Java generator package shortcut does not work

Hello everyone~
I try to use ctrl-alt-c to build constructor but it does’t work. I need to go to package and do it manually. But the ctrl-alt-g works:joy:
It’s Weird. Anyone knows how to fix it. Thanks:)

It would be helpful if you posted a link to the page (click on the Packages tab on this site and search) for the package in question.
