Jenkins为Go Projects构建设置

Question

We are planning to setup Jenkin Build process for Go Projects. I setup Custom Workspace in jenkins and installing go1.6 from "Global Tool Configuration".

I am getting error message while executing go build Below is the GOPATH and GOROOT

GOPATH /var/lib/jenkins/workspace/project/go
GOROOT  /var/lib/jenkins/workspace

---

ain.go:20:2: cannot find package "bytes" in any of:
    /var/lib/jenkins/workspace/src/pkg/bytes (from $GOROOT)
    /var/lib/jenkins/workspace/project/go/src/bytes (from $GOPATH)

What I am missing here?.. Thanks for your help..
