这里使用最新版本的nexus3.11作为演示，nexus作为maven构建的仓库。

依赖docker

非挂载方式运行

docker run -p 8081:8081 -dti dounine/nexus /nexus/bin/nexus run

将仓库文件保存到本地方式运行

docker run -p 8081:8081 -v /xxxx/nexus/storage:/sonatype-work -dti dounine/nexus /nexus/bin/nexus run

访问http://localhost:8081
默认用户与密码：admin admin123

build.gradle

apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'maven-publish'
group 'com.dounine.nexus'
sourceCompatibility = 1.8
version = '0.0.1-SNAPSHOT'
ext {
    nexusUrl="http://localhost:8081"
    username="admin"
    password="admin123"
}
uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: "${nexusUrl}/repository/maven-releases/") {
                authentication(userName: "${username}", password: "${password}")
            }
            snapshotRepository(url: "${nexusUrl}/repository/maven-snapshots/") {
                authentication(userName: "${username}", password: "${password}")
            }
        }
    }
}

repositories {
    maven {
        if (project.version.endsWith('-SNAPSHOT')) {
            url = "${nexusUrl}/repository/maven-snapshots/"
        } else {
            url = "${nexusUrl}/repository/maven-releases/"
        }
        credentials {
            username "${username}"
            password "${password}"
        }
    }
    mavenLocal()
    mavenCentral()
}

打包代码上传到仓库

gradle uploadArchives

显示结果如下
