Remove our Travis Github check

[carlspring]

Task Description

We were using Travis for our builds under MacOS. This used to work in the past, however, lately it constanly times out, simply because our complete build takes a while to complete and Travis simply kills it, if it exceeds the time. When this fails, the checks in pull requests fail.

Tasks

The following tasks will need to be carried out:

• Remove the Travis script.
• Remove our Travis hooks. (@steve-todorov ?)

Relationship:

• Relates to: Migrate Strongbox from OrientDB to JanusGraph #1649 (includes Github Actions)

Help

Regarding discussion in chat about JDK8 and the macOS build environment in Travis CI; from the docs:

While Mac jobs can test against multiple JDK versions using the jdk key, macOS images up to xcode9.3 can only switch up to Java 8

So something like this should work:

# .travis.yml

jdk:
  - oraclejdk8
  - openjdk8

script:
  - # use openjdk8 for this build
  - jdk_switcher use openjdk8

Alternatively, we can use the homebrew addon and set JAVA_HOME to this jdk.

# .travis.yml

osx_image: xcode9.3
addons:
  homebrew:
    taps: homebrew/cask-versions
    casks: adoptopenjdk8

Hey, thanks for checking into it! I've created a separate task for this #1956. If you're up for upgrading the JDK - feel free to comment under it and I'll assign it to you. :)

You can try with the jdk: [ -openjdk8 ] approach - if the JDK is >= 1.8.0_222 then it'll work. Otherwise you'll probably need to go the homebrew path.
