Subject email a html file
Date Fri, 28 Jul 2006 23:26:01 GMT

I want to insert a html file in my email, not an attachment. 
Does someone know how to do it in ant.

I've translated your pseudo-code into Ant (see bottom), and I see that it
does seem to remove the need for <antcall>. However, unless *I* have
misunderstood your reply, I think you've misunderstood what I intended the
"build-all" task to mean.

Each server in my case has one preferred transfer type; therefore, it
wouldn't make sense in my case to deploy to the same server via different
mechanisms, at least not consecutively.

Therefore, I think the *deploy-all tasks are spurious, but the rest is on
target, thanks!

Alternatively, it seems Andrew understood where I was going with the
"deploy-all" when he advised the following, so I think I've got the full
solution. :-D

<target name="deploy-all">
   <ant antfile="mydeploymentscript.xml" inheritAll="false">
       <property name="envname" value="stage" />
   </ant>
   <ant antfile="mydeploymentscript.xml" inheritAll="false">
       <property name="envname" value="integ" />
   </ant>

   ... etc
</target>

Here's Dominique's pseudo-code fleshed out, for posterity:
<?xml version="1.0"?>
<project name="cwig" default="deploy">
    <description>Trying it without antcall.</description>
    <property file="$environment}.properties" />
    <taskdef name="svn" classname="org.tigris.subversion.svnant.SvnTask" />
    <taskdef resource="net/sf/antcontrib/antcontrib.properties" />

    <target name="deploy-nfs" if="deploy-type==nfs">
        <echo>I'm doing the NFS deployment</echo>
    </target>

    <target name="deploy-ssh" if="deploy-type==ssh">
        <echo>I'm doing the SSH deployment</echo>
    </target>

    <target name="deploy" depends="-check-deploy, deploy-nfs, deploy-ssh">
        <echo>I'm pretty sure I don't do anything, and that only my
"depends"
        are important.</echo>
    </target>

    <target name="deploy-all" depends="-deploy-all, deploy">
        <echo>I think I, as a task make sense, since i wouldn't want
        to transfer files to the exactly the same destination twice
        (albeit via different mechanisms).</echo>
    </target>

    <target name="-check-deploy">
        <echo>I'm about to figure out which transfer type to use</echo>
        <condition property="deploy-type==nfs">
            <equals arg1="${deploy-type}" arg2="nfs" />
        </condition>

        <condition property="deploy-type==ssh">
            <equals arg1="${deploy-type}" arg2="ssh" />
        </condition>
    </target>

    <target name="-deploy-all">
        <echo>I don't think I make sense, for the same reasons as
"deploy-ant"'s</echo>
        <property name="deploy-type==nfs" value="doesn't matter" />
        <property name="deploy-type==ssh" value="doesn't matter" />
    </target>

</project>

Thanks!,
Jamie
