No progress reported when used inside a gradle build script

[rrajen]

Progressbar works perfectly well when used in a standalone groovy script. However, when that same script is used as part of a gradle build.gradle task then I see no output at all in the console (I tried running my script with and without the "-q" option, and got the same result). My task does what it is supposed to, but surely would be nice to see the ProgressBar showing where it is at. It is a long-running custom task, so having some sort of progress reporting would be great.

I am guessing that this has to do with how Gradle deals with the PrintStream output that ProgressBar is generating.

Thanks.

A recent commit changed System.err to new PrintStream(new FileOutputStream(FileDescriptor.err)). I don't use Gradle myself so I couldn't test, but it might have resolved this issue.
