Gradle 產生含 pom.xml 的 Jar 檔

Posted on 2018-05-18 由 jiayun

回覆

build.gradle 加這些：

plugins {
    id 'maven-publish'
}

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
        }
    }
}

jar {
    into("META-INF/maven/$project.group/$project.name") {
        from { generatePomFileForMavenJavaPublication }
        rename ".*", "pom.xml"
    }
}

components.java 不是指 .java 檔，不用改它

然後跑 gradle publishToMavenLocal（我現在是只先做到產生 Jar 再自己上傳到 packagecloud）

其他細節參考 https://docs.gradle.org/current/userguide/publishing_maven.html
