Reasons for IntelliJ
I had been a long time Eclipse (7+ years) user before I made the jump to IntelliJ. Before Eclipse, I worked with Rational Application Developer, WSAD, JBuilder and Visual Age for Java. Compared to these IDE's, Eclipse was a joy to use. I could, for example, generate getters and setters, which was not possible in one of the older IDE's (we are talking about more than 10 years ago). Although I quite liked Eclipse I always thought there were some deficiencies. Mainly in the following areas:
- Why was there no core functionality bundled with the standalone Eclipse variant? For example Subversion and Maven integration.
- Why was it always painful to setup an Eclipse version to your liking with all the required plugins? With every new version I spent always nearly half a day setting up my IDE. This is unacceptable I think. The more plugins and functionality the harder it got.
- Updating to a new version was sometimes painful. Plugins that stopped working for example.
- I never quite liked the concept of a workspace. I already organize my projects on disk so I do not need a workspace concept.
- I did not like the idea of different perspectives. Why do I have to think about the context I am working in? For example: working with Java and Flex in one project. When I am in the Flex perspective my Java code completion/refactoring did work in Java files. Context should be file or even fragment driven.
- The editor itself. I invest heavily in knowing all the shortcuts. By knowing all the shortcuts I can code very fast. The instant code completion (not having to hit Ctlr-space all the time) is a joy to work with. Just type a couple of characters and hit Tab to complete the code. When I generate code, the cursor almost always is in the correct position to begin typing again. No need to touch the mouse or whatever.
- Code inspections and analysis tooling build in. I find it important to keep my code clean and bug free. The build in inspections and the ability to auto solve them are a really nice addition. Besides this you also have a dependency matrix viewer to get a quick overview of the dependency structure of your application and a duplicate code checker.
- Live templates. Live templates greatly increase coding speed. To make the most of it, I highly recommend creating your own templates. This is very easy. Just select a piece of code and select Save as Live template from the Tools menu. Press Ctrl/Cmd+J to view the live templates.
- Maven/Gradle integration out of the box. Just import a Maven project and Intellij knows the modules, dependencies etc. You can easily generate a dependency diagram from the Maven pom file to view all the dependencies at a glance. See figure 1 for an example of the Maven dependency viewer.
- Some handy tools. I often use the database editor and the RESTful web service test utility. The database editor has code completion in SQL and table creation. With the RESTful web service tester you can easily test HTTP services. The response can then me immediately saved and formatted as JSON or XML.
- Powerful refactorings and structural search & replace. IntelliJ knows a lot about my code. For example in Android: when I rename an image in the values/hdpi folder, it also renames the corresponding images in the mdi and xhdpi folder but also updates my XML views and code references to that image.
- Tasks and Contexts. I use IntelliJ in combination with YouTrack (there are more issue trackers that IntelliJ can integrate with). It is really easy to start working on an issue. IntelliJ creates a new context that tracks the files that belongs to that specific issue. I can mark the issue in progress and when I commit my changes it takes the comments from the context and uses this as the commit comments. It also changes the status of the issue to resolved when done working on the issue. All from within the IDE itself, no need for context switching.

- Stacked clipboard. You can have multiple entries in your clipboard. Just hit Ctrl-Shift-V to show the clipboard stack.
- Column mode in the editor. This comes in handy when working with fixed structure files like CSV for example.
- Darcula theme. This is one of the best dark themes I encountered. A dark theme is especially useful when coding in the evening with the lights dimmed. It is less stressful for the eyes I think. See figure 2 for an example of the Darcula theme.
- Stack trace analyzer. Just copy a stack trace from the clipboard and IntelliJ analyses it and matches it with the code to easily navigate to the problem at hand.
- Unit test and coverage integration.
- And many more.

Final thoughtsThis article describes the reasons why I use IntelliJ as my primary development tool of choice. Please note that this is my personal opinion. Also, this is obviously not an exhausted list. I would like to hear from you why you choose IntelliJ.
