Connect File Pulse plugin is not loading

I am trying to install filepilse-2.4.1 but not getting the plugin loaded. I am using a Centos which is a unix OS. Also if it matters I am using a vanilla Kafka. Not a Confluent Platform and Not a Docker.

What I have done:

1. I have downloaded the zip file from github for version 2.4.1.
2. Unzipped the filepuse-2.4.1. and added the path to my connect.properties file like so: plugin.path=/opt/filepulse-path
3. Restarted my Kafka connect.
4. Checked to see if the Connect File Pulse plugin is correctly loaded: $ curl -sX GET http://localhost:8083/connector-plugins | grep FilePulseSourceConnector

Result: Nothing is showing up. I also tried to run this: $ curl -sX GET http://localhost:8083/connector-plugins and I am able to see some of the other connectors.

Am I missing something or doing something wrong? I would appreciate any input/suggestions.

Thank you!

Just an update: after updating the Java version to 11 I am able to see the FilePulse plugin now. Thank you all for the help.

1. Please create dedicated directory for plugins (ie /usr/share/confluent-hub-components)
2. create new subdirectory streamthoughts-kafka-connect-file-pulse
3. unzip connector to the above directory
4. Modify kafka-connect settings to include path to plugins to include parent path

plugin.path=/usr/share/java,/usr/share/confluent-hub-components

[root@264be6190212 streamthoughts-kafka-connect-file-pulse]# pwd
/usr/share/confluent-hub-components/streamthoughts-kafka-connect-file-pulse
[root@264be6190212 streamthoughts-kafka-connect-file-pulse]# ls
assets  doc  etc  lib  manifest.json

Then start Connect and check logs - You should be able to see something like
