[jbosstools-issues] [JBoss JIRA] (JBIDE-13346) DirectoryScanner fails on non-existing folders

[Rob Stryker (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-13346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12744614#comment-12744614 ] 

Rob Stryker commented on JBIDE-13346:
-------------------------------------

Is the attached stack trace from an error log entry?  Looking at the codebase, it seems it's a logged warning. It seems it should have no real effect on anything. 

When you try to publish, are you noticing all required resources? Or not? Looking at teh code, a new root folder is created every time on request (not cached), so even with the error being logged, it seems we should just supress the error in this situation if everything else is working ok. 

Can you verify the rest of the behavior is working properly? Just that a warning is logged when it doesn't need to be?

> DirectoryScanner can be made to fail on non-existing folders.
> In our setup, these folders are possibly picked up from the Deployment Assembly settings.
> The folders are created by our custom Builder with highest priority, so appears to work properly with everything else in Eclipse.
> But it seems the Archive DirectoryScanner runs before our builder.
> The stack trace looks like this:
>  
> {code}
> java.lang.IllegalStateException: basedir C:\udvikler\ws\plugins\jb.it.reuters\build\gen-lib-deployable is not a directory
