This project supports the article []. It contains the following components, which are described in detail below:

  • AWS: configuration for AWS; sub-directories are named after the AWS service.
  • Deployed-Project: a simple Maven project that will be deployed to S3.
  • Consuming-Project: a simple Maven project that depends on the previous project.
  • settings.xml: example Maven settings to read from a repository server. This is adapted from the Nexus Repository Manager documentation.
  • scripts: some utility scripts to configure projects for those following along at home (these are all Linux bash scripts; if you don't use Linux you're on your own).

Building the sample projects


  • You've configured AWS and Nexus as described in the article. You can find example policy documents and the Lambda source code in the AWS sub-directory, but you'll need to change any references to to your own domain.
  • A JDK (not JRE!). The version shouldn't matter; on Ubuntu I install openjdk-7-jdk.
  • A recent version of Maven. At this time Ubuntu installs 3.0.5, which is rather old; you can download the latest version from

Now for the manual steps to do in this directory:

  1. Remove the .git directory from this working directory. It's not needed (you won't be checking stuff back in), and sometimes Git gets confused when it has nested repositories. Since this is a destructive action, I want you to do it explicitly.
  2. Edit the file settings.xml to change the repository URL, and move it into $HOME/.m2 (after backing-up any existing settings file that you might have!).
  3. Change the distributionManagement section of Deployed-Project/pom.xml to point to your own bucket. Your releases will fail if you leave it pointing at mine.
  4. Run the script scripts/, which moves the directory Deployed-Project to /tmp, turns it into a Git "remote" repository, and clones it back to the project directory. This is necessary for the Maven release plugin to work.

Now you're ready to run mvn release on Deployed_Project. You should see the files being uploaded to S3.

And assuming that your Nexus server is up and running, you should be able to run mvn test in Consuming-Project, and see it download the snapshot from Nexus.
