The actual problem is that luxon.js is currently deployed as a fixed and checked in JS file that is part of the sources folder. We need to remove that file and deploy the automatically downloaded artifact right after npm install has been invoked. This is done for all other JS libraries of the data tables distribution but Luxon simply has been forgotten.

Steps to fix the problem:

1. Remove Luxon from https://github.com/jenkinsci/data-tables-api-plugin/tree/master/src/main/webapp/js
2. Reference Luxon latest version in package.json
3. Copy Luxon in the same way to the output JS folder as shown in https://github.com/jenkinsci/data-tables-api-plugin/blob/master/pom.xml#L130
4. Create and deploy the plugin to your Jenkins instance to see if timestamps are still correctly shown in a table that uses Luxon

I would like to work on this issue nicoleschultz 
Currently I am understanding how implementation can be done according to Ulli Hafner's msg.

Thanks a lot for your help - how is it going on? Could you replace the lib?

I am getting issues in deploying the plugin on local instance, can you guide me? 

I am giving github repo yo jenkins to build 

What other essential parts I  should add to successfully build? 

You simply need to build the plugin with mvn verify. Then manually copy the created file as shown in the go.sh script:

cp -fv target/data-tables-api.hpi $JENKINS_HOME/plugins/data-tables-api.jpi

Do you mean to run mvn verify in my IDE terminal or through build job?
Also can you explain me step 3? Do I need to add 

to pom.xml,right?

I have attached console logs of the build
drulli Can you please look at it?

Also can you explain me step 3? Do I need to add

<resource>
 	<directory>${project.basedir}/node_modules/luxon/js</directory>
 	<filtering>false</filtering>
</resource>

Yes. Just try and look if the Luxon files are copied to target/data-tables-api/js/
The folder and JS file needs to mach the file name under the node folder.

You can run the install with mvn verify -Pskip in order to bypass the tests. Maybe the build does not work with JDK 17 correctly yet. (You can try with Java 11, but the tests are not required for your change).
