Go, running example from github, "import cycle not allowed" error, where did I go wrong?
An example is here
https://github.com/clbanning/x2j/blob/master/examp...

Answer 1

weird, everything compiles.
you do the following, you copy the getmetrics.go file to a separate folder, of
course, before compiling, you do it once:
go get github.com/clbanning/x2j
there is no such error.
