Parameterized build command

[andzuc]

Hi. It would be possible to use variable expansion in build.upstream, build.current, build.downstream ? The README is not mentioning this feature. In particular for GROUP, PROJECT and BRANCH so that it would be possible to pass current/upstream/downstream build project info to the build system.

Hi, nope we don't have any variable substitution in build.upstead, build.current or build.downstream since these are user defined commands.

IMO its on the program that utilizes build-chain-configuration-reader information to handle such variable substitutions for all these commands. For example, we use this library for github-action-build-chain whose command executor handles env variable substitution
