Yes, the API often changes as versions change.

At a glance, there's nothing that jumps out as being wrong in your script, but I really can't bothered to read it properly without you saying which line might be a problem. I don't see any reason to put in any effort when the computer will tell us where it is faster.

Could you use the built-in script editor?  That will tell you where things are wrong in your script.

Yes, I use the built-in script editor. My scripts had no errors in my old version. My Jira is upgraded to 7.4.4. and all scripts gives static type checking errors. How can I fix all these errors? Is there any easy way to fix all of them at one-step correction?

No, you need to understand them to fix them.  A computer can't guess at what you were intending to do in your script.

However, static type checking is something that needs to be done when you use a weakly typed language like Groovy.  I personally dislike weakly typed languages because of this sort of woolly thinking they encourage, and I tend to fix most of the ones I cause by swapping to properly declared objects.  (instead of "def thing = ", I'll say "int thing = ", so I can rely on knowing what type of object "thing" is later)

There's a less opinionated write up about static object types over at which includes a lot of information on fixing them.
