NEO4J Nodes are not shown


The latest version of KNIME AP (4.2) contains NEO4J nodes which is developed by Redfield AB. Thanks to Redfield for their contribution.

I installed the new version and the extensions. But I can not find the nodes in my KNIME repository. I tried to install KNIME twice from scratch. It is not shown. I also tried to install Neo4J extension from KNIME Hub but I got the message below.

Cannot complete the request. See the error log for details.
“Neo4j extension” will be ignored because it is already installed.

Did anyone has similar problem and any solutions?


Hi again,

After a forum search I found the solution. When you run knime with -clean option all missing nodes appeared in the repository.
