ATG Ant Plugin

atg-ant-plugin is a set of build tools for making the compilation of ATG Dynamo projects much easier. As its name suggests, this is an Apache Ant plugin forked from the original AtgAnt plugin.

Installation

First, download the source code:

git clone https://github.com/jvz/atg-ant-plugin.git

Next, build and install the project to your local Ant lib directory:

ant install

Usage

The following is your ideal build.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<project name="base" default="clean-build" xmlns:atg="antlib:atg.tools.ant">
	<atg:atg home="${user.home}/ATG/ATG11.0"/>

    <target name="clean-build" description="Clean and build directory">
        <subant target="clean-build" genericantfile="atg-module-build.xml">
            <atgRequiredModules
                    atgHome="${atg.home}"
                    modules="proj3,proj1"
                    filters="proj*,base"/>
        </subant>
    </target>
</project>

The taskdef command loads in the new AtgAnt tasks. You should point the classpath attribute of this task at the location of the atgant.jar file.

The atgRequiredModules task provides a list of atg modules referenced by the two modules given, using their META-INF/MANIFEST.MF's ATG-Required entries. The filters make sure we only run the projects with the given names.

The code uses the list of ATG Modules to run another ant script atg-module-build.xml over each of the found modules

The atg-module-build.xml file looks like this

<?xml version="1.0" encoding="UTF-8"?>
<project name="base" default="clean-build">
    <property name="src.dir" value="src"/>
    <property name="build.dir" value="classes"/>

    <target name="-init">
        <available property="src.dir.exists" file="${src.dir}" type="dir"/>
        <atgModuleName atgHome="${atg.home}" property="module.name" module="."/>
        <echo message="ATG Module ${module.name}"/>
    </target>

    <target name="-clean">
        <delete dir="${build.dir}"/>
    </target>

    <target name="-compile-java" if="src.dir.exists">
        <mkdir dir="${build.dir}"/>
        <javac srcdir="${src.dir}"
               destdir="${build.dir}"
               debug="on">
            <classpath>
                <atgClasspath atgHome="${atg.home}" modules="."/>
            </classpath>
        </javac>
    </target>

    <target name="-build" depends="-compile-java"/>

    <target name="clean-build" depends="-init,-clean,-build"
            description="Clean and Build module"/>

</project>

This file will compile a single ATG Module, and the previous file runs this ant script over all of your project's modules

The atgModuleName task is used to get the name of a particular module, in this case the module "." -- this is a special name which means my current build directory. Because this script is run over each module, it will print out the name of the module it's current working on.

The atgClasspath task generates the classpath of the current module. This is the classes listed in the module's META-INF/MANIFEST.MF file ATG-Class-Path entries, plus the ATG-Class-Path of all the modules this module is dependent on.

More details on these commands is given later

This system could be extended to perform other ATG module related tasks, such as running code quality tests or jsp compilation.

AtgClasspath task

Description

Gets the classpath for one or more ATG modules

The classpath is generated by referencing the modules' META-INF/MANIFEST.MF file's ATG-Class-Path entries. If the modules reference other modules using ATG-Required entries, then those modules are added to the classpath. This happens recursively.

The classpath built is in the same order as that will be used by ATG when the module is run.

The command is mainly used to generate the classpath for compiling the java code in a module. It could also be used for the classpath for JUnit tests run against the code in the module.

Parameters

• atgHome
  • The directory into which ATG has been installed.
  • Required.
• modules
  • A list of modules you want to include into the classpath, separated by commas, semi-colons or colons. The module "." means the current ant base directory. You can use simple wildcards such as mod* to indicate all modules starting with "mod", or mod** to mean all modules, including in subdirectories, starting with "mod". For example, module1.base would be matched by mod** but not by mod*.
  • Optional. Default is "."
• filters
  • Archive file to expand.
  • Optional.

AtgModuleName task

Description

Gets the name of the ATG module given to it.

The name of a module is its name as would be recognised by another ATG module: e.g., PublishingAgent.base.

The command is mainly used to get the name of the module which is the current Ant base directory, but it could be used simply to convert directory names from the system format classpath to ATG's dot notation.

Parameters

• atgHome
  • The directory into which ATG has been installed.
  • Required.
• module
  • The module whose name is being sought.
  • Optional. Default is "."
• dir
  • The directory of the module whose name is being sought. You can not specify both dir and module.
  • Optional. Default is the value from module.

AtgRequiredModules task

Description

Gets the list of modules need by (and including) the modules given.

The classpath is generated by referencing the modules' META-INF/MANIFEST.MF file's Required entries. This happens recursively.

The classpath built is in the same order as that will be used by ATG when the module is run, with the base modules appearing first.

The command is mainly used to generate a list of modules that need to be compiled for a particular system. For example, if you provide your top level module or list of modules to make a .ear, then it will list all the modules that need to be compiled.

This list will include your custom modules, and ATG's proprietary modules. You may need to use the filter parameter to restrict the list of modules returned

Parameters

• atgHome
  • The directory into which ATG has been installed.
  • Required.
• modules
  • A list of modules you want to include into the classpath, separated by commas, semi-colons or colons. The module "." means the current ant base directory. You can use simple wildcards such as mod* to indicate all modules starting with "mod", or mod** to mean all modules, including in subdirectories, starting with "mod". For example, module1.base would be matched by mod** but not by mod*.
  • Optional. Default is "."
• filters
  • Archive file to expand.
  • Optional.
