How to have dynamic variable in bamboo


I'm trying to configure bamboo to have nightly builds. My goal is that after the build, the created artifacts are copied to another folder where all my nightly builds are stored.

The structure I am aiming for is the following:

C:/Sync/.../20140622-Project xx/<all my artifacts>

Everything is in place. I have a variable containing the date, I use the 'Artifact download' task in a Deploy part, and in the path, I put my date variable which is correctly substituted.

Except for one thing, I don't find a way to update the value of my variable. I tried via a script called at the begining of my Deploy to change it (global plan variable) "set bamboo_releaseDate=20140622" but this doesn't work.

I tried to change an environment variable, and access it in bamboo in the Artifact download ${system.bamboo_releaseDate}. It gets the system variable, but if I update it, it doesn't take the change into account. The new value is only taken if I restart the service of my bamboo.

So I have more a configuration/best practice question. What should be the way to have dynamic variable ? What do you suggest ? Can I use the task mentionned above, or should I change completely ?

Thanks for your help !

You should be able to run these commands in a step -

set TODAY=%year%%month%%day%

Then run a step "Inject Bamboo Variables from file", where you reference the variable stored in the first step -


Then in a 3rd step set TODAY by doing the following -

for /f "tokens=2-4 delims=/ " %%a in ('date /T') do set year=%%c
for /f "tokens=2-4 delims=/ " %%a in ('date /T') do set month=%%a
for /f "tokens=2-4 delims=/ " %%a in ('date /T') do set day=%%b
set TODAY=%year%%month%%day%

Then you can reference TODAY variable (say in your copy step) with the following -


which would append the version of the app and the build number to the YYYYMMDD, i.e. 20140623_1.5.8_21

As a Belgian, beer-lover and home brewer, beer is one of my great passions. I love the fact that with just a few ingredients (usually just water, hop and malt) you can create so many different tastes...
