# Packaging the SeaLights Test Listener

The SeaLights Test Listener agent is needed for capturing coverage from the application server. It does this by being defined as a javaagent during run time.

The location of the SeaLights Test Listener jar file that is downloaded by the Gradle plugin is saved in the property `sealights.testListenerPath`\
You can **use this property to copy the jar file into a location that gets packaged** alongside your artifact, for instance in a docker file.

Here is a sample of copying the SeaLights Test Listener into the folder `build`

{% code overflow="wrap" lineNumbers="true" %}

```
task copySealightsTL (dependsOn: test) {
    doLast {
        copy {
            from file(sealights.testListenerPath)
            into "build"
            rename '.*', 'sl-test-listener.jar'
        }
    }
}
```

{% endcode %}
