GitHub Action : How to replace in string in file-CodePudding

Introduction

I'm currently working on a GitHub Action and I want to check if this work for many version of Java.

For this I want to update for each test the pom.xml file and change the java inside this.

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>io.github.pseudo</groupId>
    <artifactId>template</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>


    <name>template</name>
    <url>http://www.example.com</url>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>JAVAVERSION</java.version>
        <maven.compiler.source>${java.version}</maven.compiler.source>
        <maven.compiler.target>${java.version}</maven.compiler.target>
    </properties>
</project>

Question

Does someone know how we can replace string in file for each test ?

CodePudding user response：

I found this GitHub Action: MathieuSoysal/replace-string-in-file

Maybe it corresponds to your issue, it works on Macos-latest, Ubunut-latest and Windows-latest.

Example of usage for your issue

name: Test your GitHub Actions

on: [push]

jobs:

  test:
    continue-on-error: true
    strategy:
      matrix:
        java: [8, 11, 16, 17, 18, 19]
        os: [ubuntu-latest, windows-latest, macos-latest]
    runs-on: ${{ matrix.os }}

    name: Test Java version: ${{ matrix.java }} - os: ${{ matrix.os }}
    steps:
      - uses: actions/checkout@v3

      - name: Replace string in file
        uses: MathieuSoysal/[email protected]
        with:
          file: pom.xml
          old-string: JAVAVERSION
          new-string: ${{ matrix.java }}

You can use the Find and Replace GH Action to find and replace the version in your pom.xml:

name: GitHub Action

on:
  push:
    branches: [ main ]

jobs:
  build:
    strategy:
      matrix:
        java: [ '8', '11', '17' ]
        os: [ubuntu-latest, macos-latest, windows-latest]

    runs-on: ${{ matrix.os }}

    name: Java ${{ matrix.Java }} sample
    steps:
      - uses: actions/checkout@v3

      - name: Setup java
        uses: actions/setup-java@v3
        with:
          distribution: 'temurin'
          java-version: ${{ matrix.java }}

      - name: Find and Replace
        uses: jacobtomlinson/gha-find-replace@v2
        with:
          find: "JAVAVERSION"
          replace: ${{ matrix.java }}
          regex: false
          include: 'pom.xml'

      # the rest of needed steps

This WF will run a matrix with different versions of Java and replace the JAVAVERSION in the pom.xml file with the specific version.

For this example, I also used the Setup Java GH Action.
