gradle使用maven-publish发布jar包上传到私有maven配置

一、添加插件

apply plugin: 'maven-publish'

二、添加如下配置

//打包源码
task sourceJar(type: Jar) {
   from sourceSets.main.allJava
}
publishing {
   publications {
       maven(MavenPublication) {
           //指定group/artifact/version信息，可以不填。默认使用项目group/name/version作为groupId/artifactId/version
           groupId project.group
           artifactId project.name
           version project.version
           //如果是war包填写components.web，如果是jar包填写components.java
           from components.java
           //配置上传源码
           artifact sourceJar {
               classifier "sources"
           }
       }
   }
   repositories {
       maven {
           //指定要上传的maven * 仓库
           url = "http://jenkins.maxrocky.com:8080/maven/content/repositories/thirdparty/"
           //认证用户和密码
           credentials {
               username 'admin'
               password 'maxrocky5721'
           }
       }
   }
}

三、执行以下命令进行上传

gradle publishMavenPublicationToMavenRepository

正常的输出结果

我的是因为网络原因，换个网络，多试几次就成功了，去stackoverflow上看了以下，没有太明确的原因。
