Introduction

============

This document is a quick-start guide for the Ant-based Helium build framework. More information can be found from `Helium manual`_.

Installation

=============

<#if !ant?keys?seq_contains("sf")>

Helium can be retrieved from the Hydra_ service:

Configuration

=============

- Helium is configured using a combination of Ant configuration elements (properties, filesets, etc) and other XML files for more complex

  configuration of particular parts of the build. For initial tests run in this quick-start guide you do not need to configure anything, but 

  do please read the following references for more information:

  - `Using Ant <http://ant.apache.org/manual/using.html>`_: specifically the Projects and Properties sections.

  - `Configure Helium  <manual/configuring.html>`_: `common configuration format <manual/configuring.html#common-configuration-format>`_ and `Helium stages <manual/stages.html>`_.

  - `Helium glossary <api/helium/properties-table.html>`_: lists the specific properties used in Helium.

Running builds with Helium

==========================

After configuring the framework, running builds with Helium is simple. The command-line interface is the same as for Apache Ant. 

Please read `Running Ant <http://ant.apache.org/manual/running.html>`_ for more information.

You start the build with ``hlm`` command. Navigate into 'helium' directory (should contain the file ``hlm.bat``) and type::

    hlm [target] [-D<property>=<value>] [-f <ant_build_file>] [-h] [-p -v]

    [target]                        Run Ant target

    [-D<property>=<value>]          Set an Ant property

    [-f <ant_build_file>]           Use another Ant build file

    [-h]                            Print Ant help text

    [-p -v]                         List all Ant targets

    Variable properties for helium:

    -Dsysdef.configuration=default set build configuration, default value is 'default'

    -Dbuild.system=ebs             set build system, default value is 'ebs'

                                      - possible values are 'ebs' and 'ec'

    Usage examples:

    hlm                            build the default build target

    hlm -Dbuild.system=ec-helium   use electric cloud build system

Eg:: 

    hlm -Dbuild.number=1 hi

This is a very simple task found in the file ``\helium\tool\common\common.ant.xml``

The code is shown below::

    <!-- A simple test target that prints a simple message -->  This is a comment line <!--  --> 

                                                                indicates comment text

    <target name="hello">                                       This is the target name 'hello'

        <echo message="Hello!"/>                                what the task does echo the 

                                                                word 'hello'

        <if>                                                    Conditional branch

            <isset property="build.number"/>                    If the property build.number is

                                                                present 

            <then>                                              then 

                <echo message="Ant libs found OK"/>             echo additional text 'Ant libs 

                                                                found OK'

            </then>                                             end of 'then' action

        </if>                                                   end of 'if' action

    </target>                                                   end of target/task

    <target name="hi" depends="hello"/>                         this is the called target which

                                                                depends upon the target 'hello' 

                                                                being run before

                                                                this target is run.
