Gitlab CI/CD with docker:stable as base image, install JDK but /bin/sh: eval: line 155: java: not found upon java --version

Question

I would like to invoke the java command as part of a Gitlab pipeline.

The pipeline looks like:

build:
  image: docker:stable
  stage: build
  script:
    - wget https://download.oracle.com/graalvm/23/latest/graalvm-jdk-23_linux-x64_bin.tar.gz
    - tar -xvf graalvm-jdk-23_linux-x64_bin.tar.gz
    - mv graalvm-jdk-23.0.1+11.1 /opt/
    - JAVA_HOME='/opt/graalvm-jdk-23.0.1+11.1'
    - PATH="$JAVA_HOME/bin:$PATH"
    - echo $PATH
    - export PATH
    - java --version
# // later here will download maven, compile a graalvm native image, and docker push it
  variables:
    DOCKER_HOST: tcp://docker:2376
    DOCKER_TLS_CERTDIR: "/certs"
    DOCKER_TLS_VERIFY: 1
    DOCKER_CERT_PATH: "$DOCKER_TLS_CERTDIR/client"
  services:
    - docker:dind

However, when trying to execute the java command, I am getting: /bin/sh: eval: line 155: java: not found

I tried moving the folder, chmod 777, providing relative, absolute path, but always getting /bin/sh: eval: line 155: java: not found.

I was expecting this step, the invocation of java --version to succeed.

How to invoke java command properly?

Answer 1

I would suggest to use graalvm image directly instead of slim docker image

graalvm and sdkman

In download page there are container options already, you can see both images with maven work below

variables:
  DOCKER_HOST: tcp://docker:2376
  DOCKER_TLS_CERTDIR: "/certs"
  DOCKER_TLS_VERIFY: 1
  DOCKER_CERT_PATH: "$DOCKER_TLS_CERTDIR/client"

services:
  - docker:dind

stages:
  - build

build-with-native-image:
  stage: build
  image: container-registry.oracle.com/graalvm/native-image:23
  script:
    - microdnf install unzip zip findutils
    - java --version
    - native-image --version
    - curl -s "https://get.sdkman.io" | bash
    - source "$HOME/.sdkman/bin/sdkman-init.sh"
    - sdk install maven
    - mvn package

# Job using the JDK container
build-with-jdk:
  stage: build
  image: container-registry.oracle.com/graalvm/jdk:23
  script:
    - microdnf install unzip zip findutils
    - java --version
    - curl -s "https://get.sdkman.io" | bash
    - source "$HOME/.sdkman/bin/sdkman-init.sh"
    - sdk install maven
    - mvn test

Running example here

docker image

The problem in the yml is using docker:stable which is stripped from everything, even glibc does not exist in the container, So below you can see debian based docker image and do the firther steps with scripts

build:
  image: debian:bullseye-slim
  stage: build
  script:
    - apt-get update && apt-get install -y wget tar
    - wget https://download.oracle.com/graalvm/23/latest/graalvm-jdk-23_linux-x64_bin.tar.gz
    - tar -xvf graalvm-jdk-23_linux-x64_bin.tar.gz
    - mv graalvm-jdk-23.0.1+11.1 /opt/
    - JAVA_HOME=/opt/graalvm-jdk-23.0.1+11.1
    - export PATH="$JAVA_HOME/bin:$PATH"
    - /opt/graalvm-jdk-23.0.1+11.1/bin/java --version
    - java --version
# // later here will download maven, compile a graalvm native image, and docker push it
  variables:
    DOCKER_HOST: tcp://docker:2376
    DOCKER_TLS_CERTDIR: "/certs"
    DOCKER_TLS_VERIFY: 1
    DOCKER_CERT_PATH: "$DOCKER_TLS_CERTDIR/client"
  services:
    - docker:dind
