In this lesson you create your first job.
Use the console to create a freestyle job with one build step.
If you are running Jenkins on MacOS, Linux, or Docker:
Execute shell build step.echo "Hello, Jenkins"
If you select the Execute Windows batch command build step, you will see an error similar to the following:
Building in workspace /var/jenkins_home/workspace/hello
[hello] $ cmd /c call /tmp/jenkins3248756842772121939.bat

Build step 'Execute Windows batch command' marked build as failure
Finished: FAILURE
This is because the program Jenkins uses with the Execute Windows batch command build step is not available on your system.
To fix this error, use the Execute shell build step as described above.
