Subject RE: Ivy can mutate Ant properties? What?
Date Wed, 12 Nov 2008 18:14:08 GMT
The ivy task mutated an Ant property in the Ant script, not in a
settings file.  Is that still expected behavior?  It's true that the
property coincided with a commonly used Ivy property, but I would not
expect Ivy to mutate any Ant property that was not set by Ivy itself.

Yes, this is default behavior.  IVY settings files can have properties
with the option to alter pre-existing properties.  The option is in the
"override" attribute.  If you set it to false, then you will not mutate
any ANT pre-existing properties.

Subject: Ivy can mutate Ant properties? What?

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
