jaikiran pai commented on IVY-1562:
-----------------------------------
A test case has now been included for this. I am going to keep this JIRA open
for a while till I sort out an issue in this piece of code when it comes to
dealing with _relative_ paths for the location attribute. Right now, it works
fine when the path is an absolute path.
> Ivy files cannot reference parent module locations of files with a literal
> "%2F" in them

> Key: IVY-1562
> URL: https://issues.apache.org/jira/browse/IVY-1562
> Project: Ivy
> Issue Type: Bug
> Affects Versions: 2.4.0
> Reporter: Mark R
> Assignee: jaikiran pai
>
> The Jenkins [Pipeline Multibranch
> Plugin|https://wiki.jenkins-ci.org/display/JENKINS/Pipeline+Multibranch+Plugin]
> creates a Jenkins workspace directory structure for each branch in a
> repository. If the repository branch name contains a '/' it is encoded as
> '%2F'.
> It seems the extends element under the info element is not handling the
> encoding correctly. Consider the following:
> Workspace:
> /feature%2Ftesting/ivy.xml
> /feature%2Ftesting/folder1/myparentmodule-ivy.xml
> {code:java}
> <ivy-module version="2.0">
> <info organisation="myorg" module="mymodule" revision="1.0.0">
> <extends organisation="myorg" module="myparentmodule"
> revision="1.0.0"
> location="file:/.../feature%2Ftesting/folder1/myparentmodule-ivy.xml"/>
> </info>
> ...
> {code}
> If I hard code the location to be
> file:/.../feature%2Ftesting/folder1/myparentmodule-ivy.xml
> I get this exception (location in build file is calling an ivy retrieve):
> {noformat}
> ...\feature%2Ftesting\my-build-file.xml:427: syntax errors in ivy file:
> java.text.ParseException: Problem occurred while parsing ivy file: Unable to

> This happens because the %2F is translated into a slash (/) which then when
> treated as a file in windows becomes a backslash (\).
> I should be able to get it to work by instead encoding the % by setting
> location=file:/.../feature%252Ftesting/folder1/myparentmodule-ivy.xml.
> However, I get the same exception.
> The reason seems to come from the encoding getting lost at
> XmlModuleDescriptorParser.parseParentModuleOnFilesystem. Running through the
> debugger:
> input:
> {noformat}
> file:/.../feature%252Ftesting/folder1/myparentmodule-ivy.xml
> {noformat}
> results in parser.parseDescriptor getting called with file.toURL =
> {noformat}
> file:/.../feature%2Ftesting/folder1/myparentmodule-ivy.xml
> {noformat}
> Instead of
> {noformat}
> file:/.../feature%252Ftesting/folder1/myparentmodule-ivy.xml
> {noformat}
> Observe that the %252F become %2F. This results in the same exception as
> above. A FileNotFoundException is thrown because the FileURLConnection class
> translates the %2F to be the system slash (\) and so it tries the folder
> 'feature\testing'. Were the %252F not lost it would correctly decode to use
> the literal value of '%2F' and try the folder 'feature%2Ftesting'
> Note trying %25252F does not work as an exception is thrown ("Parent module
> doesn't exist on the filesystem...")
> Here is the code in question:
