Eclipse IDE project resources

Project information for Eclipse developers

Eclipse is an open source community whose projects are focused on providing an extensible development platform and application frameworks for building software. This article gives you links to the latest version of Eclipse, information on IBM's involvement with Eclipse, and a guide to some of the most interesting Eclipse IDE projects. Learn what Eclipse is good for, why it is important, how you can get started, and where to learn more about it.

What is Eclipse?

The short story is that Eclipse is an open source community focused on developing a universal platform of frameworks and exemplary tools that make it easy and cost-effective to build and deploy software.

There is a large consortium of major software vendors, solution providers, corporations, educational and research institutions, and individuals working cohesively to create an ecosystem that enhances and cultivates the Eclipse Platform with complementary products, capabilities, and services.

Eclipse provides value to three constituencies.

Users of Eclipse IDE-based offerings benefit from:

Java™ technology developers using Eclipse benefit from:

Developers of Eclipse IDE tools benefit from:

What is Eclipse good for?

This is a difficult question because the answer depends on the person inquiring. From the researcher's standpoint, Eclipse provides a platform to quickly prototype, collaborate, and share ideas built on a common architecture. From a tool developer's standpoint, you have access to a powerful and extensible platform, which makes it easy to develop higher-quality tools quickly and efficiently. If the whole platform is too heavyweight to use, Eclipse offers the Rich Client Platform (RCP), which is for applications that don't require a common resource model or some of the other features of the platform. The RCP FAQ is a great resource for understanding the capabilities of RCP. Look at the notable projects and popular applications listed in this FAQ to give you an idea of the capabilities of Eclipse IDE projects.

Why is Eclipse important?

The Eclipse IDE Platform builds confidence and trust by providing the source code for the platform. Software developers are tired of integrating tools and trying to deconstruct how to make tools work together in an environment. Making the Eclipse IDE Platform an open source initiative enables tool developers to do the same and to not only contribute new plug-ins but to also help improve the existing platform. In the end, the importance of Eclipse lies in the fact that everyone -- tool developers and users -- benefits from full disclosure on how to develop tooling at an industry level and, ultimately, benefits the end users.

What does IBM have to do with Eclipse IDE projects?

IBM® is the progenitor of the Eclipse Platform. The best way to explain IBM's involvement with Eclipse is to provide a short history of the three most important phases of Eclipse's climb to success:

The beginning
The platform began development by Object Technology International in 1998 (a subsidiary of IBM purchased in 1996, now known as the IBM Ottawa Lab) to address the problems raised by customers that dealt with the cohesiveness of IBM software tooling. Customers complained that IBM's tooling looked like it came from different companies and didn't work together. IBM took this to heart and listened.

The gift of open source
In 2001, IBM established the Eclipse consortium and gave the gift of Eclipse to the open source community. The goal was to let the open source community control the code and let the consortium deal with commercial relations. There were nine initial members of the consortium, which included IBM partners and competitors. IBM continued to nurture the evolution of the platform by funding various programs like Eclipse innovation grants and sponsoring Eclipse code camps.
The platform was developed using an open source model through an open source license where anyone is welcome to participate.

IBM wanted more serious commitment from vendors, but vendors perceived the Eclipse consortium as IBM-controlled and were reluctant to make a strategic commitment while IBM was in control. To resolve these problems, IBM relinquished any control. With the support of many companies, the Eclipse Foundation was formed in 2004 as a not-for-profit organization with a dedicated professional staff.

Today, IBM is committed to Eclipse IDE projects more than ever and takes an active part in the Eclipse Foundation as a strategic member. Furthermore, IBM has more developers contributing to Eclipse IDE projects than any other vendor.

What are the Eclipse communities?

Essential to the success of the Eclipse Platform are three intertwined communities:


  • An example group of committers is the Eclipse Web Tools Platform project team.

Plug-in developers

  • Eclipse Plugin Central contains a large sampling of plug-in developers.


Why should I contribute to Eclipse?

Eclipse is about many things, but one of those things is the Eclipse IDE ecosystem and the pursuit of profit. Eclipse IDE contributors are building products on top of extensible frameworks that provide value for everyone. The main reasons to contribute are:

There are other reasons that stretch into the development space, including better developer morale and increased product quality by participating in the community process.

How can I become an Eclipse IDE project committer?

The Eclipse Foundation created the Eclipse Development Process, which governs how Eclipse IDE projects are proposed and led. Eclipse is a meritocracy, which means that the more you contribute to Eclipse the more respect you will earn in the committer community. There are currently three ways to become an Eclipse IDE project committer (from easiest to hardest):

What should I know about using or contributing to Eclipse?

First, all of the content released by the Eclipse Foundation is governed under the Eclipse Public License (EPL). In May 2004, the EPL was approved by the Open Source Initiative (OSI) which makes the EPL an official open source license. The Eclipse Foundation provides several resources to help with licensing issues:

The Eclipse Foundation follows a development process based on open source methodologies. The process is called the Eclipse Development Process and dictates how all development should happen under the Eclipse umbrella. To better help people understand this process, there is a set of Eclipse Development Process Guidelines.
