Gradle概念

Gradle是一个完全开源的构建自动化系统，它使用您在Apache Maven和Apache Ant上看到的概念。它使用基于编程语言Groovy 的特定于域的语言，将其与Apache Maven区分开来，后者使用XML进行项目配置。它还通过使用有向无环图确定任务的顺序。一些开发人员创建了Gradle并于2007年首次发布，并且在2013年，它被Google采用为Android项目的构建系统。它旨在支持预计会非常庞大的多项目构建。它还允许逐步添加到您的构建中，因为它知道项目的哪些部分已更新。不再重新执行依赖于更新部件的任务。目前，最新的稳定版本是5.x版本。它支持使用Java，Scala和Groovy进行开发和后续部署，以及将来引入的其他项目工作流程和语言。

Gradle下载与安装

在网址中选择一个版本下载，由于万能的强。。可能有点慢，用迅雷速度还能接受的范围
http://services.gradle.org/distributions/

接下来是环境变量中的配置
- GRADLE_HOME D:\IDEInstall\gradle-4.8
- Path %GRADLE_HOME%\bin
  
  image.png
  image.png
还有一个是本次仓库的配置，一起写了：
- GRADLE_USER_HOME D:\IDEInstall\RepGradle
  
  image.png
接下来是测试：gradle -v 或者-version也可以

这就安装成功了

Gradle 的build命令

下面是在命令行使用gradle build命令生成一个spring boot的Demo

D:\workspace\IntellijIDEA\springweb>gradle build
Starting a Gradle Daemon (subsequent builds will be faster)

IDEA 中配置

切换阿里镜像源

在init.d(里面只有个readme.txt)文件夹中建立一个init.gradle文件

image.png

添加：

allprojects{
    repositories {
        def REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public/'
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."
                    remove repo
                }
            }
        }
        maven {
            url REPOSITORY_URL
        }
    }
}

这就好了，在build的时候会发现下载路径改成了ali的maven仓库

尚未解决的问题：

我的情况是这样的，配置好了运行springboot主类的时候给我报一个找不到log4j2的错误，由于我是初步接触Gradle，所以，若有大佬路过，提提建议。。。。。

这是错误日志
