sbt 1.4.0: sbt.color flag does not work on CI

[christobill]

steps

Start a new project from the scala-seed g8 template (for example)

sbt new scala/scala-seed.g8

With sbt 1.4.0-M1 and older version

export CI=true
sbt -Dsbt.color=true test

Display colors in test results

With sbt 1.4.0-M2 and latest version (including 1.4.0 release)

export CI=true
sbt -Dsbt.color=true test

Does not display colors in test results

problem

Harder to see failing tests on CI when looking at the test job result
Behavior not expected when setting flag sbt.color=true

expectation

With sbt 1.4.x

export CI=true
sbt -Dsbt.color=true test

Display colors in test results

Thanks for the report! Should be fixed by #5960

After upgrading to 1.4.2 version the coloring doesn't work. Tested via:

export SBT_OPTS="-Dsbt.color=true"
sbt test

and

export CI=true
sbt -Dsbt.color=true test

Downgrading to 1.4.1 works. Should I create a new issue or this comment is enough?

Thanks for the report. I think this should be fixed by #6061. FTR, I couldn't fully reproduce this. There were some colors printed with sbt 1.4.2 but the scalatest output was not colorized which is what #6061 fixes.
