Use the new built-in Travis CI `jdk` constants

And while there, add OpenJDK 8 and OpenJDK 9.

💛 - Coveralls

[Stephan202]

Funny. The push builds all passed, but the openjdk-ea entry of the PR builds failed. Seems openjdk-11-ea+15_linux-x64_bin.tar.gz was deleted just now. (Retriggering the build gives the same result.)

@sormuras, should we expect the script to automatically pick up the next EA build once it becomes available? (And if so, in your experience, what's the average delay? :).)

[sormuras]

The URL points correctly to https://download.java.net/java/early_access/jdk11/15/GPL/openjdk-11-ea+15_linux-x64_bin.tar.gz which is determined from the HTML code of http://jdk.java.net/11/

Maybe +16 is about to land in just a minute...

[Stephan202]

Thanks for the rapid double-checking! We'll keep an eye on it :)

[sormuras]

Tried https://download.java.net/java/early_access/jdk11/16/GPL/openjdk-11-ea+16_linux-x64_bin.tar.gz ... and yes, that works. ✔️

When the HTML page of http://jdk.java.net/11/ is updated to jdk-11-ea+16 ... restart the failed axis.

[sormuras]

The page is still not updated. Strange...

[Stephan202]

Indeed, cause this way the page itself is also effectively broken :thinking:.

Contacted Dalibor from Oracle. He's trying to poke somebody who may help here.

In the meanwhile, we need to allow ea (11) builds to fail. https://github.com/junit-team/junit5/commit/d64f11b56c724d819d5f2c6d4529b18829fd45b1

Just after the integration into Travis CI. 😢 It worked like a charm for month now... first time I see this happen.

[Stephan202]

Several hours later: no change. Hah.

Edit: should have refreshed this browser window before posting. Thanks for the update!

[Stephan202]

@sormuras do you plan to implement an AI which automatically sends such an email and pauses the build until receiving a reply? :laughing:

[sormuras]

🤣

[sormuras]

It works like charm again. For now. :)

[Stephan202]

Yes! Thanks for raising the issue upstream :)
