Bamboo predefined variable getting overwritten

Kent Rollins

I have a build with multiple repositories so I'm using a plan variable to define the branch name so that all the repositories get checked out on the same branch for the build.

I defined a plan variable "repobranch". Each repository's branch field is set to ${bamboo.repobranch}. And I set the branch value for this variable on each branch of the plan. This all works great.

But then I wanted to use the branch name in my ant build scripts so I set an environment variable for the build: bamboo_branch=${bamboo.repository.branch.name}.

Now when the build runs, I get the following lines at the start of each task:

command	10-Oct-2013 16:32:27	Substituting variable: ${bamboo.buildNumber} with 110
command	10-Oct-2013 16:32:27	Substituting variable: ${bamboo.repository.branch.name} with ${bamboo.repobranch}
command	10-Oct-2013 16:32:27	Substituting variable: ${bamboo.build.working.directory} with C:\build\xml-data\build-dir\SFB-BAO-JOB1

So when I echo out ${ENV.bamboo_branch} in ant, the value is "${bamboo.repobranch}". That's the literal value that echos out.

I tried removing the repobranch variable from the whole plan and all branches on the plan, running it, then putting it back, but this problem is still occurring.

Any tips?

Hi,

Bamboo does not interpret variables recursively. In other words if you use variable to define another variable it won't work. That includes built-in variables that derive their value from configuration fields.

My question is why don't you just export

bamboo_branch=${bamboo.repobranch}

That should work exactly as you expect.
