read Pipeline source stage Output variables in BuildSpec

Question

Hi Team,

In my Pipeline ->  Execution History -> source

I have a section: Output variables

Key                   Value
AuthorDate	2022-03-01T10:14:36Z
BranchName	main
CommitId	9d1545410efdf085185cdfdfdbdfdce807e9a3dfd8dfd
CommitMessage	my commit message
CommitterDate	2022-03-01T10:14:36Z
RepositoryName	myRepo_name

is it possible to read those Output variables in my BuildProject->BuildSpec as env variables? so I can use their values, especially the BranchName value.

Thank you!

Accepted Answer

I did those steps :

1 - Sign in to the AWS Management Console and open the CodePipeline console at http://console.aws.amazon.com/codesuite/codepipeline/home.

2 - Choose the pipeline => choose Edit. On the stage that contains your CodeBuild action, choose Edit stage.

3- Choose the icon to edit your CodeBuild action.

4 - On the Edit action page, under Environment variables, enter the following:

- In Name, enter a name for your environment variable.

- In Value, enter the variable syntax for your pipeline output variable:  #{SourceVariables.BranchName}.
- In Type, choose Plaintext.

then in code buildSpec you access the resolved value like $VAR_NAME
