aws codebuild update-project --name "my-demo-project" \
    --description "This project is updated" \
    --source "{\"type\": \"S3\",\"location\": \"codebuild-us-west-2-123456789012-input-bucket/my-source-2.zip\"}" \
    --artifacts {"\"type\": \"S3\",\"location\": \"codebuild-us-west-2-123456789012-output-bucket-2\""} \
    --environment "{\"type\": \"LINUX_CONTAINER\",\"image\": \"aws/codebuild/standard:1.0\",\"computeType\": \"BUILD_GENERAL1_MEDIUM\"}" \
    --service-role "arn:aws:iam::123456789012:role/service-role/my-codebuild-service-role"

The output displays the updated settings.
