How to increment version when my plan executes?

[Arpan Mehetre]

I have a c# library which gets build and published to our package repository through a bamboo plan each time we update it in Bitbucket.

I have a plan level variable "version = 1.0.0".

I want to be able to update the value of this variable every time the plan runs. It should - 

• Pick up the existing version of library(e.g., 1.0.0 or 1.0.1 etc...)
• Increment it by 1(e.g., 1.0.2)
• And then this variable should be available for next task in the plan which is responsible for publishing the library to package repository

I have the task type -  "Version Variable Incrementer" but there is not enough documentation(that I can find) on how to use that.

Please help. Thanks.

Hi Arpan! How are you doing?

We did something similar to this using the variable ${bamboo.buildNumber}.

You could still have a variable called version with value 1.0 and pass "${bamboo.version}.${bamboo.buildNumber}" as a parameter to your tasks.

As this value will be the same during the entire build, you can use this expression anywhere you want, so you would't have to care about passing it between tasks.

Hope this helps!
