如何行家清单添加到AAR指定的依赖

问题描述 投票：5回答：1

我（终于）能在我的Android库发布使用this指南的AWS S3 Maven仓库。它已作为一个AAR，而不是JAR文件，这意味着，即使产生POM文件列出其所有的内部依赖关系，他们增加了库到另一个项目时忽略。似乎是一个非常普遍的问题。我从this，我只需要列出一个清单的Maven的依赖理解，但如何做到这一点？

我真的在这一个新手，所以越简单越好...谢谢！

注：我也发现this问题，所以我补充说：“{传递=真}”的依赖实现线的末端，它的工作。

所以现在成功包括我的图书馆，依赖必须被编码为：

implementation (group: 'com.mygroup', name: 'my_library', version: '1.3', ext: 'aar', classifier: 'release') { transitive=true changing=true }

（我列入“改变=真”，以迫使它每次都重新下载库）。

如果我不包括“传递=真”，我得到了以下错误：

下面是我用来发布库（注意，只出版发行版本，但将相关线路仍然需要“释放”分类）最新的脚本：

    apply plugin: 'maven-publish'

    group = 'com.mydomain'
    version = '1.3'

    // Add sources as an artifact
    task sourceJar(type: Jar) {
        from android.sourceSets.main.java.srcDirs
        classifier "source"
    }

    // Loop over all variants
    android.libraryVariants.all { variant ->
        if (variant.buildType.name == "release") { // only release build
        variant.outputs.all { output ->
            // This creates a publication for each variant
            publishing.publications.create(variant.name, MavenPublication) {
                // The sources artifact from earlier
                artifact sourceJar

                // Variant dependent artifact, e.g. release, debug
                artifact source: output.outputFile, classifier: output.name

                // Go through all the dependencies for each variant and add them to the POM
                // file as dependencies
                pom.withXml {
                    final dependenciesNode = asNode().appendNode('dependencies')

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

                        final dependencyNode = dependenciesNode.appendNode('dependency')
                        dependencyNode.appendNode('groupId', dep.group)
                        dependencyNode.appendNode('artifactId', dep.name)
                        dependencyNode.appendNode('version', dep.version)
                        dependencyNode.appendNode('scope', scope)

                        if (!dep.transitive) {
                            // If this dependency is transitive, we should force exclude all its dependencies them from the POM
                            final exclusionNode = dependencyNode.appendNode('exclusions').appendNode('exclusion')
                            exclusionNode.appendNode('groupId', '*')
                            exclusionNode.appendNode('artifactId', '*')
                        } else if (!dep.properties.excludeRules.empty) {
                            // Otherwise add specified exclude rules
                            final exclusionNode = dependencyNode.appendNode('exclusions').appendNode('exclusion')
                            dep.properties.excludeRules.each { ExcludeRule rule ->
                                exclusionNode.appendNode('groupId', rule.group ?: '*')
                                exclusionNode.appendNode('artifactId', rule.module ?: '*')
                            }
                        }
                    }

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

    // Ensure that the publish task depends on assembly
    tasks.all { task ->
        if (task instanceof AbstractPublishToMaven) {
            task.dependsOn assemble
        }
    }

    // Configure the destination repository with
    // S3 URL and access credentials
    publishing {
        // Properties properties = new Properties()
        // properties.load(file('maven.properties').newDataInputStream())

        repositories {
            maven {
                url "s3://androidsdk.mydomain.com.s3.amazonaws.com"
                credentials(AwsCredentials) {
                    accessKey "myaccesskey"
                    secretKey "mysecretkey"
                }
            }
        }
    }

下面是在图书馆的gradle.build文件的依赖关系：

    dependencies {
        api fileTree(include: ['*.jar'], dir: 'libs')
        api 'com.android.support:appcompat-v7:27.1.1'
        api 'com.android.support.constraint:constraint-layout:1.1.3'
        api 'com.android.support:design:27.1.1'
        api 'io.reactivex.rxjava2:rxandroid:2.1.0'
        api 'io.reactivex.rxjava2:rxjava:2.2.4'
        api 'com.github.instacart.truetime-android:library-extension-rx:3.3'
        api 'com.google.dagger:dagger-android:2.15'
        annotationProcessor 'com.google.dagger:dagger-android-processor:2.15'
        annotationProcessor 'com.google.dagger:dagger-compiler:2.15'
        api 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
        api 'com.google.firebase:firebase-core:16.0.7'
        api 'com.google.firebase:firebase-messaging:17.3.4'
    }

我在想，下面的生成POM文件可能不符合图书馆的依赖关系，但他们做的。在POM文件中的“范围”的标签应移除“传递=真”的权利的需要？

您应该能够通过更改POM生成XML来解决这一点，以便<packaging>部分是设置为aar而非pom：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.humanvideoboard</groupId>
  <artifactId>hvb_library</artifactId>
  <version>1.0</version>
  <packaging>aar</packaging>

然而，现在我重新审视这个，构建库或建筑物所使用的库的事情时，当它为什么与transitive依赖工作的原因是通过使用implementation的VS api。如果您的库从它的依赖暴露类型，它的公共API的一部分，那么这些编译依赖需要在您的库构建正确处理。见this page以获取更多信息。
