How To Add Maven Dependency (Android Studio)

Question

I have this code below..

<dependency>
    <groupId>me.gujun.android.taggroup</groupId>
    <artifactId>library</artifactId>
    <version>1.4</version>
    <type>apklib</type>
</dependency>

But where do you put this in Android Studio? I've already placed a dependency in build.gradle which is compile 'me.gujun.android.taggroup:library:1.4@aar'

Answer 1

In Android Studio 3.0 and above, you can just copy

<dependency>
    <groupId>me.gujun.android.taggroup</groupId>
    <artifactId>library</artifactId>
    <version>1.4</version>
    <type>apklib</type>
</dependency>

into build.gradle, and it automatic converts it to:

implementation 'me.gujun.android.taggroup:library:1.4'

Android Studio 2020.3.1 (maybe before), they added dependencyResolutionManagement in the settings.gradle. So if you put something in build.gradle the default was to not search the added repository and fail.

One solution is to add your additional repository to the settings.gradle file, and change the RepositoriesMode to PREFER_SETTINGS.

settings.gradle:

import org.gradle.api.initialization.resolve.RepositoriesMode
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS) // CHANGED THIS LINE
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
        maven { url 'https://oss.sonatype.org/content/repositories/snapshots'} // ADDED REPO
    }
}
rootProject.name = "My Application"
include ':app'

I had a similar issue just now. I was trying to use khttp in an Android app. Here's the XML that library gave me:

<repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
</repository>

...and

<dependency>
    <groupId>com.github.jkcclemens</groupId>
    <artifactId>khttp</artifactId>
    <version>-SNAPSHOT</version>
</dependency>

What I ended up doing was editing the root build.gradle file and adding this:

allprojects {
    repositories {
        maven {
            url "https://jitpack.io"
        }
    }
}

Then, I edited the app's gradle file, and added this line to the existing dependencies { .... } section:

compile 'com.github.jkcclemens:khttp:master-SNAPSHOT'

Once done, I hit the "try again" or "sync" button on the yellow bar that appeared to get Android Studio 3.0.1 to recognise the changes I'd made.

I followed the instructions on the JitPack homepage.
