Maven Compilation Error package R does not exists

Question

I am getting package R does not exist on building pom.xml file.

Compilation Error is:

Did you also try http://stackoverflow.com/questions/19496939/maven-compilation-error-for-android-project-error-package-r-does-not-exist and http://stackoverflow.com/questions/13128169/r-java-will-not-be-generated-android-maven-plugin? It looks like that is a generated class — andyb, Jan 10 '14 at 11:28
It looks like that file is generated by a Maven Android plugin but the Maven compile phase is not seeing the generated file since it is in a non-standard Maven source directory location - see http://stackoverflow.com/questions/12771526/unable-to-build-android-project-with-maven-android-maven-plugin — andyb, Jan 10 '14 at 11:37
yes the file is generated by Maven Android plugin, I have checked the link provided by you but the answers given their seems not working in my case. — Amrit Pal Singh, Jan 10 '14 at 11:47
Try adding the `build` directory where the `R.class` exists as a resource in `pom.xml` - see http://stackoverflow.com/a/19974322/637889 — andyb, Jan 10 '14 at 13:04

You have added com.jayway.maven.plugins.android.generation2 plugin,

Adding packaging to apklib, like this:

<version>0.0.1-SNAPSHOT</version>
<packaging>apklib</packaging>

That's ok
