[shrinkwrap-issues] [JBoss JIRA] (SHRINKWRAP-448) Using asSingleFile only works if you return a single file

[Tommy Tynjä (JIRA)]

    [ https://issues.jboss.org/browse/SHRINKWRAP-448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12768458#comment-12768458 ] 

Tommy Tynjä commented on SHRINKWRAP-448:
----------------------------------------

I think asSingleFile has value over asFile()[0]. Think of the method asSingleFile like getSingleResult in JPA. When you are using that method you are expecting one result and one result only. If you would receive multiple results it's an error. It should not just default to the first result, in that case you are better of with asFile()[0] or something like a getFirstFile method.

> You should be able to replace asFile()[0] with asSingleFile, however it doesn't work since multiple files are actually returned.
