[jira] [Commented] (IVY-1475) ivy:cachefileset fails with String index out of range on Windows

["Patrice Matignon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IVY-1475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14016101#comment-14016101 ] 

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 />

> 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)
> 	at org.apache.ivy.ant.IvyTask.execute(IvyTask.java:271)
