The error causes auto-completion to stop working, and a popup to occur containing this error message: “Compilation unit is not on the build path”. In this post I will share my solution to this problem.

Most of the projects I’m working on are controlled by a Subversion repository. They are also using Maven for dependency management. I searched a bit around the web and didn’t really find that many solutions for this problem. The first thing I found out was that I needed to create a new local Java Project when checking out the project from svn. So this is basically how you should checkout your projects from SVN in eclipse or SpringSource STS to avoid this problem.

File < Import < SVN – Checkout Projects From SVN < Choose your repository < Select the folder/trunk you want to checkout < The crucial point, select the “…New Project Wizard” and Finish < Now select Java and Java Project < Finish.

You should now have a local Java project containing the selected svn folder. You can now add Maven Dependency Management and Spring Project Nature to your project. Try opening a .java file and press ctrl-space. The error message should now be gone and auto-completion should be working.

It’s now possible with a Python syntax highlighter, called Pygmentize.

Pygmentize is a syntax highlighter written in Python. It can be used as a simple command line tool, as well as being reached from Python scripts.

In the following example I want to highlight a JavaScript file. I tell pygmentize to output HTML:

pygmentize -f html -o example.html example.js

The command above generated this output (I simply imported the HTML created by Pygmentize into my blog post).

if (time < 10)
{
    document.write("<b>Good morning</b>");
}
else
{
    document.write("<b>Good day</b>");
}


Take a closer look in the quickstart guide for more details on the command line tool, and how to use it in Python scripts. A package called Minted that utilizes pygmentize can be used to list source code in LaTeX. I used it in my Master thesis, and it looks so much better than the default lstlistings.

Read more about the application here. You can also take a closer look in iTunes via this link.

The book is titled “Beginning iPhone Development: Exploring the iPhone SDK“. The book is written by Dave Mark and Jeff LaMarche. Both have alot experience with Cocoa and Objective-C, so I think this is a good book. I gave the university library a visit too where I found a Objective-C book,  so no I’m well prepared for creating the next killer app!
