# Solution

You can implement the "Test" stage as follows.

```groovy
stage('Test') {
    steps {
        sh 'go test ./... -coverprofile=coverage.txt'
        sh "curl -s https://codecov.io/bash | bash -s -"
    }
}
```

You can implement the "Code Analysis" stage as follows.

```groovy
stage('Code Analysis') {
    steps {
        sh 'curl -sfL https://install.goreleaser.com/github.com/golangci/golangci-lint.sh | bash -s -- -b $GOPATH/bin v1.18.0'
        sh 'golangci-lint run'
    }
}
```

Create the credentials for the GitHub token.

You can implement the "Release" stage as follows.

```groovy
stage('Release') {
    when {
        buildingTag()
    }
    environment {
        GITHUB_TOKEN = credentials('GITHUB_TOKEN')
    }
    steps {
        sh 'curl -sL https://git.io/goreleaser | bash'
    }
}
```

The final `Jenkinsfile` looks similar to the solution below.

```groovy
pipeline {
    agent any
    tools {
        go 'go-1.12'
    }
    environment {
        GO111MODULE = 'on'
    }
    stages {
        stage('Build') {
            steps {
                sh 'go build'
            }
        }
        stage('Test') {
            steps {
                sh 'go test ./... -coverprofile=coverage.txt'
                sh "curl -s https://codecov.io/bash | bash -s -"
            }
        }
        stage('Code Analysis') {
            steps {
                sh 'curl -sfL https://install.goreleaser.com/github.com/golangci/golangci-lint.sh | bash -s -- -b $GOPATH/bin v1.18.0'
                sh 'golangci-lint run'
            }
        }
        stage('Release') {
            when {
                buildingTag()
            }
            environment {
                GITHUB_TOKEN = credentials('GITHUB_TOKEN')
            }
            steps {
                sh 'curl -sL https://git.io/goreleaser | bash'
            }
        }
    }
}
```
