[2.2] Stage or dist gives a java.lang.StringIndexOutOfBoundsException

[J]

Hi,

Since upgrading to play 2.2 when I run stage (or dist) I get the following error

java.lang.StringIndexOutOfBoundsException: String index out of range: -1

Does anyone have any ideas?

Looking at line 236 in the play sbt plugin sources it seems to loop over files ending with 'routes', something special with the stuff in your conf directory?

[J]

Just the routes file and a few other conf files, some of which are symlinked

application.conf
cluster.xml
logconfig.xml
play.plugins
prod.conf
routes
shared.conf -> ../../shared_application.conf
shared_prod.conf -> ../../shared_prod.conf

[Johan Andren]

I can't see an obvious explanation from those files, maybe you could debug and put a breakpoint at PlaySettings.scala:236 and see what the respective strings contain?

[J]

Seems like the symlink files were causing it to fail, removing them allowed it to build.

I think I've found a bug and a bugfix for those softlinks in conf/, see:  https://groups.google.com/d/msg/play-framework/s4NuYJPzjDg/hhvUt-PbL50J
