When this option is checked, no new builds of this project will be executed.

This can be helpful when you want to temporarily prevent a project from being built. For example, if your project depends on some infrastructure — e.g. a test server, or a source code repository — and you know it will be unavailable for a period of time, you could disable the project to prevent unnecessary build failures (and any corresponding notifications) during this period.

You can also disable (or re-enable) this project by clicking the Disable Project (or Enable Project) button on this project's main page.
