Hi,
This just appeared on the maven list. I though you may be interested Paul ;)
Specifically look down to the check.properties target. That looks to be what
you want ?

Subject: [idea] Notion of required and optional properties

I don't know if you already have this in Maven but I would find it very
useful. It is the notion of required Ant properties. In all my projects,
I document the required Ant properties (and the optional ones) and I
check in Ant the all required ones are set and valid (verify the file
for file properties) before I let the script go on.
Here is what I use (but I need to improve it to display an error message
per invalid property and not a global one - because it is hard to know
which property failed).
<!--
=============================================================
Display configurable properties values
=============================================================
-->
<target name="display.properties">
<echo message="--- ${project.name.text} ${project.version}
---"/>
<echo message=""/>
<echo message="java.class.path = ${java.class.path}"/>
<echo message=""/>
<echo message="java.home = ${java.home}"/>
<echo message="user.home = ${user.home}"/>
<echo message="ant.home = ${ant.home}"/>
<echo message=""/>
<echo message="j2ee.jar = ${j2ee.jar}"/>
<echo message="log4j.jar = ${log4j.jar}"/>
<echo message="commons.httpclient.jar =
${commons.httpclient.jar}"/>
<echo message="httpunit.jar = ${httpunit.jar}"/>
<echo message=""/>
</target>
<!--
==============================================================
Verify that all mandatory properties have been set
==============================================================
-->
<target name="check.properties" depends="display.properties">
<condition property="properties.ok">
<and>
<available file="${j2ee.jar}"/>
<available file="${log4j.jar}"/>
<available file="${commons.httpclient.jar}"/>
<available file="${httpunit.jar}"/>
</and>
</condition>
<fail message="Missing property or property pointing to an
invalid file (check your build.properties file)"
unless="properties.ok"/>
</target>
<!--
=============================================================
Initialize the build. Must be called by all targets
=============================================================
-->
<target name="init"
depends="check.properties ">
[...]
Wouldn't' it be possible to define an element in the Maven project
descriptor for required and optional properties and have a
maven:check-properties target ?
Note: I have also added this in scarab as an Enhancement (id is MAVE14)
but I find it very hard to use ... especially when it comes to viewing
an issue. It all appears in a small box. There must be another way but
it is not intuitive at all !.
Thanks
