Download

Download the Eclipse Installer and select Epsilon. Note that you will need a Java Runtime Environment installed on your system.

Windows macOS Linux

Advanced Mode: If you don't see Epsilon in the list, click on the three vertical bars on the top right, then Product Catalogs and check "Eclipse.org Applications". Epsilon should be near the bottom of the list (you can also use the search bar). If the Product Catalogs option is missing, switch to Advanced Mode and look for Epsilon under "Eclipse.org Applications" (if this category is missing, click on the small yellow folder icon in the top right corner and select it). Keep pressing Next (you don't need to change anything) and then Finish. Accept the licenses when prompted.

Important: Please do not select the Epsilon project on the second page of the installer in Advanced Mode. This is for Epsilon developers only and may cause issues during installation of the Epsilon product.

Note for Windows users: Please make sure that you install Eclipse close to the root of a drive (e.g. C:\Users\<username>\Epsilon) as the maximum path length on Windows may not exceed 255 characters by default.

Stable


Uncheck the "Show only the latest versions of available software" check box in Eclipse's new software installation dialog and select version 1.3.

Prerequisites

The development tools of Epsilon come as a set of Eclipse plugins and therefore, to install Epsilon you need to download and install a Java Runtime Environment and Eclipse first. The Eclipse Mars Modeling Tools distribution contains most of the necessary prerequisites for Epsilon 1.3 and is available for the following platforms.

Windows macOS Linux

Dependencies (optional)

Below are optional dependencies that are not pre-installed in the Eclipse Mars Modeling Tools distribution.

DependencyUpdate siteNotes
Emfatic Untick the " Group items by category " check box
GMF

EpsilonLabs (optional)

Some of the projects found in the EpsilonLabs repository can be installed from the EpsilonLabs update site.

EpsilonLabs

The source code of Epsilon is stored in the following Git repository.

Release tag

Additional projects which are experimental or not formally approved due to licensing constraints are available in Epsilon Labs.

Since 1.4, these JARs are also available from Maven Central. For instance, to use the epsilon-core JAR from your pom.xml:

<dependencies>
  ...
  <dependency>
    <groupId>org.eclipse.epsilon</groupId>
    <artifactId>epsilon-core</artifactId>
    <version>1.5.1</version>
  </dependency>
  ...
</dependencies>

You can use the latest SNAPSHOTs at the Sonatype OSSRH repository. For instance, to use the 2.1 interim epsilon-core JAR from your pom.xml:

<repositories>
    <repository>
      <id>ossrh-snapshots</id>
      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
    </repository>
</repositories>
...
<dependencies>
  <dependency>

    <artifactId>epsilon-core</artifactId>
    <version>2.1.0-SNAPSHOT</version>
  </dependency>
</dependencies>

Ready-to-use Eclipse Mars (4.5) distributions containing a stable version of Epsilon (v1.3) and all its mandatory and optional dependencies. You will only need a Java Runtime Environment.

Windows macOS Linux

Note for Windows users: Please make sure that you extract the downloaded distributions close to the root of a drive (e.g. C:) as the maximum path length on Windows may not exceed 255 characters by default.



Version 1.3 fixes the bugs and implements the enhancement requests below.
