Eclipse Plug-in Development Beginner's Guide - Second Edition

By: Alex Blewitt

Overview of this book

Eclipse is used by everyone from indie devs to NASA engineers. Its popularity is underpinned by its impressive plug-in ecosystem, which allows it to be extended to meet the needs of whoever is using it. This book shows you how to take full advantage of the Eclipse IDE by building your own useful plug-ins from start to finish. Taking you through the complete process of plug-in development, from packaging to automated testing and deployment, this book is a direct route to quicker, cleaner Java development. It may be for beginners, but we're confident that you'll develop new skills quickly. Pretty soon you'll feel like an expert, in complete control of your IDE. Don't let Eclipse define you - extend it with the plug-ins you need today for smarter, happier, and more effective development.

Time for action – error markers if file is empty


Errors and warning markers are used to indicate if there are problems in the source files. These are used by the Eclipse compiler to indicate Java compile errors, but they are also used for non-Java errors. For example, text editors also show warnings when words are misspelled. A warning can be shown if the .minimark file is empty and the title is missing.

There isn't a simple way of accessing the file's size in Eclipse, so one heuristic is that if the generated HTML file is less than about 100 bytes then there probably wasn't much to start with anyway.

  1. Open the MinimarkVisitor class and go to the processResource method.

  2. When the HTML file is generated, put in a test to determine if the size is less than 100 bytes:

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    MinimarkTranslator.convert(new InputStreamReader(in),
     new OutputStreamWriter(baos));
    ByteArrayInputStream contents = new ByteArrayInputStream(
     baos.toByteArray());
    if (baos...
