Android with maven and Unresolveable build extension: Plugin com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.9.0-rc.3

Question

I am creating a POM file for an Android Project on Maven in Eclipse IDE. I also modified my proxy settings in the settings.xml file. I am getting two errors on the command prompt: 1)

Project build error: Unresolveable build extension: Plugin 
 com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.9.0-rc.3 or one of its dependencies 
 could not be resolved: The following artifacts could not be resolved: 
 com.jayway.maven.plugins.android.generation2:android-maven-plugin:jar:3.9.0-rc.3,

 com.jayway.maven.plugins.android.generation2:android-maven-plugin:jar:3.9.0-rc.3 from/to central (http://
 repo1.maven.org/maven2): No response received after 60000

and 2)

Project build error: Unknown packaging: apk

For the second error, I tried out the tips on Android with maven? Apk unknown, but of no avail. This is my pom file:

I would really appreciate suggestions and comments. Also, I am using the following version of maven and java:

Run Command

mvn eclipse:eclipse

make sure eclipse can see the libs. this meant going to the projectsetup/buildpath/libraries editor in eclipse and adding the variable M2_REPO to point to your local maven repository (e.g. something like /home/nacho3d/.m2/repository)

Your error, actually, looks to me like maven can't find a dependency for android-maven-plugin.

If it not works, then you need to set proxy: Configuring a proxy

Setting.xml file location

There are two locations where a settings.xml file may live:

The Maven install: $M2_HOME/conf/settings.xml

A user's install: ${user.home}/.m2/settings.xml

Then configure proxy from here http://maven.apache.org/guides/mini/guide-proxies.html – SkyWalker Jun 16 '16 at 06:00
Where can I find settings.xml file ? – Christopher Marlowe Jun 16 '16 at 06:03
What is the value of $M2_HOME ? – Christopher Marlowe Jun 16 '16 at 06:15
@SagorAhmed That is maven home folder. In windows it looks like `C:\apache-maven-3.3.9\conf` – SkyWalker Jun 16 '16 at 06:25

add this line of code in your pom.xml and try to rebuild your project.

this PluginManagement Might help you out.

<pluginManagement>
  <plugins>
    <plugin>
      <groupId>com.jayway.maven.plugins.android.generation2</groupId>
      <artifactId>android-maven-plugin</artifactId>
      <version>3.9.0-rc.2</version>
      <extensions>true</extensions>
    </plugin>
  </plugins>
</pluginManagement>

as well as you should add this dependency into your Project.

<dependency>
    <groupid>com.google.android</groupId>
    <artifactid>android</artifactId>
    <version>4.0.1.2</version>
    <scope>provided</scope>
</dependency>

then use the command

mvn eclipse:eclipse // to reset all .classpath files

and

mvn clean

Not sure but might resolve your problem I hope.

After your editing my xml file looks like this : http://paste.ofcode.org/r9AQZEKg8KnjgRE7GVsvD9 . But same error exists . — Christopher Marlowe, Jun 16 '16 at 05:59
