Subject Re: [all/travis-ci] Regarding potential Travis-CI solutions
Date Sat, 05 Aug 2017 10:31:40 GMT
[I don't know anything about Travis, so this may be a non-starter.]

The ASF Jenkins jobs can be set up with environment variables that
point to different JDKs.
If there is something similar for Travis, then the script could use those.
It would then be up to the Travis maintainers to ensure that the
variables are correctly maintained.
Since they are the ones who install the JDKs, they are best placed to
maintain the variables.

Or maybe there is some config file that provides the same info?

If Travis does not provide such a feature, maybe someone should request it?
