gradle-build

A gradle plugin that combines various tasks and conventions for common builds of Egis.

• Support both Groovy and Java 8
• Automatically updates the JAR/MANIFEST.MF with the GIT SHA1, Commit Date and Build Date

To use this plugin start with the following starter build.gradle file and extend as required:

repositories {
    jcenter()
}

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "gradle.plugin.com.egis:gradle-build:1.7"
        classpath 'org.ajoberstar:grgit:1.1.0'
        classpath "jp.classmethod.aws:gradle-aws-plugin:0.+"
    }
}

ext {
    pkg = 'egis-utils'
    libBucket = '...'
    libPrefix = "libs/"
}

apply plugin: 'java'
apply plugin: 'groovy'
apply plugin: "com.egis.gradle"

jar {
    dependsOn apiJar
    dependsOn srcJar
}

pkg is the name of the package to be build e.g. egis-utils
libBucket is the name of the Amazon S3 bucket to resolve dependencies from
libPrefix is the prefix or folder in the S3 bucket

#Directory Structure#

api/
src/
test/
libs/
  lib.txt
test-libs/
  lib.txt

api/ contents are built into standalone outputs to be imported into other modules - cannot depend on any files within src/
src/ directories contain both Java 8 and Groovy source files
test/ directories contain TestNG classes
lib.txt files contain external dependencies

##Dependency Management

Will search all folders recursively for files named lib.txt and download/resolve dependencies included it from Amazon S3 or Maven

The format of the lib.txt:
{Filename} {MD5} Downloaded from Amazon S3 if the {MD5} does not match
{Filename} Downloaded if the file does not exist
{Filename}.txt Retrieves the contents of the text file and then recursively downloads per each line

To download all dependencies:

gradle setup 

The advantages of using this mechanism:

• Supports any file file format in any folder - i.e. libs/lib.txt and test-libs/lib.txt
• Speed - Downloads directly from Amazon S3
• Server Free
