Go / Revel:使用/导入修改版的外部包?

Here is a thing I don't understand.

I "go get" a go package on github. Then, I wanted to modify it. So, I forked it and change the name.

Then, "go get" once more, with my new repo name.

I changed my import lines and then : "revel run". My app was working. And since I removed all the older package files, I was sure my app was running my fork.

But, if I just add this line : fmt.Println("executing: ", sqlStatement) the console / term will never show my sqlStatement or even the word "executing".

However it does show the others "fmt.Println" that was already here in the original package.

What did I do wrong?
