Installing KNIME developper without connexion


I’m trying to install knime developper version in a machine that is not connected to the web. I’ve downloaded the knime 32bit linux version here:

And then I’ve downloaded the kn ime update site as zip archive here:

I’ve extracted both archives in the root directory ((…)/eclipse_knime_2.1.0/), but when I launch eclipse and open the knime perspective, none of the extension node appears in the node repository.

What I’m I doing wrong/ missing?

Thanks in advance!

Hi Vincent, you need to create a new runtime configuration in order to run KNIME from within your Eclipse/KNIME SDK environment, see (see last paragraph).
Cheers, Thomas

I think you misunderstood my question :slight_smile: I can run KNIME within KNIME SDK environment, there is no problem about that.

The problem is: I’ve installed manually all extension nodes using the zip archive downloaded at:

When I launch eclipse, and switch to the KNIME perspective, no problem, I canc reate workflow … except that the extension nodes (R, CDK, WEKA …) do not appear in the node repository…

There is no procedure on how to install extension nodes using the zip archive , so I assumed unzipping them in the KNIME directory would do the job as both archive contains plugins/ directory.

Hi Vincent,
Ah, I got it! Sorry. You need to use the UpdateSite and link to the archive you have just downloaded. Just unzipping it into the KNIME directory is not the way an update is performed.
Best, Thomas

So if I have no connexion, I can’t load any of the extension node? Why is that so? Isn’t it the same procedure as creating a new node?

Eg. I create a new node, I export it as jar file, and I put it into the plugin directory, and it should appear… I haven’t tested this procedure yet, but this is what is described in the developper documentation, last section:

Once, the plugin is exported it can be installed in any KNIME installation or any Eclipse installation that contains the basic KNIME plugins by copying the content of the “plugin” folder to the plugin folder of the KNIME / Eclipse installation.

So if this is valid with new node extension, why not with existing extensions?

Hi Vincent, I think that page of documentation is not yet updated. You can still add plugins in a similar way, by copying them to the dropins folder instead of the plugins.
As an alternative you can simply add the downloaded update site (as a zip file) to the update sites as an archive, and use that as an update site (I am not sure whether it will check for other features not present in the update site or not).

I believe, I wrote this in other thread, but it seems to cause lots of confusion, so I do it again: With Eclipse 3.4 the mechanism how features/plugins are managed has drastically changed. The magic keyword is “p2”, which - in my opinion - currentl causes more trouble than it helps (but that’s another story). One of the major implication for users is, that they cannot install new features (i.e. nodes) by just copying the plugins and/or features into the corresponding directories of the Eclipse/KNIME installation. Instead, they must be installed via the Update Manager (or a command line application). One workaround for plugins for which there exists no feature is the dropins folder that Eclipse scans upon each startup. But please use this only if anything else fails. The recommended way is using the Update Manager with the KNIME Update Site or the zipped version of it.


OK, so without connexion, I have to use the zip version as update site or put all oplugins in the dropins, and I’m guessing it’s the same procedure to add a new node (?)…

I think it would be usefull if this was mentioned in the official documentation.

Similarily, it would be usefull to have several complete step by step tutorials with different levels of complexity on how to create a new custom node with the developper version (eg. first a simple 1:1 node, then a n:m node with custom port type etc…).

KNIME seems to be a powerfull environment, and one of its potential strength is its scallability as a free, modular and open source tool.

In my opinion, currently the only thing really missing is a full documentation, particularilly for the developpers version, with several practical, documented examples, and a full background introduction on how knime works behind the scene.

Anyway, thank you both for your answers :slight_smile:

Any chance of getting a zipped version release of the KNIME Labs content once in a while? Otherwise I won’t be able to use text or image processing, which is really a shame… ;-/


NM, I found it now. :slight_smile:


I have the same problem. I have KNIME for win 32. I have downloaded the zip file "Download KNIME Update Site (840MB)". I extracted this file in dropins folders but no extesion added to my KNIME software. What sould I do next to see the additional nodes?

We don't recommend using the dropins folder for KNIME extension. The better way is to use the in-built Eclipse/KNIME update mechanism to install extensions. If you don't have access due to proxy / firewall restrictions, you can use this zipped update site and register in the update dialog.

I know I should use that way but i want to install extensions with this zip file.

How can I use this zip file?? I extracted it in dropins folder but nothing happend.

I use KNIME for windows. I don't use Eclipse/KNIME. when i use Eclipse/KNIME the only thing I see is the Eclipse IDE. How can I run the KNIME mode and see the nodes of KNIME for doing a Data Mining project in Eclipse/KNIME?

I can not find a tutorial for KNIME!

To confirm, you are indeed running the latest knime from our website, right?


If so, I think you will find what you are looking for in the Knime help menu.  Click on Install New Software then on the 'add' button at the top of the installation dialog. Finally, use the "Archive" button to point Knime at your zip file .  From there you should be able to select your local update site and proceed without further complications.  If not, let me know.

Also, I performed a minor update to our documentation on this topic so that it may be easier to find in the future.

and a link to the getting started guide...

thanks. it works well.
