+# Gradle
+
+Gradle is used to build OpenWhisk. It does not need to be pre-installed as it
installs itself using the [Gradle
Wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html). To use
it without installing, simply invoke the `gradlew` command at the root of the
repository. You can also install `gradle` via
[`apt`](http://linuxg.net/how-to-install-gradle-2-1-on-ubuntu-14-10-ubuntu-14-04-ubuntu-12-04-and-derivatives/)
on Ubuntu or [`brew`](http://www.brewformulas.org/Gradle) on Mac [...]
+
+## Usage
+
+In general, project level properties are set via
`-P{propertyName}={propertyValue}`. A task is called via `gradle {taskName}`
and a subproject task is called via `gradle :path:to:subproject:{taskName}`. To
run tasks in parallel, use the `--parallel` flag (**Note:** It's an incubating
feature and might break stuff).
+
+### Build
+
+To build all Docker images use `gradle distDocker` at the top level project,
to build a specific component use `gradle :core:controller:distDocker`.
+
+Project level options that can be used on `distDocker`:
+
+- `dockerImageName` (*required*): The name of the image to build (e.g.
whisk/controller)
+- `dockerHost` (*optional*): The docker host to run commands on, default
behaviour is docker's own `DOCKER_HOST` environment variable
+- `dockerRegistry` (*optional*): The registry to push to
+- `dockerImageTag` (*optional*, default 'latest'): The tag for the image
+- `dockerTimeout` (*optional*, default 240): Timeout for docker operations in
seconds
+- `dockerRetries` (*optional*, default 3): How many times to retry docker
operations
+- `dockerBinary` (*optional*, default `docker`): The binary to execute docker
commands
+
+### Test
+
+To run tests one uses the `test` task. OpenWhisk consolidates tests into a
single `tests` project. Hence the command to run all tests is `gradle
:tests:test`.
+
+It is possible to run specific tests using [Gradle
testfilters](https://docs.gradle.org/current/userguide/java_plugin.html#test_filtering).
For example `gradle :tests:test --tests
"your.package.name.TestClass.evenMethodName"`. Wildcard `*` may be used
anywhere.
+
+## Build your own `build.gradle`
+In Gradle, most of the tasks we use are default tasks provided by plugins in
Gradle. The [`scala`
Plugin](https://docs.gradle.org/current/userguide/scala_plugin.html) for
example includes tasks, that are needed to build Scala projects. Moreover,
Gradle is aware of *Applications*. The [`application`
Plugin](https://docs.gradle.org/current/userguide/application_plugin.html)
provides tasks that are required to distribute a self-contained application.
When `application` and `scala` are used [...]
+
+In OpenWhisk, we want to distribute our application via Docker images. Hence
we wrote a "plugin" that creates the task `distDocker`. That task will build an
image from the `Dockerfile` that is located next to the `build.gradle` it is
called from, for example Controller's `Dockerfile` and `build.gradle` are both
located at `core/controller`.
+
+If you want to create a new `build.gradle` for your component, simply put the
`Dockerfile` right next to it and include `docker.gradle` by using
+
+```
+ext.dockerImageName = 'openwwhisk/{IMAGENAME}'
+apply from: 'path/to/docker.gradle'
+```
+
+If your component needs to be build before you can build the image, make
`distDocker` depend on any task needed to run before it, for example:
+
+```
+distDocker.dependsOn ':common:scala:distDocker', 'distTar'
+```
