修改 Sonatype Nexus Repository Manager 发布 scope 为 runtime

(Updated: )

问题描述

如果 library 依赖其他 library，则向 maven 仓库发布时，其 pom 文件会有相应的声明:

1
2
3
4
5
6
<dependency>
  <groupId>com.yeuban</groupId>
  <artifactId>lib_child</artifactId>
  <version>1.0.0</version>
  <scope>runtime</scope>
</dependency>

其中 scope 表示依赖的 library 的编译模式:

  • runtime: 表示该 library 不会参与编译，但会参与打包。对应 Android gradle 的 compileOnly
  • compile: 表示该 library 会参与编译和打包。对应 Android gradle 中的 implementation 和 api

而向内网 Nexus Repository Manager 发布 library 时，其默认生成的 scope 为 compile，哪怕 gradle 编译的配置是 compileOnly。

解决方案

解决方法参考: https://www.droidship.com/posts/uploading_an_android_library_on_jcenter/

手动编写 pom 文件生成的内容，可以解决上述问题。
