Kamil Wasilewski commented on BEAM-10316:
-----------------------------------------
While it's definitely undesirable, I think this is an expected behaviour (and
not only limited to Python containers).
For example, take a look at
https://ci-beam.apache.org/job/beam_PostCommit_Python37/2514/consoleFull#gradle-task-79.
Gradle creates Python 2.7 environment even though it's unnecessary, because
this particular job uses Python 3.7. Here's a relevant log:

As you can see, actually _two_ virtual environments are being created. From
what I know, this defect affects all gradle tasks.
> Python container builds always create Python 2.7 environment
