How can I run specific build based on variable?

Tarun Makhija1

I have 3 build tasks in the deploy stage of my plan- 

Clear Demo which runs
-U clean liquibase:dropAll -pl database/mysql -Pdemo

Clear Dev which runs
-U clean liquibase:dropAll -pl database/mysql -Pdev_int

Clear QA
-U clean liquibase:dropAll -pl database/mysql -Pqa

Right now, when I have to deploy in demo, I have to disable dev_int and qa.

What I want to do?
Just have one step, which picks the value from a variable e.g. WHICH_ENVIRONMENT
The value can be : demo, dev_int(default), qa

-U clean liquibase:dropAll -pl database/mysql -Pl<WHICH_ENVIRONMENT>

Is this possible?

TIA for help!

You can setup 3 environment deployments demo, dev_int, qa.

And each one has a deploy task that calls:
-U clean liquibase:dropAll -pl database/mysql -Pl${bamboo.deploy.environment}

The value of ${bamboo.deploy.environment} will be based on the environment name i.e. demo.
