Eclipse maven插件只下载JAR包，不下载AAR包
Eclipse maven plugin only download JAR package instead of AAR package
我用 Eclipse（2021-06 版）创建了一个简单的测试项目，然后 运行 Maven 构建为“-e dependency:go-offline”。
注意：我之前已经用Gradle同步了依赖，所有的工件都已经被Gradle下载了。现在我只想在测试 Maven 项目中使用该依赖项。
这里是测试项目pom.xml供参考：

但是maven插件不断请求jar:
https://mycompany.com/archiva/repository/internal/androidx/activity/activity/1.3.1/activity-1.3.1.jar
应该这样请求aar:
https://mycompany.com/archiva/repository/internal/androidx/activity/activity/1.3.1/activity-1.3.1.aar
Eclipse maven 插件是否缺少某些配置？
为什么它不下载 aar 文件？如何解决这个问题？
谢谢。
您需要显式声明包类型，如果省略类型则默认为jar。
<dependency>
<groupId>androidx.activity</groupId>
<artifactId>activity</artifactId>
<version>1.3.1</version>
<type>aar</type>
</dependency>
it should know the packaging type is "AAR"!
不应该。顺便说一句，在 pom.xml 中，您看到 <type>aar</type> 依赖项了吗？出于同样的原因。
我用 Eclipse（2021-06 版）创建了一个简单的测试项目，然后 运行 Maven 构建为“-e dependency:go-offline”。
注意：我之前已经用Gradle同步了依赖，所有的工件都已经被Gradle下载了。现在我只想在测试 Maven 项目中使用该依赖项。

但是maven插件不断请求jar:
https://mycompany.com/archiva/repository/internal/androidx/activity/activity/1.3.1/activity-1.3.1.jar
应该这样请求aar:
https://mycompany.com/archiva/repository/internal/androidx/activity/activity/1.3.1/activity-1.3.1.aar
Eclipse maven 插件是否缺少某些配置？ 为什么它不下载 aar 文件？如何解决这个问题？
谢谢。
您需要显式声明包类型，如果省略类型则默认为jar。
<dependency>
<groupId>androidx.activity</groupId>
<artifactId>activity</artifactId>
<version>1.3.1</version>
<type>aar</type>
</dependency>
it should know the packaging type is "AAR"!
不应该。顺便说一句，在 pom.xml 中，您看到 <type>aar</type> 依赖项了吗？出于同样的原因。
