Add Java 9 to the list of available JVM

[xcoulon]

Even thought Java 9 is not final yet, it would be great if we could build and test projects on it, especially when those projects are libraries or frameworks.

Until we update the build environment (not yet scheduled), you can do this manually.

I've enabled Oracle Java 9 (travis-ci/apt-package-safelist@d69505b). You still need to set up your environment manually, but you can use it.

On containers:

sudo: false

addons:
  apt:
    packages:
      - oracle-java9-installer

before_install:
  - remove_dir_from_path $JAVA_HOME/bin
  - export JAVA_HOME=/usr/lib/jvm/java-9-oracle
  - export PATH=$JAVA_HOME/bin:$PATH
  - java -version

On standard infrastructure:

sudo: required

before_install:
  - sudo apt-get update -qq
  - sudo apt-get install oracle-9-installer
  - remove_dir_from_path $JAVA_HOME/bin
  - export JAVA_HOME=/usr/lib/jvm/java-9-oracle
  - export PATH=$JAVA_HOME/bin:$PATH
  - java -version

Is there a way to have build matrix with Java 8 and Java 9?

[wendal]

Java 9 has been released now: https://docs.oracle.com/javase/9/

[jqno]

According to https://docs.travis-ci.com/user/languages/java/ Java 9 is available: add oraclejdk9 to the build matrix. I tried it in my project and it works.

[BanzaiMan]

Indeed.

[robinst]

Doesn't work for me. I'll raise a different issue.

Edit: Raised #8513.
