Patrice Matignon commented on IVY-1475:
---------------------------------------
To me, the proper way to handle this is to at least report a more explicit
error.
However, I can't think of a way to prevent this situation, so I think this is a
design limitation of the cachefileset task, which should be clear indicated.
Moreover, I'd argue it should be deprecated in favor of <ivy:resources />
> ivy:cachefileset fails with String index out of range on Windows

> Key: IVY-1475
> URL: https://issues.apache.org/jira/browse/IVY-1475
> Project: Ivy
> Issue Type: Bug
> Components: Ant
> Affects Versions: 2.4.0-RC1
> Environment: Windows
> Reporter: Patrice Matignon
>
> On Windows, the ant task <ivy:cachefileset /> can fail with the stack trace
> below, when the resolve includes artifacts located in separate directories in
> separate drives (e.g. c:\ivy2/cache/... ; d:\ivy2\cache ).
> The underlying issue is that cachefileset is an ant fileset and as such it
> requires a base dir.
> Nevertheless, the implementation for this ant task doesn't handle this
> scenario properly: it attempts to find the common base dir for all the
> resolved artifacts, except that every time it runs into a conflicting
> artifacts, it just loses the information and ends up reporting an invalid
> base dir, which causes a fatal StringIndexOutOfBoundsException later in that
> task.
> A sample stacktrace (the actual reported index varies):
> C:\src\trunk\build.xml:839: impossible to build ivy cache fileset:
> java.lang.StringIndexOutOfBoundsException: String index out of range: -24
> at java.lang.String.substring(String.java:1937)
> at java.lang.String.substring(String.java:1904)
> at org.apache.ivy.ant.IvyCacheFileset.getPath(IvyCacheFileset.java:114)
> at org.apache.ivy.ant.IvyCacheFileset.doExecute(IvyCacheFileset.java:82)
