Maarten Coene commented on IVY-1195:
------------------------------------
I think this should be a feature of your buildserver that should not start
building "app" if "lib" is currently being build (or queued for building).
> feature request: retrying resolver wrapper
> ------------------------------------------
>
> Key: IVY-1195
> URL: https://issues.apache.org/jira/browse/IVY-1195
> Project: Ivy
> Issue Type: New Feature
> Components: Core
> Affects Versions: 2.1.0
> Reporter: Stepan Koltsov
>
> I'm requesting a retrying resolver.
> *description*
> Retrying resolver delegates resolution to configured child resolver. If child
> resolver fails, if requests child to perform a resolution again after some
> time.
> *example*
> {code}
> <resolvers>
> <retry name="default" timeout="5m" start="10s" exp="1.5">
> <svn .../>
> </retry>
> </resolvers>
> {code}
> In the example above, "default" resolver will try call SVN resolver to
> resolve dependencies, if SVN resolver fails, it will be called again after
> 10s, then after 15s, then after 27s, and so on, but not after 5 minutes after
> resolver start.
> *motivation*
> We have build server, that builds projects right after commit. Projects
> depend on concrete revisions of another projects, revisions are specified in
> ivy.xml (say, "app" depends on "lib"). Sometimes developers commit to
> dependent project "app" immediately after commit to the base project "lib".
> And in this case there is a high chance, that base project "lib" is not yet
> built (so artifact is not published) at the time of dependent project "app"
> ivy:resolve task run. So build of dependent project "app" fails.
> Retry task could resolve this situation: dependent project "app" build start
> will be delayed until completion of "lib" build.
