Hello Java Agent Buildpack

This project shows how to add a custom Java agent to a Cloud Foundry app, using a custom builpack.

Add this buildpack to your manifest:

---
applications:
- name: myapp
  memory: 1G
  random-route: true
  path: target/myapp.jar
  buildpacks:
  - https://github.com/alexandreroman/hello-javaagent-buildpack.git
  - https://github.com/cloudfoundry/java-buildpack.git

This buildpack is actually relying on the official Cloud Foundry Java Buildpack ability to support multiple buildpacks. You need to include this buildpack before the Java Buildpack.

This buildpack defines an extension which is read by the Java Buildpack when the droplet is being built.

A standard supply script will automatically download the Java agent from its repository, and then will generate a file config.yml which will be read by the Java Buildpack to add the Java agent to the command line.

As soon as you start your app, you should see this log entry:
