Getting your project started

To get a project off to a good start, consider these items. Even for existing projects, you should address these as you go along or while refurbishing an existing project:

• Team agreement comes first. Make sure everyone is onboard and clear on what build standards are, and understands—at least as an outline—what the build does for them
• Provide a good README.md. This saves you a ton of time in the long run. This is your most important step. A good resource is Yegor's Elegant READMEs
  • Intelligent laziness is a virtue. Time invested in good documentation pays off
  • A good README.md answers visitors questions, so you don't spend time answering trivial questions, and explains/justifies your project to others.
  • Fight Conway's Law with communication!
• Pick a version of Java, and stick to it throughout your local build, CI pipeline, and environment deployments. Do not mix versions.
• Pick Gradle or Maven, and use only one. This project provides both to demonstrate equivalent builds for each. See Use Gradle or Maven for more discussion
• Use build wrappers committed into your project root. These run Gradle or Maven, and coders should always invoke ./gradlew or ./mvnw (use shell aliases if these grow tiresome to type)
  • Build wrappers are shell scripts to run Gradle or Maven. The wrapper takes care of downloading needed tools without getting in the way. New contributors and developers can start right away; they do not need to install more software
  • For Gradle, use ./gradlew (part of Gradle)
  • For Maven, use ./mvnw (a plugin)
• Always run CI on push to a shared repository. It's a sad panda when someone is excited about their commit, and then the commit breaks the other developers
  • In CI, use caches for dependency downloads; this speeds up the feedback cycle from CI (see below)
  • When sensible, move code quality and security checks into local builds before changes hit CI (see below)
• Pick a common code style, and stay consistent. Update tooling to complain on style violations:
  • The team should agree on a common code style, eg, SUN, Google, et al
  • See Choose your code style

Tips

• Consider using client-side Git hooks for pre-push to run a full, clean, local build. This helps ensure "oopsies" from going to CI where they impact everyone. The options are broad. Try web searches on:

  • "gradle install git hooks"
  • "maven install git hooks"

  This article presently has no specific recommendations on choices of plugin or approach for Git hooks.
