Playing with maven by trying to add Androidx appcompact library dependency to my hello world java maven project. I have updated my projects pom.xml by dependency:

<dependencies>

...

<dependency>

<groupId>androidx.appcompat</groupId>

<artifactId>appcompat</artifactId>

<version>1.1.0</version>

<scope>runtime</scope>

</dependency>

...

</dependencies>

and repository:

<repositories>

<repository>

<id>google</id>

<url>https://maven.google.com/</url>

</repository>

</repositories>

I have executed mvn package command and got error:

[ERROR] Failed to execute goal on project my-app: Could not resolve dependencies for project com.mycompany.app:my-app:jar:1.0-SNAPSHOT: Could not find artifact androidx.appcompat:appcompat:jar:1.1.0 in google (https://maven.google.com/)

What I did wrong?

According to maven repository package should be there.

Whole POM.XML:

<?xml version="1.0" encoding="UTF-8"?>

  • This artifact us also on maven central, so basically you can remove the 'repository' section – OhadR Dec 28 '19 at 20:31

try

mvn clean install -U

this will force update your dependencies, also check your mvn syntax in the pom file, share your complete pom file if it still doesn't work
