修改前：	
//repositories {
		//	mavenCentral()
	 	//	maven { url "https://repo.spring.io/libs-spring-framework-build" }
		//}
修改后：
		repositories {
			mavenCentral()
			maven { url "https://repo.spring.io/libs-spring-framework-build" }
			maven { url "https://repo.spring.io/snapshot" } // Reactor
			maven {url 'https://maven.aliyun.com/nexus/content/groups/public/'} //阿里云
			maven {url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
		}

此时编译Spring编码，Build -> Build Project
可能会报如下错误：

这里查询问题的关键点是Process ‘command ‘git’’ finished with non-zero exit value 128，推出值为128，在百度寻找半天没有一个好的解决办法，然后谷歌找到问题所在，大部分解决方案都如下

其实看到这里就能发现问题，就是idea在调度终端时发生错误，找不到git，当然windows系统为cmd，但是mac默认并不是git终端，按照上述修改方式仍然无法解决问题，因为mac终端为：/bin/sh，所以下图才是找到问题的正解：

所以找到spring工程中gradle目录下找到build-scan-user-data.gradle
将execAndGetStdout方法内容

String execAndGetStdout(String... args) {
	def stdout = new ByteArrayOutputStream()
	exec {
		commandLine(args)
		standardOutput = stdout
	}
	return stdout.toString().trim()
}

替换为

String execAndGetStdout(String... args) {
	def stdout = new ByteArrayOutputStream()
	exec {
		executable "/bin/sh"
		standardOutput = stdout;
	}
	return stdout.toString().trim()
}

然后再进行build，构建成功～

看下你本地的git是否正确安装，如果没有的话，安装下，IDEA里面配置下
