24 Performance

25 Goal Minimize the build time while using as little memory as needed.

26 Observation Typically, not much changes in the build between consecutive invocations of the build. When little changes in the build, little work should be done by the build.

27 Approach Performance enhancements are achieved through evolutionary improvements and revolutionary changes.

28 Apply To Fix hotspots Build configuration Cache and reuse Dependency resolution Work in parallel Task Execution Work in background

29 Daemon

30 ~/.gradle/gradle.properties org.gradle.daemon=true GRADLE_OPTS -Dorg.gradle.daemon=true Command Line gradlew tasks --daemon (--no-daemon)

31 Incremental build

32 Do not execute a given task if both its input and its output have not changed since the previous run. Inputs > Task > Outputs Optimize file change detection using file size, modification time, and content hash.

33 Continuous Mode

34 ./gradlew build -t

35 Project Substitution

36 configurations.all { resolutionstrategy.dependencysubstitution { substitute module("org.utils:api") with project(":api") substitute project(":impl") with module("org.utils:impl:1.3") } }

37 Android Studio 2.0

38 Android Studio post GP GP alpha1 Near Future Command Line gradle installdebug, 1 LOC added, Gradle Dexing Install Other Overall Estimate for Cold Swap & Emulator 2 Install

39 Gradle performance 9 Near Future Gradle 2.1 Near Future Gradle 2.9 Command Line gradle assembledebug, 1 LOC changed, Gradle Dexing Install Other Overall Without Improvements 30% slower

40 New Configuration Model

41 Goal Apply the concepts already available in the Execution phase to the Configuration phase. Describe what the model should look like and Gradle will provide the implementation.

42 Managed interface Picture { String getname() void setname(string name) List<String> gettags() }

43 Plugin class PicturesPlugin extends RuleSource void createpicture(picture picture) void configurepicture(picture picture) { picture.name = 'mypic.jpg' picture.tags.addall(['nature', 'night']) } }

44 DSL model { picture(picture) { name = 'mypic.jpg' tags.addall(['night', 'moon']) } }
