gradle使用maven-publish发布jar包到私有Maven

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
