encryptionKeyOverride

The Key Management Service customer master key (CMK) that overrides the one specified in the batch build project. The CMK key encrypts the build output artifacts.

You can use a cross-account KMS key to encrypt the build output artifacts if your service role has permission to that key.

You can specify either the Amazon Resource Name (ARN) of the CMK or, if available, the CMK's alias (using the format alias/<alias-name>).
