Hmm… Unity should not by any means stop importing a package in the middle of the import process, even if a compile error such as this is encountered. The full contents of the package should still be imported. At least this has never happened to me before.
Are you certain that there is no GetVariable.cs file found in your project by searching within it?
In either case though and for your convenience, I can send you the fixed full package if you want.
If so, please send me an email ([CONTACT FORM LINK]) along with your order ID, and I will send you the fixed package as soon as possible.
