Introduction

The purpose of this groovy script is to "kick-start" a Java project's use of the ivy plugin for ANT.

Usage

$ groovy ant2ivy --help
usage: ant2ivy
 -a,--artifactid <arg>   Module artifactid
 -g,--groupid <arg>      Module groupid
 -h,--help               Show usage information
 -r,--mavenUrl <arg>     Alternative Maven repository URL
 -s,--sourcedir <arg>    Source directory containing jars
 -t,--targetdir <arg>    Target directory where write ivy build files

Example

The following example scans tomcat's libraries and generates the ivy files to download them from Maven Central

$ groovy ant2ivy -g com.example -a demo -s /opt/apache-tomcat-7.0.21/lib -t build
13 [main] INFO Ant2Ivy - Searching: http://repository.sonatype.org ...
3910 [main] WARN Ant2Ivy - Not Found: ecj-3.7.jar
8025 [main] INFO Ant2Ivy - Generating ant file: /home/mark/build/build.xml ...
8036 [main] INFO Ant2Ivy - Generating ivy file: /home/mark/build/ivy.xml ...
8051 [main] INFO Ant2Ivy - Generating ivy settings file: /home/mark/build/ivysettings.xml ...
     [copy] Copying 1 file to /home/mark/build/jars

Jar files which cannot be identified are placed into a local directory which ivy is configured to pull from.

Generates the following files

build.xml

<project name='Sample ivy build' default='resolve' xmlns:ivy='antlib:org.apache.ivy.ant'>
  <target name='install' description='Install ivy'>
    <mkdir dir='${user.home}/.ant/lib' />
