How to change plan variable value on a script task?

Question

I have a plan variable called myCustomVar="myvalue"

I can successfully use it inside my script tasks calling it ${bamboo.myCustomVar}, however I am looking to modify the variable's value in one of the tasks. I have tried the following with no success:

* bamboo.myCustomVar="newvalue"
* myCustomVar="newvalue"
* ${bamboo.myCustomVar}="newvalue"

I have been thoroughly seeking for an answer in documentation with no success, all I have found is that we can override variables in manual builds but this will not work for my purpose,

Thank you

Hello @Vazquez, Eduardo

If you are using Windows, there's no need to replace the dots with underscores. So the "set" command will work as required with the variables set as bamboo.myCustomerVar.

Thank you for your prompt response. It seems your first paragraph pretty much describes what I am trying to do with the only exception that my task script is run on windows, would this also apply? If so I am thinking the syntax would be one of the options below:

* bamboo_myCustomerVar="newValue"
* set bamboo_myCustomerVar="newValue"

The inject bamboo variables task sounds great but for now I think the solution above should suffice should you confirm the appropiate syntax for windows.

Best regards,

Welcome to Atlassian Community!

If you are looking to only modify the variable's value in one of your tasks you will have to do that on the command line during the task execution. Also, Script tasks in Linux use the ${bamboo_myCustomerVar} syntax (with a _ instead of dots .). As described here:

* Bamboo Variables - Using variables in bash

But if you want to have a controlled experience, you can add an Inject Bamboo Variables task that would create new variables based on property files which can be used subsequently by your builds.
