I wouldn't expect, that foreign JDKs are fetched: @remotejdk11_macos, @remotejdk11_macos, @remotejdk11_win and @remotejdk11_linux_ppc64le.

@comius I still see some strange fetching of alien remote JDKs on Bazel@HEAD (d258263).

To reproduce, clone Gerrit Code Review, and clone code-owners plugin into gerrit's plugins directory, then run this bazel query command:

  $ bazel query 'somepath(plugins/code-owners/java/com/google/gerrit/plugins/codeowners/validation:validation, plugins/code-owners/...)'

I am on Linux, so that I wouldn't expect alien remote JDKs to be fetched.

Environment:

  $ uname
  Linux wizball 5.10.3-1-default

  $ java -fullversion
  openjdk full version "11.0.9.1+1-suse-1.1-x8664"

[comius]

This is expected. Bazel query has to resolve all paths in a select. cquery won’t download foreign OSes. This will improve after incompatible flag is removed, because selects will go away and because query doesn’t traverse toolchain definitions.

[elasti-liranm]

@comius Which incompatible flag are you referring to?
