Using the Gradle build tool

During our development, we will need to build different build variants or run tests. Those tests can be executed for only certain build variants, if needed, or for all of them.

In the following examples, we will cover some of the most common Gradle use cases. We will start with cleaning and building.

As you remember, the Journaler application has the following build types defined:

• debug

./gradlew assemble.

This assembles everything--all the build variants that we have in our application. Imagine the time impact it can have if we are dealing with a really big project. Therefore, we will isolate the build command. To build only the debug...
