JDK 8 and Maven missing in ARM64 despite `jdk: openjdk8`

[matthias-schn]

I am trying to a multiarch docker container with CICD using Travis ci
Travis already creates and pushed the Container into Dockerhub → but only AMD64 and I want to run it on my Raspberry either.

What is the best way to do so?

#we use java
language: java
#we add the java development kit (jdk)
jdk:
- openjdk8


matrix:
  include:
    - os: linux
      dist: xenial
      arch: amd64
      jdk: openjdk8
    - os: linux
      dist: trusty
      arch: rpi
      jdk: openjdk8
      before_install:
        - sudo apt-get -yq install maven
  
os: linux
  
virt: vm

services:
#Linking Travis CI and Docker
- docker
before_install:
- mvn clean
- echo "$DOCKER_PASSWORD" | docker login  -u "$DOCKER_USERNAME" --password-stdin
- docker pull openjdk:8-jdk-alpine
script:
#We avoid this error :" the job exceeded the maximum log length and has been terminated "
- cp .travis.settings.xml $HOME/.m2/settings.xml
- cat $HOME/.m2/settings.xml
#deploying the app on Docker
- mvn deploy

In my opinion I’d have to change something in mvn deploy but I can’t find anything like that on Google

I hope someone can help me!

Travis CI Documentation

@matthias-schn

arch:rpi

There’s no such thing as “arch:rpi”. See the documentation page for valid values.

See if there are any warnings or errors on the “config” tab of the build page.
Also check your .travis.yml at https://config.travis-ci.com/explore to see the intended resulting build matrix.

Please link to a build for me to be able to say anything else.

Are you able to access this link?: Travis CI - Test and Deploy with Confidence

The .travis.yml thing looks like this:

Oh sorry I forgot to link the docker repo… Here it is: Docker Hub
As you can see in the ‘Tags’ Tab there is only amd64

Do you mean the .travis.yml file?

I’ve confirmed the problem. For some reason, JDK 8 cannot install in an ARM64 builder.

Until the problem is solved, you can work around it by adding this to your .travis.yml (before any other commands in the before_install: section if you already have one):

before_install:
  - |
    if [[ $TRAVIS_CPU_ARCH == "arm64" ]]; then
      travis_install_jdk_package() {

        local JAVA_VERSION
        JAVA_VERSION="$1"
        sudo apt-get update -y
        PACKAGE="adoptopenjdk-${JAVA_VERSION}-hotspot"
        if ! dpkg -s "$PACKAGE" >/dev/null 2>&1; then
          if dpkg-query -l adoptopenjdk* ; then
            dpkg-query -l adoptopenjdk* | grep adoptopenjdk | awk '{print $2}' | xargs sudo dpkg -P
          fi
          wget -nv -O - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -
          sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/
          sudo apt-get update -yq
          sudo apt-get -yq --no-install-suggests --no-install-recommends install "$PACKAGE" || true
          sudo update-java-alternatives -s "$PACKAGE"*
          if ! dpkg-query -l maven &>/dev/null; then sudo apt-get -yq install maven; fi
        fi
      }
      travis_install_jdk_package 8
    fi
