How to bump version with GitHub Actions - bash

Question

I want to bump the version by running my shell script. I am manually triggering the GitHub Actions with inputs. I am using GitHub API to get the latest version and I want to run my shell script with the version taken from GitHub API.
I am able to achieve everything. It's just that I am not able to get the version output.
This is my GitHub Workflow:
#############################################################################
# GitHub Action to bump release version
#
#############################################################################
name: "Bump version and Update Milestone"
on:
workflow_dispatch:
inputs:
version:
description: 'New Version'
required: true
default: 'warning'
permissions:
contents: write
pull-requests: write
jobs:
printInputs:
runs-on: ubuntu-latest
steps:
- run: |
echo "Latest Version: ${{ github.event.inputs.version }}"
bump:
name: Bump version
runs-on: ubuntu-latest
steps:
- name: Checkout the latest code
uses: actions/checkout#v2
with:
token: ${{ secrets.GITHUB_TOKEN }}
- name: Get the version
id: get_version
run: |
VERSION=$(curl -s https://api.github.com/repos/checkstyle/checkstyle/releases/latest \
| jq ".tag_name")
echo VERSION="$VERSION"
- name: Modify File
run: |
./.ci/bump-version.sh ${{ steps.get_version.VERSION }}
- name: Push commit
run: |
git config --global user.name 'github-actions[bot]'
git config --global user.email 'github-actions[bot]#users.noreply.github.com'
git commit -am "minor: Bump release version to ${{ steps.get_version.VERSION }}"
git push
- name: GitHub Milestone
run: |
.ci/update-github-milestone.sh
This is my shell script:
#!/bin/bash
set -e
VERSION=$1
echo VERSION="$VERSION"
echo "bump version in pom.xml"
mvn versions:set -DnewVersion="$VERSION" && mvn versions:commit
And these is my tested actions where I want help:

To transfer an output from one step to another, you need to use a workflow command:
echo "::set-output name=VERSION::$VERSION"
and then reference it like this in a later step via the outputs object:
run: |
./.ci/bump-version.sh ${{ steps.get_version.outputs.VERSION }}
