Jan Matèrne commented on IVY-608:
---------------------------------
And with splitting into several classes you could use conditional compilation
like in Ant.
{code:xml}
<project ...>
<selector id="needs.jdk1.5+">
<or>
<filename name="**/Java5EnvLoader*"/>
<!-- maybe more -->
</or>
</selector>
<available property="jdk1.5+" classname="java.net.Proxy"/>
<target name="build" ...>
...
<javac ...>
<selector id="conditional-patterns">
<not>
<selector refid="needs.jdk1.5+" unless="jdk1.5+"/>
</not>
</selector>
</javac>
</target>
</project>
{code}
> Add support for importing environment variables

> Issue Type: New Feature
> Components: Core
> Affects Versions: 2.0.0-alpha-2
> Reporter: Jing Xue
> Priority: Minor
> Attachments: import-env-1.patch

>
> Ant supports importing environment variables into properties via the
> <properties environment="env" /> task. If an ivysettings.xml relies on an
> environment variable, the lack of support for this feature in Ivy makes it
> difficult to reuse the same ivysettings.xml in a non-Ant environment, such as
> in IvyDE. I'm submitting a patch to add the support for JDK 1.5+. This
> implementation will throw an exception when running in lesser JVMs.
