gradle的一些实践

发表于 分类于

gradle的一些实践，nexus的配置参考：nexus配置的一些实践

1. 认证

~/.gradle/gradle.properties 添加账号密码的变量

vim ~/.gradle/gradle.properties
nexus_user=你的账号
nexus_pwd=你的密码

2. 依赖

注意两个文件：

2.1 文件一：项目根目录的build.gradle

buildscript {
	ext {
		springCloudFrameVersion="2020.0.3"
		springCloudVersion="3.0.3"
		springBootVersion= "2.5.4"
	}
    //注意，在buildscript里添加仓库
	repositories {
		maven {
			credentials { 
                username = "${nexus_user}" 
                password = "${nexus_pwd}" 
            }
			url = "https://nexus.local.com/repository/maven-public/"
		}
	}
	dependencies {
		classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
	}
}
plugins {
	id 'io.spring.dependency-management' version '1.0.11.RELEASE'
	id 'java'
}
allprojects {
	apply plugin: 'java'
	group = 'test.lib'
	sourceCompatibility = '11'
	targetCompatibility = '11'
    tasks.withType(JavaCompile) {
        options.encoding = "UTF-8"
    }
 	//注意，在allprojects里添加仓库
	repositories {
		maven {
			credentials { 
                username = "${nexus_user}" 
                password = "${nexus_pwd}" 
            }
			url = "https://nexus.local.com/repository/maven-public/"
		}
	}
	dependencyManagement {
		imports {
			mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudFrameVersion}"
		}
	}
}
subprojects {
	apply from: '../global_config.gradle'
}

2.2 文件二：setting.gradle

// 注意，必须放在文件头
pluginManagement {
    repositories {
        maven {
            credentials { 
                username = "${nexus_user}" 
                password = "${nexus_pwd}" 
            }
            url = "https://nexus.local.com/repository/maven-public/"
        }
    }
}

注意：不要再依赖 https://nexus.local.com/repository/javaproject/ 或者 google(),maven_centre(),jencenter(),只依赖maven-public.
maven-public作为group，已经将其他仓库全部作为成员进行了合集，包括：maven-center和阿里云的仓库。
如果你额外需要jcenter或者其他仓库，应该在nexus上创建proxy，并依然由maven-public统一收束。

3. 发布

目标：

1

3
4
//通过upSnap直接发布一个snapshots的包到nexus的snapshots仓库
./gradlew clean assemble upSnap
//通过upRelease直接发布一个release的包到nexus的release仓库
./gradlew clean assemble upRelease
