Error building Robolectric with GMS 7.8.0

[Christine]

I want to build Robolectric with version 7.8.0 (or 7.5.0) of Google Play Services. I updated the version number in two pom files, now when I run "install-dependencies.sh" I get

Installing com.google.androidgms:play-services from /opt/sdk//extras/google/m2repository/com/google/android/gms/play-services/7.8.0/play-services-7.8.0.aar
Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar
