Found some Open Source for interacting with Twitter using Twitter API, but could not find the jar file needed by the import statements:
They appear to be from Knime, but they are nowhere to be found with Google search.
Thanks in advance.
More info. It should be a plug-in called org.knime.twitter.api [3.0.0,4.0.0]. Not sure what the repository URL is to add the plug-in to my Knime SDK. Thanks!
It is solved. The plugin is in KNIME Analytics Platform. The page, https://www.knime.com/downloads/update shows how to install the plugin. There are two options, URL and file. The former option does not work but the file option works for me.
