I've been using Ivy a bit but I seem to still have a lot to learn.
I have two projects. One is a web app and the other is a library upon which the web app depends. The set up is that the library project is compiled to a jar
file and published using Ivy to a directory within the project. In the web app build
file, I have an ant target that calls the Ivy resolve ant task.
What I'd like to do is have the web app using the dynamic resolve mode during development (on developer's local machines) and default resolve mode for test and production builds. Previously I was appending a time stamp to the library archive
file so that Ivy would notice changes in
file when the web app tried to resolve its dependency on it. Within Eclipse this is cumbersome because, in the web app, the project had to be refreshed and the build path tweaked every time a new library jar was published. Publishing a similarly named jar
file every time would, I figure, only require developers to refresh the project.
The problem is that the web app is unable to retrieve the dynamic jar
file.
The output I get looks something like this:
resolve:

The web app resolve target looks like this:
<target name="resolve" depends="load-ivy">
<ivy:configure file="${ivy.dir}/ivysettings.xml" />
<ivy:resolve
file="${ivy.dir}/ivy.xml"
resolveMode="${ivy.resolve.mode}"/>
<ivy:retrieve pattern="${lib.dir}/[artifact]-[revision].[ext]" type="jar" sync="true" />
</target>
In this case, ivy.resolve.mode has a value of 'dynamic' (without quotes).
The web app's Ivy
file is simple. It looks like this:
<ivy-module version="2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd">
<info organisation="com.webapp" module="webapp"/>
<dependencies>
<dependency name="library" rev="${ivy.revision.default}" revConstraint="${ivy.revision.dynamic}" />
</dependencies>
</ivy-module>
During development, ivy.revision.dynamic has a value of 'latest.integration'. While, during production or test, 'ivy.revision.default' has a value of '1.0'.
Any ideas? Please let me know if there's any more information I need to supply.
Thanks!
