How to run 'rebuild project' from the command line

Question

Some Context:

I am working on a Continuous Integration pipeline with MSBuild for a large project that includes an Android application. This application includes some automatically generated files that need to be integrated into the project regularly. This is usually accomplished by manually copying them over and selecting Build->rebuild project in android studio.

This step is necessary since the project also makes use of AndroidAnnotations, which generates classes at compile time.

The Problem:

I haven't found any documentation for what is run when you select 'rebuild project' in android studio.

What I Have Tried:

How to Rebuild and Run android project from command line

as well as:

What is happened after I run rebuild project in Android studio?

But the doccumentation here doesn't talk about the rebuild command, and a 6 week udacity course isn't a helpful resource either.

When I hit 'rebuild project' the Android Studio event log reads:

Executing tasks: [clean, :app:generateDevelopmentDebugSources, :app:generateDevelopmentDebugAndroidTestSources, :app:prepareDevelopmentDebugUnitTestDependencies, :app:mockableAndroidJar, :app:compileDevelopmentDebugSources, :app:compileDevelopmentDebugAndroidTestSources, :app:compileDevelopmentDebugUnitTestSources]

Which I have run in the command line as follows:

gradlew.bat clean :app:generateDevelopmentDebugSources :app:generateDevelopmentDebugAndroidTestSources :app:prepareDevelopmentDebugUnitTestDependencies :app:mockableAndroidJar :app:compileDevelopmentDebugSources :app:compileDevelopmentDebugAndroidTestSources :app:compileDevelopmentDebugUnitTestSources

The command executes, but the build finishes with several hundred errors, which also occur when you try to compile or clean without first running rebuild. Obviously this command is incomplete.

When I look at the Gradle Console in Android Studio I see a couple of dozen targets that are run, but I'm hesitant to copy-paste those, as I have no idea what small changes to the project will necessitate different targets to be run.

I've narrowed down my issue to the :app:compileDevelopmentDebugUnitTestJavaWithJavac target. This target requires one of the other targets listed in the Gradle Console, but I don't know which one.

Those targets have to be coming from somewhere, but where?

tl;dr:

How can I do all the things that Android Studio does when I run 'rebuild project' from the command line?

Answer 1

Rebuild and build are the same thing. You can list all the gradle tasks by running a command gradle task --list or gradle -q :tasks --all . There you can see different types of gradle tasks. For example, install tasks, build tasks, assemble tasks, publishing tasks, verification tasks, build setup tasks, clean tasks, android task, or your own custom named tasks etc. Run on the build tasks from your module (e.g., MyModule:build) like this gradle MyModule:build (or ./gradlew MyModule:build if you wanna use inside gradle wrapper)

Note: you can see your runnable/buildable module from Run Configurations also.

Answer 2

Please open build view in Android Studio, when you select from menu: Build -> Rebuild Project on the top in build view you will see which tasks were triggered by Android Studio: Executing tasks: [clean, :assembleDebug] in project ...

And now you can try to do this from command line:

./gradlew clean assembleRelease
