准备

  1. Spring Boot 的可以执行 jar 包叫 bootJar，用于依赖的 Plain jar 叫 jar
  2. 在项目设置中添加两个 Actions secrets
USERNAME：GitHub 用户名
GITHUB_TOKEN：GitHub 的 token，有读写删 packages 的权限

Gradle Config

plugins {
    ...
    id 'maven-publish'
}

...

bootJar {
    enabled = false
    archiveClassifier = 'boot'
}

jar {
    enabled = true
    archiveClassifier = ''
}

publishing {
    repositories {
        maven {
            name = "GitHubPackages"
            url = uri("https://maven.pkg.github.com/xutingzhou/gradle-lib-demo")
            credentials {
                username = System.getenv("USERNAME")
                password = System.getenv("GITHUB_TOKEN")
            }
        }
    }
    publications {
        gpr(MavenPublication) {
            artifact jar  //Spring Boot 的用于依赖 jar
          //artifact bootJar //Spring Boot 的可执行 jar
        }
    }
}

action.yml

name: Publish package to GitHub Packages
on:
  release:
    types: [created]
jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-java@v2
        with:
          java-version: 11
          distribution: adopt
      - name: Validate Gradle wrapper
        uses: gradle/wrapper-validation-action@v1
      - name: Make gradlew executable
        run: chmod +x ./gradlew
      - name: Publish package
        uses: gradle/gradle-build-action@v2
        with:
          arguments: publish
        env:
          USERNAME: ${{ secrets.USERNAME }}
          GITHUB_TOKEN: ${{ secrets.PUBLISH_TOKEN }}

需要将 gradlew 设置可执行，不然会报错

- name: Make gradlew executable
  run: chmod +x ./gradlew

报错信息

/home/runner/work/\_temp/cf1a2363-0c16-47df-b928-cfef31860ce6.sh: line 1: ./gradlew: Permission denied
或者
Error: Gradle script '/home/runner/work/gradle-lib-demo/gradle-lib-demo/gradlew' is not executable.

默认打包用于依赖的 jar 的命名会添加 plain，需要将命名中的 plain 去掉，才能在引用依赖的时候正确下载 jar 包

jar {
    archiveClassifier = ''
}
