Eclipse IDE
Eclipse and Intellij use different default layouts of Java imports. If used on the same project, Eclipse’s “Organize Imports” will compete with Intellij’s “Optimize Imports“.
To avoid distracting back-and-forth code changes, Intellij can be configured to match the default Eclipse behavior:
Go to File – Settings – Editor – Code Style – Java – Imports tab
Prevent on-demand imports (i.e. wildcards) by settings high count limits:
Define the imports layout (i.e. grouping and order) like this:
I used Cygwin’s unzip on Windows 7 to unpack freshly downloaded Eclipse zip packages. When trying to start eclipse.exe, I was getting weird error messages:
For Luna (4.4):
For Mars (4.5):
It turned out that after unzipping, the executable permission was not set on ‘exe’ and ‘dll’ files, so I had to fix it like this:
find eclipse \( -name '*.dll' -or -name '*.exe' \) -exec chmod +x {} \;

I currently have to work on an application using JRuby on Rails 3.2. My background is 12+ years of Java centric web development using Eclipse or IntelliJ.
There are a few things that I love about working with Java in Eclipse or IntelliJ that I miss when working with Rails:
Dynamic language fans might cringe at some of the points listed above. Feel free to provide constructive feedback or well-reasoned criticism.
There are however a couple of things that I like about Ruby on Rails 3.2:
I am still in the early phase of my Rails experience and I will try to post more about it as things evolve.
I am looking for something like this Java-CSS-Library, to implement server-generated CSS stylesheets backed by a type-safe object-oriented model of CSS classes and rule sets.
This is part of my ongoing quest for the perfect “pure Java” web development framework that would allow me to
Sonatype’s Maven integration for Eclipse (m2e) has been migrated to eclipse.org and is now available from the default update site for Indigo.
This means that you no longer have to add any Sonatype update sites as mentioned on the old (now outdated) m2eclipse site.
In particular, this also means that the old “m2e-extras” update site is obsolete for Eclipse 3.7.x and later. Things like WTP integration or Subclipse integration are now available as “m2e connectors” through Window – Preferences – Maven – Discovery.
All of this is very poorly (or not at all) documented on the new m2e home page and some people had problems with these changes.
Update 14/Aug/2018: I no longer maintain the package mentioned and the download links below are most likely broken.
I uploaded a lightweight Eclipse package (based on Helios 3.6.1) for web development (includes Maven, SVN and basic Spring integration, JEE / web tools plugins, but no Mylyn or other non-essential stuff) … This is currently only for Windows. It requires a JDK and is completely free / open source software.
