Subject Ivy can mutate Ant properties? What?
Date Wed, 12 Nov 2008 17:56:46 GMT
I was surprised today to observe that the ivy:info task can mutate Ant
properties, which are supposedly immutable.  

In this snippet of Ant code, I hardcode some Ant properties.  After a
call to ivy:info, these properties have changed, which should not occur
(as far as I understand).   

Can anyone explain what's going on here?

	<target name="ivy-mutability" depends="ivy-load-commonsettings">
		<property name="ivy.organisation" value="foo.bar"/>
		<property name="ivy.module" value="mutant"/>
		<property name="ivy.revision" value="9.8"/>
		<property name="ivy.status" value="beta"/>
		
        <echo message="pre-info organization: ${ivy.organisation}"/>
        <echo message="pre-info module: ${ivy.module}" />
        <echo message="pre-info revision: ${ivy.revision}" />
        <echo message="pre-info status: ${ivy.status}" />

        <ivy:info settingsRef="module-settings"
                file="${module.output.subdir}/ivy.xml" />

        <echo message="post-info organization: ${ivy.organisation}" />
        <echo message="post-info module: ${ivy.module}" />
        <echo message="post-info revision: ${ivy.revision}" />
        <echo message="post-info status: ${ivy.status}" />
	</target>

This is the output:
test-mutability:
     [echo] pre-info organization: foo.bar
     [echo] pre-info module: mutant
     [echo] pre-info revision: 9.8
     [echo] pre-info status: beta
