Copy of Your Next Successful Build

What's your build tool?

Metadata

Script

Lack of abstraction

Reinvent the wheel

No reuse

No standard

“Everybody’s responsibility” means “Nobody’s responsibility”

Ideal Build Tool

Parallel task execution

Ant tasks & projects executions

for migration usage

Understands IDEA’s projects

and Eclipse workspaces

Based on Rake

Uses Ruby Gems

Rake syntax

Last version 1.2.3

(Dec 2007; last commit Dec 2007)

Lacks documentation

Based on Rake (Ruby)

Tasks for Java

Maven2: project structure, artifact specs, repos

Easy calls to Ant tasks

Groovy instead of Ruby

No delivery date

XML with attributes, Groovy

NO Plexus! (XBean)

New artifact resolution system

Maven2

Scripting still in plugins!

Admits some problems of Maven2:

code quality & artifact resolution system

“Maven is the AWT of build systems”

@puredanger

Revolution!

"What" instead of "How"

Conflict managers - per configuration

Ant (only more complicated)

Built-in Dependency Managment &

Transitive Dependencies

Convention over Configuration

Verbose XML

Scripting

Standartization and Structure

What is build?

Mainly used with Ant

• all
• latest-time
• latest-revision
• latest-compatible
• strict
• custom

Configuration

Poor Implementation

No separation between

metadata and scripting parts

How your project looks

Java 1.4

Everything is a plugin - Bad Idea! (Eclipse in the past)

Versions auto-update - Not reproducible build: Things “automagically” seize to work

Downloads the Internet on the first run

Project identifier

Where are the sources

Where are the resources

What are our dependencies

Poorly maintained

Never updated

No documentation

Play bad together

Concise Metadata

Corrupted local repository files

Documentation

Garbaged central repository

Limited Dependency Management

Doxia, Plexus & Friends

Dependencies exclusion:

tedious & limited

No conflict management

Procedure

vs.

Copy this to that

Compile with 1.5 target

Filter web.xml

Package war

Powerful!

Control

Tasks variety

Documentation

Good code quality

We want even more!

Revolution!

Project Structure

Build written in Clojure

Standard Project Structure and

Convention over Configuration

1. Declare modules in settings.gradle

2. Declare common properties in parent

3. Run MavenDependencyExtractor.groovy

4. Write the scripting part in Groovy, use Ant tasks

5. Optional - generate pom.xml for IDE integration

6. Run Gradle

7. ?

8. Profit!

It is here just for polyglothism
