Android with maven? Apk unknown

Question

Cannot get Android to work with maven. What could be the problem (generated from maven quickstart archetype):

Answer 1

Add extensions option to your android-maven-plugin configuration.

extensions

Whether to load Maven extensions (such as packaging and type handlers) from this plugin.

Sample configuration:

<plugin>
    <groupId>com.jayway.maven.plugins.android.generation2</groupId>
    <artifactId>android-maven-plugin</artifactId>
    <version>3.9.0-rc.2</version>
    <extensions>true</extensions>
    <configuration>
        <sdk>
            <platform>${android.platform}</platform>
        </sdk>
    </configuration>
</plugin>

This solves probem with apk unknown packaging.

Answer 2

I had same problem because I had android plugin added in <build><pluginManagement> section of configuration.

Moving it to <build><plugins> solved my issue.

Answer 3

I am currently using android-maven-plugin 3.1.1 for my project and give it a try with 3.2.0, It looks like Maven has some trouble downloading one of the required dependencies emma-2.1.5320.jar from Maven Central Repository, however, I have tired mvn clean install several times and finally get emma-2.1.5320.jar downloaded.

Try running mvn clean install several times, if it still doesn't work, download and install it manually, emma-2.1.5320.jar with source and javadoc are available on Maven Central Repository:

mvn install:install-file -Dfile=emma-2.1.5320.jar \
                     -Dsources=emma-2.1.5320-sources.jar \
                     -Djavadoc=emma-2.1.5320-javadoc.jar \
                     -DgroupId=emma \
                     -DartifactId=emma \
                     -Dversion=2.1.5320 \
                     -Dpackaging=jar

You should be able to use android-maven-plugin 3.2.0 now, hope this helps.

Answer 4

Replace the <version>3.2.0</version> with <version>3.6.0</version> and then clean and then install the package. 3.6.0 is the latest version of android-maven-plugin.

Answer 5

You have installed the "normal" Maven plugin that works for Java projects (and .jar files). For Android you need the Maven Android Plugin
