this is not urgent. there is no action in 2.11 land currently, and we have the 2.11.x-jdk8 build, and if we need to do a JDK 6 run for QA purposes we can always just do it on a laptop or whatever

in the meantime, some tips for running locally on MacOS:

• brew cask install java6
• run.sh does not check the JDK version, so be sure and:
  • export JAVA_HOME=$(/usr/libexec/java_home -v 1.6)
• if you get "java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty"
  • sudo rm /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts
  • sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/jre/lib/security/cacerts /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts

UPDATE: https://github.com/SethTisue/community-builds/tree/2.11.x-jdk6-local-run has some further tweaks I'm using. (Including using a local Artifactory, it's agonizingly slow without one.)

@adriaanm I can ssh to the behemoths now, but I can't apt-get install because I can't sudo that voodoo that I do:

[sudo] password for jenkins:

[adriaanm]

jenkins can't sudo, that would be a huge security hole. You should log in as the admin user.

[adriaanm]

(no sudo make me a sandwich for you, jenkins)

regarding installing Java 6, I don't know how to get there. Oracle's distro requires a license. Old versions of OpenJDK are hard to install on modern debian.

works, thanks.

regarding installing Java 6, I don't know how to get there. Oracle's distro requires a license

uh, how is that even possible? it was free before, we had it installed before. confused

[SethTisue]

also what if we need to roll 2.11.13 (or, god forbid, 2.10.8) because of some security hole or something?

I now finally have a fully green 2.11.x/JDK6 build running locally on my Mac (see remarks above at https://github.com/scala/scala-jenkins-infra/issues/242#issuecomment-365815533), and I have an automated reminder that reminds me to run it every so often.

I think that's fine for now. We can cross the 2.11.13 bridge if we ever come to it.

having trouble letting this go...

reference on JDK 6 no longer being available via sudo add-apt-repository ppa:webupd8team/java plus sudo apt-get install oracle-java6-installer like used to work: http://www.webupd8.org/2017/06/why-oracle-java-7-and-6-installers-no.html

however Java 6 Update 45 does remain available from http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html

[SethTisue]

manually installed Java 6 Update 45 into /usr/lib/jvm

jvmSelect finds it as long as you specify the Java "flavor" as j (I thought jdk would work and it didn't so I tried j on a hunch and bingo)

changed the 2.11 job configuration to do that, and to run @daily

wiped out workspace, just in case
