Lab Setup

To build the applications in this workshop, you’ll need a couple of things:

• Git

• Java JDK 8

• Your favorite IDE or editor (e.g., Eclipse or Spring Tool Suite, IntelliJ IDEA, NetBeans, Visual Studio, etc)

We’ll be pushing applications and creating services in Pivotal Cloud Foundry (PCF). This workshop uses Pivotal Web Services, an instance of PCF hosted by Pivotal.

• Create a free Pivotal Web Services account.

• Click the Tools link and…​

  • download and install the CLI matching your operating system

  • login to the CF CLI (cf login -a api.sys.yorbalinda.cf-app.com --skip-ssl-validation)

IDE Setup and tips

💡	This section shares some optional tips for configuring your IDE for an optimal experience during the workshop!

Eclipse / Spring Tool Suite

Exclude java.awt.* from auto-complete suggestions

Preferences → Java → Appearance → Type Filters → Add…​ → java.awt.*

This way when you need to auto import something with List you don’t get the dialog box that asks if you want java.awt.List when you really want java.util.List

Configure Maven Auto Update

Preferences → Maven → [✔] Automatically update Maven projects configuration

Allows you to change a pom.xml and have the eclipse classpath automatically change without having to trigger the change manually.

Open pom.xml in XML view

Preferences → Maven → User Interface → [✔] Open XML Page in the POM editor by default

This will get you straight to the XML when you first open your pom.xml

Show line numbers

Preferences → General → Editors → Text Editors → Show Line Numbers

Very useful when collaborating and you need to explicitly state which line number you are referring to.

Automatically refresh resources changed outside of Eclipse

Preferences → General → Workspace → Refresh using native hooks or polling

This enables Eclipse to recognize changes to files that have been modified outside of Eclipse. Pretty handy.

Close all views you don’t need

Give yourself more space to view/write code by closing any views in the perspective that you don’t use, such as: Outline, Spring Explorer, and Servers

Boot Dashboard

Use it, it’s awesome :)
