Ivy XML files fail with "Content is not allowed in prolog" when using Polipo
proxy cache
----------------------------------------------------------------------------------------
Key: IVY-1284
URL: https://issues.apache.org/jira/browse/IVY-1284
Project: Ivy
Issue Type: Bug
Components: Core
Affects Versions: 2.2.0
Environment: MacOS 10.6.7, sbt 0.7.5, jdk1.6.0_24
Reporter: Will Sargent
Priority: Minor
Fix For: 2.2.0
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.
org.xml.sax.SAXParseException: 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.
