Update travis tests to use stages + add support for java 8, 9, 10 & 11

[lili2311]

Expected behaviour

The code is tested on various java & sbt versions

Actual behaviour

Only default java version is tested with various sbt versions

Example

Here is an example travis config that would be ideal: https://github.com/snyk/snyk-gradle-plugin/pull/84/files

@lili2311,
I can take this, if that's okay.

[lili2311]

Please do :)

Just let me know what sbt versions are supported so I can have a baseline to start with?
Maybe we can decide in this ticket what matrix travis should have before I jump into it?

[lili2311]

Yep of course forgot to add this in: 0.13 1.2.8

Following with a similar pattern as to the mvn-plugin, does this look okay?

stage 1 (current sbt version - 1.2.8):

node 6 => java 9
node 8 => java 10
node 10 => java 11

stage 2 (0.13 + 1.2.8)

node 8 => java 8 (0.13)
node 8 => java 10 (0.13)
node 8 => java 11 (0.13)
node 8 => java 8 (1.2.8)
node 8 => java 12 (1.2.8)
node 8 => java 13 (1.2.8)

Not sure it is worth testing 0.13 + java 13 / java 12 maybe 1.2.8 instead? otherwise 👍

[sfat]

Yeah, makes sense :) I’ve updated the list

Should I use sdkman for this?
I see that sdkman only know from 0.13.9, while one of the test projects is set to sbt.version=0.13.7 (looking at snyk-sbt-plugin/test/fixtures/testproj-0.13/project/build.properties)

sdk list sbt
================================================================================
Available Sbt Versions
================================================================================
     1.3.0-RC1           1.1.0
     1.2.8               1.0.4
     1.2.7               1.0.3
     1.2.6               1.0.2
     1.2.5               1.0.1
     1.2.4               1.0.0
     1.2.3               0.13.18
     1.2.1               0.13.15
     1.2.0               0.13.13
     1.1.6               0.13.12
     1.1.5               0.13.11
     1.1.4               0.13.9
     1.1.3
     1.1.2
     1.1.1

Is that okay or look at https://github.com/paulp/sbt-extras ? I see that is being used in the current travis setup.

[lili2311]

So the test fixtures already pin the sbt e.g. https://github.com/snyk/snyk-sbt-plugin/blob/master/test/fixtures/testproj-noplugin-0.13/project/build.properties
so the travis setup can just be about java versions. Unless we completely restructure the tests to use system sbt version which can be another time!

Should verified before, getting repos mixed up
