which is now pulled from mavenCentral.

-    Uses piasy/BigImageViewer which gets build and installed to a local maven repo in srclib prepare step.
-
-    In prebuild we do weird stuff for replacing `maven {` with `mavenLocal {`. tac reverses the lines so we can match the following repo url.
-    The awk call then matches the url, deletes the matching line and replaces the following line. No idea how it works, but it does.
-    Finally reverse the lines again and move back to original build.gradle file.
-
-    Upstream builds and publishes a libre build of the jitsi sdk. The maven repo can be recreated by using tools/jitsi/build_jitsi_libs.sh
-    We use that build instead of doing our own for now as jitsi embeds a timstamp in the version number and it's a major pain to maintain.
