Install Eclipse Plugins – The Easy Way

Eclipse as of today is the industry’s major non-Microsoft software

tool platform. The number of companies adopting this platform is a testimonial of the platform’s success.

(Check my previous post for more on the history of Eclipse IDE


Eclipse has a well-designed, and extensible architecture. What is valuable about Eclipse is that it provides an open source platform for creating an extensible integrated development environment. This platform allows anyone to build tools that integrate seamlessly with the environment and other tools.

The key to the seamless integration of tools with Eclipse is the plug-in. With the exception of a small run-time kernel, everything in Eclipse is a plug-in. This means that a plug-in you develop integrates with Eclipse in exactly the same way as other plug-ins.

Any new person who is introduced to Eclipse in concerned with one important question : How to Install Eclipse Plugins ?

There are lot of useful, high quality third party plugins

available and all the plugin installation instructions specify at most 2 ways to install Eclipse Plugins

Normal Ways of Installing Eclipse Plugin

I will take the Eclipse Webtools Plugin to describe the 2 “normal” ways of installing Eclipse Plugins. In the next section I will show how the same can be done in a “easy” way.

This is how the Eclipse SDK folder structure looks like:

After extracting the Webtools package you have this folder hierarchy:

One of the common method of installing is to copy the contents of the “features” into the “features” folder of eclipse, and do the same with the “plugins” folder.

The other way of installing, which Eclipse also recommends is via the Update Manager.

You can choose the components you wish to install, choose the dependent plugins etc. In this process, generally you select the default installation location specified by the wizard.

The advantage with this approach is that when you select a component you are also made aware of the dependent plugins that needs to be installed. For e.g. If I select Web Tools, I am also told to select/install GEF

The disadvantage with this approach is that it never works well in a low bandwidth environment. I have struggled so many times to install via update manager, somewhere its gets stuck and I am left with a partially installed, corrupted environment.

The Easy Way

Now for the “Easy” way of installing Eclipse Plugins. Very few people are aware of this concept and Eclipse somehow doesn’t seem to document this approach anywhere.

This method uses the concept of “Links”. Here is the step by step procedure. (In the explanation I have used the installation of Webtools as the example)

1. Create a folder named links inside the eclipse folder (See Picture below)

2. Create a new file inside this folder and name it as say Note that the file name can be any valid string, but the extension has to be link.

3. Assuming that I have copied the Web tools into D:\thirdparty as shown below,

the contents of has to be this:


Points to Note:

  • The string should always start with “path=” keyword.
  • The path should point to a directory which has a “eclipse” folder which in turn has “features” and “plugins” as sub-folders
  • It is recommended to use forward slash ‘/’ in the path (If you want use Backslash, see that you use the escape character i.e. in Windows it should be “\”)
  • The file extension should end with “link
  • The file (i.e in our example) should exist in the “links” folder.
  • It is recommended to create link files only for big plugins/applications. For small plugins you can create just one link file, say and copy all the small plugins to the path referred by this link.

Restart Eclipse and now all the plugins and feature descriptions should be read from the path referred by the “link” files.


Eclipse has a lot of top level and technology projects. To experiment with these projects, the “links” concept comes to the rescue. You can extract the plugin to a “thirdparty” (or a folder of your choice) and just link it within the eclipse installation. My current configuration looks like this:

Eclipse Projects/Third Party Plugins

Corresponding Link files

The “Copy” approach just bloats the eclipse installation and you cannot remove/uninstall the plugin easily. With links approach, you can just remove the “link” file and the plugin is uninstalled !!

The same links directory can be used in another eclipse installation. For e.g. if you are working with Milestone or different version of Eclipse, you can just copy the links folder (containing .link files) and the plugins are installed.

It is very easy to manage different versions of a plugin. If a new version doesn’t work, reverting back to a previous version is pretty easy.

Also, if you use the update feature in Eclipse, you can choose one of the above folders as the installation directory.


This approach seems to work fine in both windows and linux. I am not sure why this approach is not documented in Eclipse. I found out about this when I was using the trial version of RAD (Rational Application Developer). It was used primarily to manage product extensions. I believe the same concept can be used to manage plugins (Install/Uninstall).

Hope this post was useful, if you had any problems using this approach, do leave a comment with the problem description.
