In Bamboo how can you access\edit plan and global variables in windows powershell script

[Ryan Vice]

I'd like to be able to read and update plan and global variables from PowerShell scripts. Ive seen that you should be able to take a variable like

bamboo.buildNumber

and access it in script by using

$bamboo_buildNumber

and i've also seen that you need to do

$BAMBOO_BUILDNUMBER

but neither is working for me.

What's the correct way to access these varialbes? And can you set them and then have that value available to other tasks, stages, deployment projects, ect...

If you run it as a Script command or pass in as arguments you can use Bamboo Variables in PowerShell. No matter where you use bamboo variables the format is the same

${bamboo.buildNumber}

If you continue to have problems, make sure to check the log as it shows which variables it's substituting before calling anything:

command	29-Jan-2014 09:24:36	Substituting variable: ${bamboo.buildKey} with TOOLS-TINK-BUILD
command	29-Jan-2014 09:24:36	Substituting variable: ${bamboo.buildNumber} with 2
command	29-Jan-2014 09:24:36	Substituting variable: ${bamboo.buildTimeStamp} with 2014-01-29T09:24:21.118-05:00
command	29-Jan-2014 09:24:36	Substituting variable: ${bamboo.repository.revision.number} with 187290
command	29-Jan-2014 09:24:36	Substituting variable: ${bamboo.repository.branch.name} with Trunk

As for editing, there is a plugin that can inject variables from a text file which you could create with PowerShell; personally, I've got inconsistent results with it so I abandoned it but here it is: https://marketplace.atlassian.com/plugins/com.atlassian.bamboo.plugins.bamboo-variable-inject-plugin. I'm not sure if the API will allow changes to any Global Variables or if it does whether the changes would be available in the same build in a later step (might cache).
