Answer 1

1. 打开项目的 build.gradle 文件。

2. 添加对 Maven 插件的引用: 应用插件:'maven-publish'

3. 在发布部分，指定包属性(生成的包名称将为 groupId:artifactId)。比如我们要发布一个.jar文件(为了篇幅，减少了章节内容):

publishing {
    publications {
        maven(MavenPublication) {
            groupId = 'org.company'
            artifactId = 'sample'
            version = "0.9-SNAPSHOT"
            from components.java

            pom {
                description = 'A description of my library'
                ...
            }
        }
    }
}
