Jenkins build setup for Go Projects

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..

Answer 1

In addition to letting the Go plugin handle your GOROOT, there are some nuances to the GOPATH as well when it comes to getting dependencies. We are putting our *.go source files in the root of our Git repositories, so they are easily managed via go commands on the Dev desktops. So, I am using a build script to trick Go into thinking there is a package called main under /src/main via a symlink so that I can use the same script to build all of my go packages and pull the dependencies. Here is my build script:

#!/usr/bin/bash export GOPATH=$WORKSPACE mkdir -p $GOPATH/src ln -f -s $WORKSPACE $GOPATH/src/main go get main CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main main

I use jenkin too but write build.sh by myself. To give you a reference:

build.sh

#!/usr/bin/bash

WORKROOT=$(pwd)
cd ${WORKROOT}

# unzip go environment
go_env="go1.6.2.linux-amd64.tar.gz"
wget -c http://path/to/go/go1.6.2.linux-amd64.tar.gz
tar -zxf $go_env
if [ $? -ne 0 ];
then
    echo "fail in extract go"
    exit 1
fi
echo "OK for extract go"
rm -rf $go_env

# prepare PATH, GOROOT and GOPATH
export PATH=$(pwd)/go/bin:$PATH
export GOROOT=$(pwd)/go
export GOPATH=$(pwd)

# build
cd path/to/your/project
go build
if [ $? -ne 0 ];
then
    echo "fail to go build"
    exit 1
fi
echo "OK for go build"

because jenkins works very well with maven. you can build golang projects under jenkins with mvn-golang plugin and also make reports compatible with jenkins
