How to share variable value from a reusable to its caller workflow

Here is my caller workflow:

name: Dev-Release

on:
  workflow_dispatch:
 
jobs:

  BUILD:
    uses: mybank/DevOps/.github/workflows/buildmaven.yml@mybranch

  RELEASE:
    needs: [BUILD]
    runs-on: "self-hosted1755"
    steps:

      - name: Release to DEV
        run: |
          Write-Host "NEWJAVAPATH - ${{ needs.BUILD.outputs.newjavapath }} i.e $env:JAVA_HOME"

Here is my called Reusable Workflow:

on:
  workflow_call:

    outputs: 
      newjavahome:
        value: ${{ jobs.BUILD_APP.outputs.newjavahome }}

jobs:

   BUILD_APP:
      runs-on: "self-hosted1755"
       
      outputs:
        newjavahome: "${{ steps.printnewpath.outputs.newjavahome }}"
       
      steps:

        - name: Set up JDK
          uses: actions/setup-java@v3
          with:
            java-version: '8' 
            distribution: 'adopt'
        
        - name: Print JAVA Home
          id: printnewpath
          run: |
            Write-Host "NEW JAVA HOME is $env:JAVA_HOME"
            echo "newjavahome=$env:JAVA_HOME" >> "$env:GITHUB_OUTPUT"

I'm able to print NEW JAVA HOME is D:\what\ever\path\JAVA\x86 during the execution of the reusable workflow.

However, i m in need to carry this value and print it in caller workflow job named RELEASE:

Can you please suggest what am i missing?

Solution

  • It looks like you're trying to pass the JAVA_HOME value from a reusable workflow back to the caller workflow and then use it in a subsequent job. The main issue seems to be with how
    the output is being set and accessed.
