IntelliJ Idea offers only around 750 plugins whereas Eclipse provides 1250+ plugins with many plugins for new technologies. Apne tv hindi. When it comes to performance, Eclipse is much faster for large projects as compared to IntelliJ because of its technique of indexing the whole project at the initial stage. The first version of IntelliJ IDEA was released in January 2001, and was one of the first available Java IDEs with advanced code navigation and code refactoring capabilities integrated. In a 2010 InfoWorld report, IntelliJ received the highest test center score out of the four top Java programming tools: Eclipse, IntelliJ IDEA, NetBeans and JDeveloper.

Project Structure and Configuration. Project structure and configuration in IntelliJ IDEA is very different from Eclipse. Almost everything—from project structure, folder management, how the packages are represented in the project tree, and this terminology issue with projects vs modules—looks really weird to an experienced Eclipse user. I have been using Eclipse IDE for almost 8 years now, though I have used various flavours that is build over eclipse like IBM RAD, Netbeans and some PHP IDEs but recently moved to IntelliJ because many say its better for Android App Development. Also, Google released the Official Android Studio ver 1.0 that is based on IntelliJ this year.

Being a long time Eclipse user I recently started using IntelliJ. Here are some notes on how I use it for Java and Kotlin. I will probably update this post continuously.

Here are some of the topics that I thought were most interesting when doing the switch.

Free and Open Source

I don't want to depend on software that is not free and open source. That, to me, feels like a trap and something I want to avoid.

Eclipse is free and open source.

IntelliJ has a community edition that is also free and open source. This is the one I use.

This is totally fine for me. Less is more!

Synchronize Settings

I want to automatically have my IDE setup exactly how I want it and synchronize that to all my installations. Avoiding the time consuming task of searching for settings and clicking checkboxes.

Idea

In Eclipse I use Workspace Mechanics. The mechanics files are put under version control so that all developers of a project will have changes applied immediately when someone changes the settings.

In IntelliJ this is built in. In the menu, File -> Settings Repository you can add any git-repository. I just created a new repository on GitHub and is now using that clone URL. To publish settings you do File -> Settings Repository and click Merge.

I have seen that some settings are not synchronized when using IntelliJ. I really miss automatically download sources and documentation and most annoyingly is the option to optimize imports on the fly.

Opening Several Projects In Same Window

In Eclipse you would create a workspace and import projects in that workspace.

In IntelliJ you create a project and add modules to it. A module can be a Maven, or Gradle, project. You do:

  • File -> New -> Project ..
  • Empty project
  • Name it anything you like
  • Finnish
Download

Now to add a Gradle project to it, you do:

  • File -> New -> Module From Existing Sources..
  • Select the build.gradle file. If it were Maven you would select the pom.xml file

Maintaining a Code Standard

In Eclipse you can setup save actions that will apply the code standard whenever a file is saved.

In IntelliJ I have not found any way of enforcing a code standard. It does a good job on understanding and adhering to how the current file already is formatted.

I always use an external tool for coder formatting, if I can find one. So that developers can use any editor. But sometimes I am not the maintainer of the project or other developers don't agree with me about doing it that way.

Automatically Boost Code Quality

Difference Between Intellij And Eclipse

In Eclipse I would setup save actions to automatically do things like:

  • Remove unused variables
  • Organize imports, sorting and removing unused imports
  • Adding final keyword to immutable attributes and variables
  • Remove trailing white space

In IntelliJ you can find these settings by simply searching in the settings menu (File -> Settings).

This will organize the imports when you are working with a file. You can also batch this by marking a folder in the menu and press CTRL-ALT-O.

Intellij Idea Vs Eclipse

In Eclipse I let Eclipse compile the code whenever I change anything. I immedely get clear feedback if any code does not compile.

Eclipse Rcp Intellij Idea

I struggle with this in IntelliJ. It does not tell me about code that does not compile.

If I manually browse to a file that I know does not compile, and open it, IntelliJ will tell me it does not compile.

This is annoying as I keep getting compilation errors when building outside of IntelliJ which slows me down.

In Eclipse I can reveal whatever file I open in the project view to the right.

It can be done in Intellij also.

Eclipse does a really good job showing me projects and their parts. The project, source-folders, packages and files.

In IntelliJ I found flattern packages.

But it is not as clear as with Eclipse.

I am missing some features in IntelliJ regarding automatically correcting things in the code. But that is easily solved with Maven or Gradle. I wrote about that here.
