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私服仓库
            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

四、遇见的问题

有时候会出错，如下输出

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。
