使用aar和source jar将Android库发布到Maven

Question

有人可以给我一个关于如何使用maven-publish gradle插件发布带有aar和source jar的com.android.library项目/模块的提示吗？我可以使用旧的maven插件执行此操作 - 但我想使用新的maven-publish插件.

Answer 1

这是使用新maven-publish插件的示例.

apply plugin: 'maven-publish'

task sourceJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier "sources"
}

publishing {
    publications {
        bar(MavenPublication) {
            groupId 'com.foo'
            artifactId 'bar'
            version '0.1'
            artifact(sourceJar)
            artifact("$buildDir/outputs/aar/bar-release.aar")
        }
    }
    repositories {
        maven {
            url "$buildDir/repo"
        }
    }
}

发布 ./gradlew clean build publish

Answer 2

这是我改进的解决方案,基于其他答案.

要点: https ://gist.github.com/Robyer/a6578e60127418b380ca133a1291f017

其他答案的变化:

• 改变了classifier- 一定是"sources"(不是 "source")

• 处理依赖关系

  • 支持也@aar和transitive: false.在这种情况下,我们在POM中设置排除以忽略此依赖项的所有传递依赖项.

  • 支持自定义排除依赖关系的规则,例如:

    compile('com.example:something:1.0', {
        exclude group: 'com.exclude.this', module: 'some-module'
    })
    

• 不需要手动指定工件路径.

更新日志:

• 27.3.2018 - 在新Gradle中添加了对api/implementation依赖关系的支持
• 2018年11月23日 -更名bundleRelease到bundleReleaseAar,因为它在新的摇篮改变(见这个答案)
• 23.11.2018 - 更改getAllDependencies为getDependencies修复重复的结果条目(如我的要点中的评论中所述).

                    ext.addDependency = { Dependency dep, String scope ->
                        if (dep.group == null || dep.version == null || dep.name == null || dep.name == "unspecified")

                            }
                        }

                    // List all "api" dependencies (for new Gradle) as "compile" dependencies
                    configurations.api.getDependencies().each { dep -> addDependency(dep, "compile") }
                    // List all "implementation" dependencies (for new Gradle) as "runtime" dependencies

Answer 3

对dskinners进行一些调整,回答正确的依赖关系:

apply plugin: 'maven-publish'

task sourceJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier "source"
}

publishing {
    publications {
        bar(MavenPublication) {
            groupId 'com.foo'
            artifactId 'bar'
            version '0.1'
            artifact(sourceJar)
            artifact("$buildDir/outputs/aar/bar-release.aar")
            pom.withXml {
                def dependenciesNode = asNode().appendNode('dependencies')
                //Iterate over the compile dependencies (we don't want the test ones), adding a <dependency> node for each
                configurations.compile.allDependencies.each {
                    if(it.group != null && (it.name != null || "unspecified".equals(it.name)) && it.version != null)
                    {
                        def dependencyNode = dependenciesNode.appendNode('dependency')
                        dependencyNode.appendNode('groupId', it.group)
                        dependencyNode.appendNode('artifactId', it.name)
                        dependencyNode.appendNode('version', it.version)
                    }
                }
            }
        }
    }
    repositories {
        maven {
            url "$buildDir/repo"
        }
    }
}

你可以改变version并groupId定义:

version = '1.0.0'
group = 'foo.bar'

Answer 4

如果你想避免样板代码,因为maven-publish插件不会将依赖项写入pom.xml

试试这个插件:android-maven-publish

publishing {
    publications {
        mavenAar(MavenPublication) {
            groupId 'com.example'
            artifactId 'mylibrary'
            version '1.0.0'
            from components.android
        }
    }

    repositories {
        maven {
            url "$buildDir/releases"
        }
    }
}
