Can Jenkins run several jobs in the same time

Question

I have Jenkins installed for running test automation running on Java, Maven,JMeter etc. The Builds are not generating deployment files and folders, but only reports for the tests. Can I build several jobs one after another (almost in the same time) to run in parallel? they don't have to be exactly in the same time. I just want to make sure that starting the 2nd build won't stop/damage the 1st (already running) build. Thanks

Answer 1

Yes it's possible.

Go to your job -> configuration and check: Execute concurrent builds if necessary

Doc:

If this option is checked, Jenkins will schedule and execute multiple builds concurrently (provided that you have sufficient executors and incoming build requests.) This is useful on builds and test jobs that take a long time, as each build will only contain a smaller number of changes, and the total turn-around time decreases due to the shorter time a build request spends waiting for the previous build to complete. It is also very useful with parameterized builds, whose individual executions are independent from each other.

For other kinds of jobs, allowing concurrent executions of multiple builds may be problematic, for example if it assumes a monopoly on a certain resource, like database, or for jobs where you use Jenkins as a cron replacement.

Answer 2

Go to your job -> configuration and check the Boolean: Do not allow concurrent builds
