Run Android test with Robolectric - dependency error

Question

I am using Android Studio 1.2 and Windows 7

When running a robolectric test following this example:

@RunWith(CustomRobolectricRunner.class)
@Config(emulateSdk = 21, reportSdk = 21, constants = BuildConfig.class)
public class PasswordProviderTest{

    @Test
    public void testGetPassword() throws Exception {
        Activity activity = Robolectric.setupActivity(LoginActivity.class);
    }

    @Test
    public void testSetPassword() throws Exception {

    }
}

test result or more the error stacktrace:

    Unable to resolve artifact: Unable to get dependency information: Unable to read the metadata file for artifact 'org.robolectric:android-all:jar': Cannot find parent: org.sonatype.oss:oss-parent for project: org.robolectric:android-all:jar:5.0.0_r2-robolectric-1 for project org.robolectric:android-all:jar:5.0.0_r2-robolectric-1

testCompile "org.robolectric:robolectric:3.0-rc2"

I find out that the resource, robolectric try to get ,is not avaible. When following the url it trys to get it: https://oss.sonatype.org/content/groups/public/org/sonatype/oss/oss-parent/

there is no oss 7. Why does robolectrics try to get a resource that is not there? And how to get it to work?

This seems to be a proxy problem. When behind proxy you have to specify proxy settings for maven at {userHome}/.m2/settings.xml

my settings.xml looks now like:

<settings>
    <proxies>
        <proxy>
            <active>true</active>
            <host>proxy.host</host>
            <port>3128</port>
        </proxy>
    </proxies>
</settings>

below not working !!

<settings>
    <proxies>
        <proxy>
            <id>proxy-https</id>
            <active>true</active>
            <protocol>https</protocol>
            <host>proxy.host</host>
            <port>3128</port>
        </proxy>
        <proxy>
            <id>proxy-http</id>
            <active>true</active>
            <protocol>http</protocol>
            <host>proxy.host</host>
            <port>3128</port>
        </proxy>
    </proxies>
</settings>
