+Description: Robolectric is a unit test framework for Android.
+Local Modifications:
+- Removed Robolectric's dependence on Maven jars.
+- Switched Robolectric's XML parsing logic from using the vtd-xml library to
+  using the org.w3c.dom package.
+- Hardcoded version number in robolectric-version.properties.
+- Hardcoded ShadowProvider service config file. This file is normally generated
+  at compile time but it is difficult to use the generated file with GN.
