如何将maven清单添加到指定依赖关系的AAR

如何将maven清单添加到指定依赖关系的AAR

我(最终)能够使用本指南将我的Android库发布到AWS S3 maven存储库.它作为AAR而不是JAR文件发布,这意味着即使生成的POM文件列出了其所有内部依赖项,在将库添加到另一个项目时也会忽略它们.似乎是一个非常常见的问题.我从知道这个,我只需要列出一个清单的Maven的依赖关系,但如何做到这一点？

我真的是新手,所以越简单越好......谢谢!

注意:我也发现了这个问题,所以我在依赖实现行的末尾添加了"{transitive = true}"并且它有效.

所以现在要成功包含我的库,依赖项必须编码为:

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

(我包括"changing = true"以强制它每次重新下载库.)

如果我不包含"transitive = true",我会收到以下错误:

这是我用来发布库的最新脚本(注意它只发布了发布版本,但依赖行仍然需要"发布"分类器):

我以为下面生成的POM文件可能与库的依赖项不匹配,但它们确实如此.POM文件中的"范围"标签应该不再需要"transitive = true"吗？

您应该能够通过更改 POM XML 生成来解决此问题，以便该<packaging>部分设置为aar而不是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">

  <groupId>com.humanvideoboard</groupId>
  <artifactId>hvb_library</artifactId>

然而，现在我正在重新检查这一点，它与依赖项一起工作的原因是在构建库或构建正在使用该库的东西时transitive使用implementationvs 。api如果您的库将其依赖项中的类型作为其公共 API 的一部分公开，那么需要在您的库构建中正确处理这些构建依赖项。请参阅此页面了解更多信息。
