Overview

Most important for Java development is the JDK, the Java Development Kit.
Main tool for Java development is the IDE, for which I use Eclipse. Main reasons why I use this are:

• Support for EMF (Eclipse Modeling Framework)
• I have experience with it

JDK

The JDK can be downloaded from https://www.oracle.com/java/technologies/downloads/.
After installing a new JDK version make sure to update the following environment variables:

Eclipse

Main site eclipse.org.

Eclipse package and plug-ins

The Eclipse package to use is Eclipse Modeling Tools, which can be downloaded from https://www.eclipse.org/downloads/packages/.
After installation, add the following plug-ins:

m2e – Maven integration for Eclipse
When installing this from the MarketPlace (in version 2024-06) it says that it is not available. Just click continue anyway.

Other plug-ins

Checkstyle
A source code analyzer, to check on Coding Standards. Install from the Eclipse Marketplace.
To run Checkstyle on a file, right click on a class and select Checkstyle/Check Code with Checkstyle.
Currently 2 main problems in using it:

• White space at the end of a line
  The editor adds white space for indentation
• Order of imports
  Editor puts java imports first, Checkstyle expects fully alphabetical

Eclemma
Code Coverage. Link for installing in Eclipse: http://update.eclemma.org/ (or install from the Marketplace)

Soyatec – eUML2
UML support. See http://www.soyatec.com/euml2/

Android development in Eclipse

The answer is ‘don’t do it’.
There was a time when Eclipse was the most used IDE for Android development, but now adays the support isn’t good anymore. I tried it (februari 2024) and it failed.
Instead use Android Studio.
