Gradle上传sources.jar和aar到jfrog artifactory。 artifactoryPublish 将生成两个 pom-default.xml，它会随机推送其中一个

Question

我有一个使用 kotlin 的 android 项目，它包含一个库模块，我想将这个库上传到 jfrog artifactory。我已成功将 aar 文件上传到 artifactory。现在我想上传 library-sources.jar 到 artifactory。但是当我执行gradle任务artifactoryPublish时，它会生成两个pom-default.xml文件，并随机发布其中一个。

项目build.gradle

    buildscript {
      ext.kotlin_version = "1.4.30"
      repositories {
        maven {
            url "http://localhost:8081/artifactory/my_virtual_repo/"
        }
      }
      dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

        classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4.15.2"
      }
    }
    allprojects {
      repositories {
          maven {
              url "http://localhost:8081/artifactory/my_virtual_repo/"
          }
      }
    }

如何上传给定的 pom 文件（如 aar_pub 的 pom-default）？谢谢。

Answer 1

单个 Publication 包含单个版本的所有工件。

您定义了两个相同的 Publications（好吧，两者都有 aar 和 pom，只有其中一个有源 JAR）并试图将它们同时上传到相同的坐标。

不要为 aar、jar、pom 中的每一个都定义一个 Publication。
将所有神器合并为一个Publication。

你的情况：

publishing {
    publications {
        mavenJava(MavenPublication) {
            groupId = GROUP_ID
            artifactId = ARTIFACT_ID
            version = VERSION_NAME

            artifact tasks.sourcesJar
            artifact("$buildDir/outputs/aar/${project.getName()}-release.aar")

            pom.withXml {
                def dependencies = asNode().appendNode("dependencies")
                configurations.api.allDependencies.each {
                    def dependency = dependencies.appendNode("dependency")
                    print(it.group)
                    dependency.appendNode("groupId", it.group)
                    dependency.appendNode("artifactId", it.name)
                    dependency.appendNode("version", it.version)
                }
            }
        }
    }
}

artifactoryPublish {
    publications("mavenJava")
}

潜在问题

出版物与生成 AAR 的任何任务之间没有正式关系。您必须在 publish 之前手动执行 assemble。（记得每次都这样做。）

考虑迁移到 Android Gradle 插件 3.6.0 或更高版本，它本身支持 maven-publish 插件。参见 documentation。这有以下好处：

您不必手动将依赖项写入 POM。
每当 AAR 更改时，出版物都会自动选取。（您无需在干净构建后发布 nothing。您不必在 publish 之前手动执行 assemble。）
在将 withSourcesJar() 支持添加到 AGP 之前，您仍然需要处理源 JAR。参见 issue。

在你的情况下它看起来像这样：

// Because the components are created only during the afterEvaluate phase, you must
// configure your publications using the afterEvaluate() lifecycle method.
afterEvaluate {
    publishing {
        publications {
            mavenJava(MavenPublication) {
                // Applies the component for the release build variant.
                from components.release
                artifact tasks.sourcesJar

                groupId = GROUP_ID
                artifactId = ARTIFACT_ID
                version = VERSION_NAME
            }
        }
    }

    artifactoryPublish {
        // ...
    }
}

Gradle upload sources.jar and aar to jfrog artifactory. artifactoryPublish will generate two pom-default.xml, it will pushlish one of them randomly
