Bug 1041395 and friends added Gradle and IDEA integration; Bug 1103121 added |mach gradle|. This ticket tracks adding an opt-in build mode that builds mobile/android with Gradle rather than with the usual moz.build/Makefile.in rules. That will include: * a configure.in flag (--enable-mobile-android-gradle-build or similar); * whatever config/ and tooltool magic is needed to get try builds standing; * invoking gradle from mobile/android/{base/?}Makefile.in as appropriate; * configuring Gradle to Proguard as appropriate; * arranging to export classes.dex to dist/, etc.

I forget that this will need to build robocop.apk as well.

jcenter() now contains both com.squareup.spoon:spoon-runner:1.1.10 and org.simpleframework:simple-http:6.0.1 so we can get rid of some outdated listings. Review commit: https://reviewboard.mozilla.org/r/30449/diff/#index_header See other reviews: https://reviewboard.mozilla.org/r/30449/

Opt-in by adding --enable-building-mobile-android-with-gradle. Configure the location of Gradle with --with-gradle. Gradle dependencies (including the Android-Gradle plugin) are fetched from the jcentral repository for local developers, and from the GRADLE_BUILDSCRIPT_MAVEN_REPOSITORY path in automation. Android-specific Maven dependencies are shipped as "extras" with the Android SDK, and should be found automatically by the Android-Gradle plugin.

This is a convenience, and a look ahead to a Gradle-based future. The reason to do this is that front-end builds don't (really) support testing, so we set --disable-tests. However, this means that mobile/android/tests/browser/robocop doesn't get processed at build time, and that means the Robocop manifest doesn't get preprocessed. Rather than hack generating the Robocop manifest in, let's skate to where the puck is going and just use Gradle where appropriate.

I have no particular attachment to anything here other than using a stripped down manifest that does not include the NDK toolchain. This is grade A cargo cult, with extra cult followers.

Folks -- these are somewhat experimental commits. sebastian, I think yours is no issue. gps, this is a sequence of hacks to try to opt-in a Gradle build mode before eventually just using Gradle across the board. It's not pretty but it keeps our current shape, which is basically needed for l10n repacks. That is, we need to produce a classes.dex and a fennec.ap_ independently, at any time, which is madness but there you have it. dustin, this is straight cargo. Feel free to set direction (I've been cribbing from the eslint ticket) or redirect as appropriate. I have additional tickets that build on this frontend build; I don't know how to structure them, so I'll just push them at you (tomorrow) and let you guide me.

gps: you reviewed this at https://reviewboard.mozilla.org/r/27237/. It got attached to the wrong ticket. I stripped some of the automation stuff (Gradle binary choice, repository stuff). I'll add that back for automation builds eventually; I want to get some local testers onto this and ferret out races, etc. I didn't rewrite the internal variable name (just the external --enable... flag) since the variable will go away eventually.

https://reviewboard.mozilla.org/r/30451/#review31117 > I'm surprised to see this change here. I grok that MOZCONFIG could be ''. I'm just curious how you managed to tickle this. I never figured out why. I tickled this two different ways, both of which involved running mach in strange environments. I see '' intermittently when invoking mach as part of a Gradle build, kicked off from within IntelliJ / Android Studio (under Mac OS X). I also saw it when invoking mach as part of a buck build. I tried quite hard to understand the buck environment and how it would differ, but found nothing -- it appeared to be a Java quirk. > That's the 2nd time I've seen this block. If there were 3, I'd insist on moving it to an included .mk file. But I'll allow it. This signing actually applies to both `moz.build` and Gradle, so I thought I might add some variable like `ANDROID_SIGNED_APKS` to collect these. We should be able to determine the output locations fairly automatically, and do the right thing at package time.

Hi, had to back this out since this caused problems with the merge from mozilla-inbound to mozilla-central like warning: conflicts while merging mobile/android/base/Makefile.in! (edit, then use 'hg resolve --mark') warning: conflicts while merging mobile/android/moz.build! (edit, then use 'hg resolve --mark')
