Compiling with multiple scala versions - scala

Question

I wanted to run travis build against two Scala versions (2.12, 2.13) i.e crossCompilation, so I created two jobs for it, as logs were huge and there is a log limit of 4 MB in travis. So I created two jobs for it.Here is my travis.yml file. I am not so good with travis-ci. So I am struggling to run two jobs with different scala versions. Here is my travis.yml file:
language: scala
jdk:
- openjdk11
if: tag IS blank
services:
- mysql
addons:
apt:
sources:
- mysql-5.7-xenial
packages:
- mysql-server
dist: bionic
sudo: required
before_install:
- echo -e "machine github.com\n login $GITHUB_AUTH_TOKEN" > ~/.netrc
- mysql -e 'CREATE DATABASE IF NOT EXISTS $ZZ_API_TEST_DB_NAME;'
- sudo mysql -e "use mysql; update user set authentication_string=PASSWORD('') where user='$ZZ_API_DB_USERNAME'; update user set plugin='mysql_native_password';FLUSH PRIVILEGES;"
- sudo mysql_upgrade -u $ZZ_API_DB_USERNAME
- sudo service mysql restart
git:
depth: false
env:
global:
- ZZ_API_DB_HOST="localhost:3306"
- ZZ_API_TEST_DB_NAME=issue_management_test
- ZZ_API_DB_USERNAME=root
- ZZ_API_DB_PASSWORD=""
- SCALA_2_12="2.12.8"
- SCALA_2_13="2.13.3"
before_cache:
- find $HOME/.ivy2 -name "ivydata-*.properties" -delete
- find $HOME/.sbt -name "*.lock" -delete
cache:
directories:
- $HOME/.sbt/boot/scala*
- $HOME/.sbt/cache
- $HOME/.sbt/launchers
- $HOME/.ivy2/cache
- $HOME/.coursier
stages
- version_2.12
- version_2.13
jobs:
include:
- stage: version_2.12
name: "2.12.8"
script:
- if [ "$TRAVIS_EVENT_TYPE" == "cron" ]; then sbt coverage $SCALA_2_12 test ; else sbt $SCALA_2_12 test; fi
after_success:
- sbt coverageReport coverageAggregate
deploy:
- provider: script
skip_cleanup: true
script: sbt publish
on:
all_branches: true
condition: $TRAVIS_BRANCH != master || $TRAVIS_BRANCH != develop
- provider: script
skip_cleanup: true
before_deploy:
- travis/before_deploy.sh
script: sbt publish
on:
branch: develop
- provider: script
skip_cleanup: true
script: travis/release.sh
on:
branch: master
- stage: version_2.13
name: "2.13.3"
script:
- if [ "$TRAVIS_EVENT_TYPE" == "cron" ]; then sbt coverage $SCALA_2_13 test ; else sbt $SCALA_2_13 test; fi
after_success:
- sbt coverageReport coverageAggregate
deploy:
- provider: script
skip_cleanup: true
script: sbt publish
on:
all_branches: true
condition: $TRAVIS_BRANCH != master || $TRAVIS_BRANCH != develop
- provider: script
skip_cleanup: true
before_deploy:
- travis/before_deploy.sh
script: sbt publish
on:
branch: develop
- provider: script
skip_cleanup: true
script: travis/release.sh
on:
branch: master
I am not much familiar with travis, somehow its not picking
- SCALA_2_12="2.12.8"
- SCALA_2_13="2.13.3"
and this command:
- if [ "$TRAVIS_EVENT_TYPE" == "cron" ]; then sbt coverage $SCALA_2_12 test ; else sbt $SCALA_2_12 test; fi
is failing in travis build.
How to specify two different scala versions for these two different task, someone please help on this

Answer 1

It worked finally, this change I did,
changed $SCALA_2_13 to ++$SCALA_2_13
