Question

Is there a way when designating a resolver ivy pattern to be able to produce the following output?

C:/MyRepository/MyCompany/MyModule/1.2.3/4/ivy.xml

Currently, the [revision] token resolves to the full 4-digit version number. I’d like to be able to use the first three digits of the revision for a part of the pattern and use the last digit for a subfolder below that. Is this possible or would I have to write custom ant code to do this?

Something like this:

<resolvers>
    <filesystem name="myresolver">
        <ivy pattern="${my.dir}/[organisation]/[module]/[shortversion]/[rev]/ivy.xml" />
        <artifact pattern="${my.dir}/[organisation]/[module]/[shortversion]/[rev]/([target])[artifact].[ext]" />
    </filesystem>
</resolvers>

where:

${my.dir} = C:/MyRepository/

and the ivy tokens have these values:

[organisation] = MyCompany
[module] = MyModule
[shortversion] = 1.2.3
[rev] = 4

I realize I’m making up these fictitious tokens (shortrevision and rev), but what I’d like to be able to do is get at the revision number parts (major, minor, build, revision) so that I can use them in the pattern.

ivy supports extra attributes which can attached to the dependency declaration as follows:

<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">
    ..
    <dependency org="MyCompany" name="MyCompany" rev="1.2.3" e:buildnum="4"/>

The extra attributes are used as normal within your resolver patterns as follows:

<resolvers>
    <filesystem name="myresolver">
        <ivy pattern="${my.dir}/[organisation]/[module]/[revision]/[buildnum]/ivy.xml" />
        <artifact pattern="${my.dir}/[organisation]/[module]/[revision]/[buildnum]/[artifact].[ext]" />
    </filesystem>
</resolvers>
