How can i change a bamboo variable in a script task

Question

Hi,

One of my build task it getting a variable from my pom file, the version number.  This step place the value in variable bamboo_maven_version.

Later, i have another build task, a script one, where i want to change the bamboo_maven_version

In this script :

echo "Hello $bamboo_maven_version"

set "bamboo_maven_version=0.0.11"

echo "Hello $bamboo_maven_version"

The end result is :

build	16-Sep-2016 12:33:41	Hello 0.0.10-SNAPSHOT
build	16-Sep-2016 12:33:41	Hello 0.0.10-SNAPSHOT

Is it possible to change, from a script task, a bamboo variable ?

Not being able to change the value of a variable does, well... suck. In effect, they aren't variables, but constants.

I can see why this isn't easy to implement in e.g. bash scripts etc, but there could at least be a specific task type "Change bamboo variable value", where some value could be directed into a variable.

The option to use a file "works" in certain scenarios, but so does booting from floppy.

My use case is pretty much exactly as @lance_lyons  above; I need to alter some stuff on a docker image before pushing it to repo.

There is a flow that is not covered.  If I want to produce some docker image name that was produced in a build like  servicename:1.0.0.1 and then use this image name in down stream deploys, I am not able to set this variable (eg, latestimagename) so I can use that value in a later deploy.

I could write the value to a file and then on subsequent deploys pull that file as artifact and then read that value but this is a long way from just being able to set a variable.

Has this changed in recent versions of bamboo?

I don't thinks so, looks like Inject variable task covers all flows
