Jaikiran Pai commented on IVY-1623:
-----------------------------------
>From what I can see in the code and its history, I'm not sure why that check
>is there. The "workspaceName" is an internal detail and shouldn't have
>impacted this dependency resolution. I can't seem to find any document which
>states taht the use of "@" is disallowed in versions. I'll try and spend some
>time on the code to understand what it's trying to do, in the coming days and
>see if we can come with a fix without introducing any regressions.
> Are @ symbols reserved in revision strings?
> -------------------------------------------

> Key: IVY-1623
> URL: https://issues.apache.org/jira/browse/IVY-1623
> Project: Ivy
> Issue Type: Question
> Environment: Plain ivy 2.5.0 on the command line, no ant or IDE.
> Reporter: Dave
> Priority: Major
>
> I'm trying to set a dependency with a revision containing multiple @ symbols.
> The naming of these revision strings is outwith my control, so no lectures
> please!
> Here's my simplified ivy.xml:
> {{<?xml version="1.0" encoding="UTF-8"?>}}
> {{<ivy-module version="2.0">}}
> {{ <info organisation="com.asdf" module="thingy" />}}
> {{ <dependencies> }}
> {{ <dependency org="org.blah" name="whatever"
> rev="1.70.0_pkg159@win32@cpp_3_3.3@msvc_141@msvc_141@msvc_15@x86-64" />}}
> {{ </dependencies>}}
> {{</ivy-module>}}
> When I attempt to retrieve the dependencies I get the following:
> {{:::: ERRORS}}
> {{ my-url-resolver: unhandled revision =>
> 1.70.0_pkg159@win32@cpp_3_3.3@msvc_141@msvc_141@msvc_15@x86-64}}
> This appears to be due to code in {{BasicResolver}} that checks for the
> presence of an @, and if it's not followed by the "workspaceName", throws the
> above error.
> So, is @ a reserved character? I don't see any mention this in the ivy
> documentation.
> The "workspaceName" doesn't appear to be referenced within ivy itself, so
> what's it for?
