One step in my Azure DevOps pipeline requires Java to be installed on the agent.
I found the "Java Tool Installer" task here:
This looks, however, more like a SDK installer. I only need a Java runtime environment. I am looking for something like the Python installer task:
steps:
- task: UsePythonVersion@0
inputs:
versionSpec: '3.6'
Is there anything for Java getting close to this?
Is there anything for Java getting close to this?
Test with the Python installer task, this task is used to specify a specific python version via setting the environment.
To achieve a similar purpose with Java, you could set the Java_Home and Path variable during the runtime.
You could add a powershell task at the first step.
Here is an example:
- task: PowerShell@2
inputs:
targetType: 'inline'
script: |
echo "##vso[task.setvariable variable=JAVA_HOME]$(JAVA_HOME_11_X64)"
echo "##vso[task.setvariable variable=PATH]$(JAVA_HOME_11_X64)\bin;$(PATH)"
The $(JAVA_HOME_11_X64) variable is an environment variable.
You could check this variable with the script env | sort. Then the supported value will list in the output.
For example:
In this case, the JAVA_HOME variable will be set as the expected value.
Hope this helps.
Since Azure supports Docker, I would simply go for docker:
trigger:
- main
pr:
- main
- releases/*
pool:
vmImage: 'ubuntu-20.04'
container: adoptopenjdk:latest
steps:
- script: ./gradlew check
