Trigger a long running progress bar

Hello,

I'm trying my hand at plugin development. To start, I'm playing around with yet another Nyan Progress Bar clone (but better!!! :D).

But to test it, obviously, I need some progress bars running, determinate and non determinate, long and short, in modals and in status bar, horizontal and vertical, left to right and right to left, etc.

Are there some ways to manually trigger tasks showing progress bars? I can hit "build project" over and over, I'm sometimes lucky when intellij decides to reindex, but it's not really enough to correctly test.

Thanks in advance.
