Subject Re: Re: Re: Ivy + hudson CI - problems downloading artifacts, please, help

Hi,

Here is another variant we found:

<caches useOrigin="true" lockstrategy="artifact-lock"/>

Apparently, the default set up is no-lock, therefore in continuous  
integration environment it might cause those issues.

see http://ant.apache.org/ivy/history/2.1.0/settings/lock-strategies.html

Artifact-lock seems to be very good for CI env.

We are going to try it out as it seems to be much less intrusive for our  
environment.

Did you try it?


Thanks,
Eugene
