By default on Windows Eclipse autocomplete shortcut is: Ctrl+Space. In my Mac laptop I use this combination for the operating system’s spotlight quick search. As a result, I wanted to change the default autocomplete shortcut. What you need to do is:

1. Go to Window->Preferences (Eclipse -> Preferences on Mac).

2. In the new window that pops up, go to “General -> Keys”

3. Find the “Content Assist” command and change it to whatever you like (in my case I chose Cmd+Space).

4. Don’t forget to click on “Save” on this pop up window!

From time to time I develop something on Eclipse. Apart from the usual Eclipse operations (build and test) that I do with the Eclipse Ant and JUnit plugins (they ship with Eclipse for Java), I also wanted to carry out some dependency analysis on existing code. Of course JDepend is the obvious option, but I found a nice article from IBM that suggests some additional plugins that help the coder carry out day to day tasks such as Complexity monitoring and Coding standard analysis.

The following is a summary of the plugins proposed by the article. Of course all of them are opensource/free.

I recently installed eclipse 3.3 and Java 1.6. Today I tried to use SiTra (Simple Transformations in Java) but when I tried to compile it Java started complaining on the following methods of the SimpleTransformerImpl.java:

The error was something about java inconvertible types. I don’t know if it is the new version of eclipse or Java 1.6. Looks like for some reason the compiler doesn’t recognise that Rule.class is of type Class<? extends Rule<S, T>>, so as to call the public <S, T> T transform(Class<? extends Rule<S, T>> ruleType, S source)

A simple solution is to ct the Rule.class expression to Class (it sounds weird but it worked).

So the transform and transformAll methods become:
