Before Create Property events are run just before Artifactory creates a property for an artifact.
In Projects, select the relevant project or All.
From the Administration module, click Workers.
The Workers screen appears.
Click + New Workers and select New Event Driven Worker.
The Create Workers section appears that lists all the types of workers that you can create. The Artifactory section lists workers with a predefined Artifactory system action.
Click Add on the required type of worker.
Configure the worker in the Before Create Property screen.
