I'm still an ansible noob here, but wouldn't this NOT install unzip and which if java version is already 1.7 and above?

Yes @ketan, that's correct. @boukeversteegh, can you extract the java installation to a separate task to ensure the other basic dependencies are still installed?

good one, i'm testing out a patch now, will post today or tomorrow

For what it is worth, grep version | awk '{print $3}' is the same as awk '/version/ {print $3}'. However, you don't need to combine awk, sed, and grep for this. You can simplify this to one grep to get the line, and one grep to extract a number from that line.

shell: java -version 2>&1 | grep version | grep -o '[0-9][0-9]*\.[0-9][0-9]*' || echo 0

Alternatively, if you're confident that the first line with a number has the number you want:

shell: java -version 2>&1 | grep -o -m1 '[0-9][0-9]*\.[0-9][0-9]*' || 0.0

okay, cool, thanks for those tips. i'm no longer actively using this playbook, so i can't test it, but if you are confident of course feel free to adapt and merge.
