About RapidClipse

RapidClipse is a free Eclipse distribution for rapid cross-platform development with Java. RapidClipse is Eclipse - but preconfigured, extended with additional tools and optimized in many places to simplify professional application development with Java and Eclipse.


Visual and rapid - The terms visual and rapid in the explanation of RapidClipse are meant to express that application development with RapidClipse is easier and more comfortable than with the standard Eclipse installation. However, to infer from this that the possibilities with RapidClipse or the size of the solutions developed with it must be severely limited is completely wrong. RapidClipse is a preconfigured Eclipse installation enhanced with additional plug-ins and frameworks and thus has all the features and capabilities of the standard Eclipse installation. The tools and APIs included in RapidClipse are simplifications that you can use, but do not necessarily have to use. Features that are not suitable for your use case can always be replaced by other Java APIs or your own implementations. Switching from RapidClipse to Eclipse is therefore not a switch, but only a renunciation of tools that RapidClipse provides. * Unexpected complexity - RapidClipse greatly simplifies getting started with Eclipse and application development with Java - but don’t forget - RapidClipse is Eclipse. Due to the large number of Eclipse plugins, tools and APIs used in RapidClipse as well as the powerful Eclipse IDE itself, there are numerous setting and configuration options. This can also lead to problems in practice. Most of the time, these problems are not caused by RapidClipse bugs, but by incorrect settings, which can easily be fixed with some Eclipse experience. If you encounter such problems, please seek help in our free community forum or contact our RapidClipse support team. In our training courses you will get to know Eclipse very quickly, so that you can recognize the most common configuration problems right away and solve them yourself. * Moving from RapidClipse to Eclipse - You don’t have to think about whether a later move to Eclipse is possible. RapidClipse is Eclipse. Once you stop using RapidClipse’s tools, there is no difference. Code generated by RapidClipse behaves exactly like code written by hand, so you can continue to use it without RapidClipse tooling. Only the dependencies on the RapidClipse Open Source Framework remain, as with any other Java framework.

All important plugins and frameworks already preinstalled

In RapidClipse, all important Eclipse plug-ins needed for professional application development with Java are already pre-installed, pre-configured, and coordinated. The usual setup and configuration effort for Eclipse is completely eliminated with RapidClipse.

Additional Tools & APIs

The Eclipse plugins and frameworks used in RapidClipse are not only integrated, but optimized if necessary and extended with new tools and APIs developed specifically for RapidClipse to make their use easier and more comfortable for you. An example of this is the greatly improved Hibernate import of the JBoss Hibernate tools in RapidClipse.


RapidClipse projects are based on Maven. At project start, Maven automatically downloads all Java libraries (JARs) required for the project start as well as subsequently included Java libraries (JARs) from the central Maven repository (Maven-Central), automatically adds all dependencies to the pom.xml configuration file provided for this purpose, so that you do not have to deal with this anymore.

HTML 5 surfaces

RapidClipse applications are always Java web applications that feature a modern HTML5 interface.

RapidClipse Framework

With the RapidClipse Framework, RapidClipse also provides a databinding between Vaadin and Hibernate as well as a complete architecture and many important application infrastructure services that almost every modern business application needs. The application developer is freed from complicated low-level programming and can focus on business logic and user interface design.

Cross-Platform Development

With the RapidClipse deployment tools, any project can be deployed as a web application.
