Modify a variable in a configuration from a build #4582

chrisnak ·

Hello everyone,

In our build system we have a requirement that we need to modify the value of a variable living in a configuration from a build that lives in a sibling configuration.


To give you more context I have this setup;

Root
    -> Branch_A
        -> Deploy
        -> Promote_A_to_B
    -> Branch_B
        -> Deploy

Each branch has a variable named "commit" with different values. So every time I run Branch_A's Deploy, Branch_A's "commit" is updated to the current commit number, while Branch_B's "commit" remains intact.

What I want to do is updating Branch_B's "commit" number when Promote_A_to_B runs.


What I've tried so far;

  1. I created a temporary build, set it's configuration as the target one, get the commit variable wrapper and set it's value as the wanted one.
def Main() 
{
    def promote_commit = vars.getValue("commit");
    def target_config_path = "Root/Branch_B";
    def configuration_obj = system.configurationManager.get( target_config_path );
    def tempBuild = new Build();

    tempBuild .setConfiguration( configuration_obj );
    def current_target_cl = tempBuild .getVar("Promote_Changelist");
    current_target_cl.setValue( promote_commit, true );
}

Result -> Branch_A's "commit" number modified, not the targeted one.

  1. I tried to set the commit value I want to the target variable by getting it from the target configuration object.
def Main()
{
    def promote_commit = vars.getValue("commit");
    def target_config_path = "Root/Branch_B";
    def configuration_obj = system.configurationManager.get( target_config_path );

    def fetched_commit = configuration_obj.findVar("commit");
    fetched_commit.setValue( promote_commit );
}

Result -> The PromoteA_to_B build has the correct "commit" values for both Branch_A and Branch_B, but Branch_B's "commit" remains the same

Does anyone have done something similar or can help?

This is pretty simple, just use below script:

groovy:

def otherConf = system.configurationManager.get("path/to/other_configuration");
system.configurationManager.saveVariable(otherConf, "var_name", "var_value");

That was simple indeed, thanks.
