steps

1. install official sbt launcher from GitHub releases
2. run sbt --client with any other CLI flags

problem

Other CLI flags are ignored. Examples:

►  ./sbt/bin/sbt --error --no-colors --client 'print version'
►  SBT_OPTS='-Dsbt.log.noformat=true' ./sbt/bin/sbt --client 'print version'
►  env SBT_OPTS='-Dsbt.color=false' ./sbt/bin/sbt --client 'print version'

All above commands print with colors ignoring any attempts to disable it, here is a screenshot:

You can also see that the --error (or -error) flag gets ignored, so I get the undesired logging.

I've tried passing arguments in different order and via SBT_OPTS, but it seems that the launcher just ignores anything when there is --client flag. Same happens with the sbtn native client.

expectation

In this concrete use case I would like to be able to print the version setting value without any logs or color codes.

In general, I think sbt should treat arguments in the client mode same way as in the batch mode:

notes

►  ./sbt/bin/sbt -version
sbt version in this project: 1.5.0
sbt script version: 1.5.0

I know that the launcher script treats "client mode" specially, but I think this functionality is essential for using sbt in scripts and integrating with other CLI tools. Running sbt in batch mode several times is too slow.
