I am trying to build my Android project with Maven so I could automate my tests, but I’m getting the following error:

I can’t figure out what the error is!

Thanks a lot everybody in advance!

Answer 1

OK I got it: it was a configuration problem with the pom.xml:

<plugin>
        <groupId>com.jayway.maven.plugins.android.generation2</groupId>
        ...................
        <configuration>
            <sdk>
                <platform>17</platform>
            </sdk>
       </configuration>
 ............

Just make sure you choose the right SDK version there.
The value match_parent is not valid value for earlier versions than Android SDK 1.6 (I was having a <platform>4</platform>).
