Subject RE: Using the same targets across multiple platforms

Ant-contrib and Antelope both have <if> tasks that do what you want.
There have been several message regarding these external projects today
and yesterday.

However, another option would be to create a properties file for each OS
that sets the name of your shell/batch scripts. Then use the built-in
${} property:

  <property file="build-${}.properties"/>

This would simplify your build script I think.

Subject: Using the same targets across multiple platforms

Hi there Guys

I am writing a build script using Ant1.5.2 for a jboss deployment. The
script needs to work across multiple platforms -ie: windows and solaris.
My problem is that in either environment I need to call different jboss
shell scripts -ie: run.bat or

I don't want to have to write different targets for each environment as
it'll make the build script harder to maintain and far to long. I wanted
to use the ant 'if' statement but it appears to only apply to a target,
and what I really want is to be able to apply the if to specific exec
- ie:

<target name="debugjboss" >		
	<!-- Only do if SOLARIS -->
	<exec dir="${bin}" executable="${bin}/">
		<arg line="-c ${projectName}"/>
		<env key="JAVA_OPTS" value="-remote debugging props/>

	<!-- Only do if WINDOWS -->
	<exec dir="${bin}" executable="${bin}/run.bat">
		<arg line="-c ${projectName}"/>
		<env key="JAVA_OPTS" value="-remote debugging props/>

This design essentially needs to be in place for all my targets. Does
anyone know a way of doing what I've described above, or a better way of
doing this? Any help muchly appreciated.
