AWS CodeBuild Badge update on CodePipeline trigger

Question

I've created an AWS CodeBuild project that includes a build badge and when I trigger the build manually, all works OK (i.e. the badge is updated). I've now added a CodePipeline project that triggers that build based on a GitHub checkin. I can see it go through in the CodeBuild project history but the badge does NOT seem to get updated?

1. Manual build - Build failed - Badge updated
2. Pipeline build - Build succeeded - Badge NOT updated
3. Manual build - Build succeeded - Badge updated

Is this intentional? Am I doing something wrong? Do I have to hack together yet ANOTHER Lambda script to do something so simple!?!?

Answer 1

I've written a build script as a workaround. In the buildspec.yml, I set executable on, then run the script..

  build:
    commands:
      - echo Build started on `date`
      - chmod +x aws_scripts/build.sh
      - aws_scripts/build.sh mvn -B package

The script itself pulls details out of the master pom.xml, sets the badges to "pending", calls the build command, processes the results.

#!/bin/bash

mkdir badges

# Artifact
artifact=$( xmllint --xpath "/*[local-name() = 'project']/*[local-name() = 'artifactId']/text()" pom.xml )

# Version
version=$( xmllint --xpath "/*[local-name() = 'project']/*[local-name() = 'version']/text()" pom.xml )
version=${version/-/--} # Hyphen escaping required by shields.io

# Update badges pre-build
echo "https://img.shields.io/badge/Build-In_progress-orange.svg"
curl -s "https://img.shields.io/badge/Build-In_progress-orange.svg" > badges/build.svg

echo "https://img.shields.io/badge/Version-$version-green.svg"
curl -s "https://img.shields.io/badge/Version-$version-green.svg" > badges/version.svg
