AWS SDK for Go V1 has reached end-of-support. We recommend that you migrate to [AWS SDK for Go V2](https://docs.aws.amazon.com/sdk-for-go/v2/developer-guide/). For additional details and information on how to migrate, please refer to this [announcement](https://aws.amazon.com/blogs//developer/announcing-end-of-support-for-aws-sdk-for-go-v1-on-july-31-2025/).

# Building an AWS CodeBuild Project
<a name="cb-example-build-project"></a>

The following example builds the AWS CodeBuild project specified on the command line. If no command-line argument is supplied, it emits an error and quits.

```
package main

import (
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/codebuild"
    "fmt"
    "os"
)

// Builds a CodeBuild project in the region configured in the shared config
func main() {
    // Requires one argument, the name of the project.
    if len(os.Args) != 2 {
        fmt.Println("Project name required!")
        os.Exit(1)
    }

    project := os.Args[1]

    // Initialize a session in us-west-2 that the SDK will use to load
    // credentials from the shared credentials file ~/.aws/credentials.
    sess, err := session.NewSession(&aws.Config{
        Region: aws.String("us-west-2")},
    )

    // Create CodeBuild service client
    svc := codebuild.New(sess)

    // Build the project
    _, err = svc.StartBuild(&codebuild.StartBuildInput{ProjectName: aws.String(project)})
    if err != nil {
        fmt.Println("Got error building project: ", err)
        os.Exit(1)
    }

    fmt.Printf("Started build for project %q\n", project)
}
```
