Remove support for Java 8, update dependencies, improve CI & ReadMe

* Java 8: The TravisCI build is failing due to trying to run the build in MacOS with Java 8 (not supported) * Dependencies: Updated the Junit to 5.3.2 and Gradle to 5.1.1 * CI: Modify the Bitbucket Pipeline in order to use Java 11 and split the `build` task into the `assemble` and `check` ones in order to be able to isolate which one could be failing * ReadMe: Add how to update dependencies section in order to make it easier for the end users in case of not having this repository updated to the latest versions

+This is a repository intended to serve as a starting point if you want to bootstrap a project in Java with JUnit and Gradle
 
 ## How To Start
 
-1. Install Java 8
-2. Clone this repository `git clone https://github.com/CodelyTV/java-bootstrap`.
-3. Run the tests with `./gradlew test`
+1. Install Java: `brew cask install java`
+2. Clone this repository: `git clone https://github.com/CodelyTV/java-bootstrap`.
+3. Execute some [Gradle lifecycle tasks](https://docs.gradle.org/current/userguide/java_plugin.html#lifecycle_tasks) in order to check everything is OK:
+ 1. Create [the project JAR](https://docs.gradle.org/current/userguide/java_plugin.html#sec:jar) and other project artifacts:
+ `./gradlew assemble --warning-mode all`
+ 2. Run the tests and plugins verification tasks:
+ `./gradlew check --warning-mode all`
 4. Start developing!
+
+## How to update dependencies
+
+* Gradle (current version: 5.1.1 - [releases](https://gradle.org/releases/)):
+`./gradlew wrapper --gradle-version=5.1.1 --distribution-type=bin` or modifying the [gradle-wrapper.properties](gradle/wrapper/gradle-wrapper.properties#L3)
+* JUnit (current version: 5.3.2 - [releases](https://junit.org/junit5/docs/snapshot/release-notes/index.html)):
+[`build.gradle:11`](build.gradle#L11-L12)
