Subject [jira] [Commented] (IVY-1284) Ivy XML files fail with "Content is not allowed in prolog" when using Polipo proxy cache
Date Mon, 09 May 2011 21:48:03 GMT

    [ https://issues.apache.org/jira/browse/IVY-1284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13030916#comment-13030916
] 

Maarten Coene commented on IVY-1284:
------------------------------------

Since you are using maven repositories, Ivy will look for a POM file instead of an IVY file.
I guess it goes wrong there, could you take a look in your ivy-cache and open the "commons-collections-3.1.xml.original"
file to see it is a valid maven POM file?

> This is an interesting issue, and one that I'm not 100% is a result of the proxy cache,
but:
> 1. Set up Polipo (http://www.pps.jussieu.fr/~jch/software/polipo/) out of the box using
Macports (sudo port install polipo)
> 2. Set up the System Preferences to use the HTTP proxy to go through Polipo.
> 3. Delete the ~/.ivy2 directory
> 4. Go to the SBT project you have set up, and type "sbt update" (or I'm assuming any
Ivy related network task)
> Instead of getting the file you expect, you get the following:
> Getting org.scala-tools.sbt sbt_2.7.7 0.7.4 ...
> [Fatal Error] ivy-0.1.31.xml.original:2:1: Content is not allowed in prolog.

> Inspecting the ivy.xml file in question showed binary gibberish.  Situation resolved
itself when I turned off the proxy through System Preferences, deleted the .ivy2 directory,
and then ran "sbt update" again.
