The following workflow file should work, the matrix dynamic value should be evaluated after the first job is done and passed to matrix of second job.

Actual behaviour

Matrix is not evaluated

Workflow and/or repository

workflow 
name: "Dynamic Matix"

on:
  pull_request:
  push:

jobs:
  bar:
    name: Bar
    runs-on: ubuntu-latest
    steps:
      - id: output_data
        run: |
          echo '::set-output name=matrix::"{"package": ["a", "b"]}"'
    outputs:
      matrix: ${{ steps.output_data.outputs.matrix }}

  foo:
    name: Foo
    needs: [ bar ]
    runs-on: ubuntu-latest
    strategy:
      matrix: ${{ fromJson(needs.bar.outputs.matrix) }}
    steps:
      - name: foo ${{ matrix.package }}
        run: |
          echo 'Matrix "${{ matrix.package }}" JSON: ${{ toJSON(matrix) }} ${{ needs.bar.outputs.matrix }}'

@ChristopherHX commented on GitHub (Jan 14, 2022):

The output of this line doesn't seem to work for me with actions/runner

         echo '::set-output name=matrix::"{"package": ["a", "b"]}"'

It stores value "{"package": ["a", "b"]}" in output matrix => syntax error after evaluating the matrix.
I need to change it to

         echo '::set-output name=matrix::{"package": ["a", "b"]}'

Any update?

Actually no, at least not for nektos/act. I can confirm this bug in act. After fixing the error above, you can use my runner.server utillity to execute it locally like you would expect. I know that my utillity is slower than act, but faster than GitHub Actions.

<!-- gh-comment-id:1013503758 --> @ChristopherHX commented on GitHub (Jan 14, 2022): The output of this line doesn't seem to work for me with actions/runner ``` echo '::set-output name=matrix::"{"package": ["a", "b"]}"' ``` It stores value `"{"package": ["a", "b"]}"` in output matrix => syntax error after evaluating the matrix. I need to change it to ``` echo '::set-output name=matrix::{"package": ["a", "b"]}' ``` > Any update? Actually no, at least not for nektos/act. I can confirm this bug in act. After fixing the error above, you can use my [runner.server](https://github.com/ChristopherHX/runner.server) utillity to execute it locally like you would expect. _I know that my utillity is slower than act, but faster than GitHub Actions._ <Details> <Summary>Log of a run via runner.server</Summary> ``` gharun -W dyn-act.yml Starting Server...

This was fixed by #700 then broken by #763, using 0.2.24 works.

I opened a Pull Request https://github.com/nektos/act/pull/964 to provide even better dynamic matrix support as in act 0.2.24.

Including 3 tests to enshure that this feature doesn't break again without notice.

To add some more details on things that does not work related to dynamic matrix.

  1. Un-marshalling property of matrix:
jobs:
  job1:
    runs-on: ubuntu-latest
    outputs:
      matrix: ${{ steps.set-matrix.outputs.matrix }}
    steps:
      - name: get parent directory and set matrix
        id: set-matrix
        run: |
          echo "::set-output name=matrix::[\"a\",\"b\"]"

  job2:
    needs: [job1]
    runs-on: ubuntu-latest
    strategy:
      matrix:
        dirs: ${{fromJson(needs.job1.outputs.matrix)}}
    steps:
      - run: |
          echo "${{ matrix.dirs }}"

Gives:

FATA[0000] yaml: unmarshal errors:
  line 25: cannot unmarshal !!str `${{from...` into []interface {}
  1. Dynamic matrix
jobs:
  job1:
    runs-on: ubuntu-latest
    outputs:
      matrix: ${{ steps.set-matrix.outputs.matrix }}
    steps:
      - name: get parent directory and set matrix
        id: set-matrix
        run: |
          echo "::set-output name=matrix::{\"dirs\":[\"a\",\"b\"]}"

  job2:
    needs: [job1]
    runs-on: ubuntu-latest
    strategy:
      matrix: ${{fromJson(needs.job1.outputs.matrix)}}
    steps:
      - run: |
          echo "${{ matrix.dirs }}"

Simply prints empty line.

Both of those cases executes as 2 separate jobs on GHA, printing a and b.

<!-- gh-comment-id:1035013048 --> @ilons commented on GitHub (Feb 10, 2022): To add some more details on things that does not work related to dynamic matrix. 1. Un-marshalling property of `matrix`: ```yaml jobs: job1: runs-on: ubuntu-latest outputs: matrix: ${{ steps.set-matrix.outputs.matrix }} steps: - name: get parent directory and set matrix id: set-matrix run: | echo "::set-output name=matrix::[\"a\",\"b\"]" job2: needs: [job1] runs-on: ubuntu-latest strategy: matrix: dirs: ${{fromJson(needs.job1.outputs.matrix)}} steps: - run: | echo "${{ matrix.dirs }}" ``` Gives: ``` FATA[0000] yaml: unmarshal errors: line 25: cannot unmarshal !!str `${{from...` into []interface {} ``` --- 2. Dynamic matrix ```yaml jobs: job1: runs-on: ubuntu-latest outputs: matrix: ${{ steps.set-matrix.outputs.matrix }} steps: - name: get parent directory and set matrix id: set-matrix run: | echo "::set-output name=matrix::{\"dirs\":[\"a\",\"b\"]}" job2: needs: [job1] runs-on: ubuntu-latest strategy: matrix: ${{fromJson(needs.job1.outputs.matrix)}} steps: - run: | echo "${{ matrix.dirs }}" ``` Simply prints empty line. --- Both of those cases executes as 2 separate jobs on GHA, printing `a` and `b`.

@MostefaKamalLala commented on GitHub (Feb 10, 2022):

I just installed nektos/act and I experienced the same error. I have a workflow similar to @ilons 's last post's first example.

Job 1 sets up the matrix. Job 2 uses the output of Job 1 wrapped in fromJson function in the matrix definition.

Error: yaml: unmarshal errors:
  line 55: cannot unmarshal !!str `${{ fro...` into []interface {}
  line 56: cannot unmarshal !!str `${{ fro...` into []interface {}
  line 57: cannot unmarshal !!str `${{ fro...` into []interface {}
