1108881 - Compile Fennec third party libraries as separate JARs

Status: NEW

(Firefox Build System :: Android Studio and Gradle Integration, defect)

Description

[Nick Alexander :nalexander [he/him]]

For convenience, we've dumped all our third party sources (except the Sync-only httpclient dependency) into a single thirdparty.jar.  Turns out that's a significant compile-time bottle neck.

This ticket tracks splitting that monolithic jar into individual jars and getting the compile pipeline more consistently full.  There's a dep between some early jar (mozglue? util?) that can be shaved from thirdparty.jar to just Apache commons, I think.

In order to do this properly, the Gradle configuration needs to be updated as well.  In order to make the Gradle/IntelliJ integration work, we need to expand the directory hierarchy (like in Bug 1107811).  (These tickets are similar but neither blocks the other.)  The standard Android layout dictates that we move

m/a/thirdparty/ch

into

m/a/thirdparty/httpandroidclientlib/src/main/java/ch.

We'll add the requisite new Gradle projects at the same time, so that we get the Gradle side compile time improvements.  (And free dex time improvements!)

I'd like to name the Gradle projects rather verbosely, at least at first, like thirdparty_ch_boye_httpandroiclientlib so that they sort together in IntelliJ.  Unfortunately, I don't think we can group them automatically (yet?).
