Issue
I created a simple test project with Eclipse (version 2021-06), and then run Maven build as "-e dependency:go-offline".
Note: I have synchronized the dependencies with Gradle before, all artifacts have been downloaded by Gradle. Now I just want to use that dependency in the test Maven project.
Here is the test project pom.xml for reference:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

Here is the activity-1.3.1.pom that maven plugin has downloaded in the local directory:

Here is the console output for reference:
From the console, I can see that maven plugin has downloaded the pom.xml file, it should know the packaging type is "AAR"!

But maven plugin keeps request the jar:
https://mycompany.com/archiva/repository/internal/androidx/activity/activity/1.3.1/activity-1.3.1.jar
It should request the aar like this:
https://mycompany.com/archiva/repository/internal/androidx/activity/activity/1.3.1/activity-1.3.1.aar
Is there something configuration missing for the Eclipse maven plugin? Why doesn't it download aar file? How to fix this problem?
Thanks.
Solution
You need to explicitly declare package type, default is jar if type is omitted.
<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"!
No it shouldn't. Btw in very same pom.xml, do you see <type>aar</type> on dependencies ? It's there for same reaon.
