and RAP Developers
    Version: Oxygen.3a Release (4.7.3a)
    Build id: 20180405-1200

Now I am trying to see how can I do the java coding to run the knime workflow.
