# Key CI/CD/Jenkins Concepts and their Usage
## Storing and Fingerprinting Artifacts
1. Create a post-build action for archiving JAR files with the pattern `build/libs/*.jar`. Enable the fingerprinting option.
2. Execute the build. The build should list the artifact `gradle-initializr-1.0.0.jar`.
3. Have a look at the recorded fingerprints of this build.
4. Render the MD5 hash of the artifact and the usage of the artifact.
5. Install the Copy Artifacts plugin.
6. Create a downstream job named `consumer`.
7. Configure the downstream job to use the artifact produced by the upstream job.
8. Run the the build for the job `gradle-initializr`.
9. Have a look at the fingerprints of the downstream job.

<p>
In the job configuration, archive the artifact produced by the build. Check the box for generating fingerprints.
