[SOLVED, some kind of] Build and install binding-jar

Hi There,

I added a feature to the mcp23017-binding and want to test it now on my local raspi/openhabian.

I build the jar from the modified source with maven

mvn clean install

and ive got a org.openhab.binding.mcp23017-2.3.0-SNAPSHOT.jar in the target-folder.
Than I replaced the existing (and working) jar in


and restart the openhab2-service.
After that, I find this message in the log:

2018-07-10 17:02:16.794 [DEBUG] [org.openhab.binding.mcp23017        ] - BundleEvent INSTALLED - org.openhab.binding.mcp23017
2018-07-10 17:02:16.876 [DEBUG] [org.openhab.binding.mcp23017        ] - BundleEvent RESOLVED - org.openhab.binding.mcp23017

2018-07-10 17:02:16.936 [DEBUG] [org.openhab.binding.mcp23017        ] - BundleEvent [unknown:512] - org.openhab.binding.mcp23017

The linked things and items are not working now.

What is wrong with my jar? What do I wrong?

Please help :slight_smile:


You should have placed the changed .jar into the add-ons folder.
Did you have done any changes regarding channels and configuration, you should delete the old things and create new ones with with your new binding.

Which jar should I replace?

 find / -name "org.openhab.binding.mcp23017-2.3.0-SNAPSHOT.jar"


Additional Info: The binding was initially installed via the paper-ui. Is there a better way to install it?

removed all the Things, same error


You should have deinstalled via PaperUI what you have installed via PaperUI.
You could/should check using the Karaf console (command bundle:list) if the binding is reinstalled. If not you can remove it via the console.
A customized .jar should be installed by simply dropping it into the add-ons folder.

Thank you for your answer. I removed all existing mcp23017-binding-Infos by deinstalling via paper-ui and removing the tmp-folders. Checked: Its really gone!

Than installing the customized jar via

cp ...  /srv/openhab2-sys/addons

The Log says:

So, it doesnt help.

As my next step, I’ll comapre my jar against the working, unchanged jar. Or do you have any better idea?

Thank you,

I’ve compared the jars. In my jar, the file


was missing. Ive taked it over, now it works.

Thank you!

Why didn’t you test the changed binding in the IDE in the first place?

The IDE runns on my Laptop. My laptop dont have a I2C-Interface, so I cant use MCP23017-Chips with it.
