❗ Unit and Larger Context

Agenda:

  • What is JDK?
  • Maven Build
  • Demo

✒️ -> Scratch Notes

JDK - Java Development Kit
  • Compiler, javac, runtime, java
    • javac compiles source code to binaries for JVM
JRE - Java Runtime Environment
  • Runtime env -> Contains the java launcher
  • Contains JVM and core libs to run java
JVM - Java Virtual Machine
  • VM that execs compiled files
  • This is what makes Java “write once, run anywhere”
Maven
  • Build automation and project management tool for java
    • Others like gradle too
  • Runs on top of JDK
  • Key file: pom.xml
    • Dependency management
    • Provides Project Object Model (POM)
pom.xml
  • Info about
    • Project - coordinates, metadata
    • Config details - build config, dependencies
  • Default vals:
  • Config file for project, ‘blueprint’ that Maven uses to put together project
Maven Build Cycle

Maven is built around the “build lifecycle”

  • default, clean, site
Phases in Default Lifecycle
  • validate - validate the project is correct and all necessary information is available
  • compile - compile the source code of the project
  • test - test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed
  • package - take the compiled code and package it in its distributable format, such as a JAR.
  • verify - run any checks on results of integration tests to ensure quality criteria are met
  • install - install the package into the local repository, for use as a dependency in other projects locally
  • deploy - done in the build environment, copies the final package to the remote repository for sharing with other developers and projects.
