Installation Instructions

Development Environment

Install using Oomph Installer

The project provides a configuration file for the Eclipse Installer which eases the creation of reproducible development environments.

  1. Download the Eclipse Installer from https://www.eclipse.org/downloads/packages/installer.

  2. Clone our GitHub repository from the URL below.

  3. Open Eclipse Installer and switch to Advanced mode:

    switch to advanced mode

  4. In the product list, select "Eclipse Modeling Tools" with Product Version: 2022-09.

  5. In the Projects window, to the right of the text box, click the "+" to the add the Sysml2 project as user project. In the dialog, choose Catalog: Github Projects and browse the file system to select the setup file from the local git repository.

    • e.g. file:/C:/git/sysml/SysML-v2-Pilot-Implementation/org.omg.sysml.installer/SysML2.setup

    • Note: If you have installed the SysML v2 Pilot Implementation previously, this may already be pre-selected.

  6. Select SysML2 in the Projects list:

    oomph projects

  7. On the next page, update the following variables, then press Next.

    • Git clone location rule: Select "Located in specific absolute folder location" and browse to the directory for the SysML git repository.

    • Root install folder: Change this if you wish the installation to be under a specific folder.

    • Workspace location rule: Change this if you wish to place the workspace at a specific location.

  8. On the Confirmation page, press Finish.

  9. (Optional) For PlantUML visualization, GraphViz is needed. Visit https://www.graphviz.org/download/ and download the appropriate package for your environment.

    • In the menu of Window > Preferences > PlantUML in Eclipse environment, you may set up the path to GraphViz executable if Eclipse cannot automatically find it. For detail, visit https://plantuml.com/en/eclipse

Manual installation

  1. Install Eclipse 2022-09 (4.25) and Xtext.

  2. Clone our GitHub repository from the URL below.

  3. Import projects from the repository into your Eclipse workspace. This should include at least the projects:

    • org.omg.sysml

    • org.omg.kerml.expressions.xtext

    • org.omg.kerml.expressions.xtext.ide

    • org.omg.kerml.expressions.xtext.ui

    • org.kerml.xtext

    • org.kerml.xtext.ide

    • org.kerml.xtext.ui

    • org.sysml.xtext

    • org.sysml.xtext.ide

    • org.sysml.xtext.ui


  • Gradle is used to build project org.omg.sysml.jupyter.

  • Maven is used to perform a coordinated build of all projects (including packaging the SysML Interactive JAR file that is used by org.omg.sysml.jupyter).

  • To build the repository, invoke mvn clean package from the base SysML-v2-Pilot-Implementation directory.

  • If you have M2Eclipse installed (with the Tycho Project Configurators connector), it can also launch a Maven build in Eclipse using the launch configuration in SysML-v2-Pilot-Implementation/launch.

Prototype SysML Implementation

Getting Started

  1. Find the file org.omg.kerml.expressions.xtext/src/org.omg.kerml.expressions.xtext/KerMLExpressions.xtext, right click on it, and select Run As > Generate Xtext Artifacts, to execute the Xtext generator. Repeat with org.omg.kerml.xtext/src/org.omg.kerml.xtext/KerML.xtext and org.omg.sysml.xtext/src/org.omg.sysml.xtext/SysML.xtext.

  2. Once the generation is complete, right click on project org.omg.sysml, and select Run As > Eclipse Application. This should launch a new runtime Eclipse instance.

  3. Add the SysML-v2-Pilot-Implementation Git repository (already cloned previously) to the runtime Eclipse instance.

  4. Turn off Project > Build Automatically.

  5. Import the projects kerml, sysml and sysml.library into the runtime Eclipse workspace. (See the following section if you wish to create additional projects.)

  6. Execute Project > Clean with the following settings:

    • Clean all projects: Not selected

    • sysml.library: Selected

    • Start a build immediately: Selected

    • Build only the selected projects: Selected

  7. Repeat Project > Clean as above for kerml and sysml.

    • Important: Be sure to first build only sysml.library before building kerml or sysml.

  8. Double clicking on any .kerml or .sysml file will open it in the generated Xtext KerML or SysML editor.

  9. (Optional) To show SysML diagrams, in Window > Show View > Other…​ menu, you can enable PlantUML view.

Initializing New SysML Model Projects

  1. Open the New project wizard by selecting File > New > Project…​ menu item.

  2. Select General/Project.

  3. Give the project its expected name (and location if necessary), then press Next.

  4. On the Project References page, check the sysml.library project. This step tells Eclipse which other projects should be visible for resolving cross-references.

    project wizard

  5. Right-click the new project and select Configure > Convert to an Xtext project. This step sets up the indexing infrastructure necessary for resolving references between different files.

  6. Create any text files with .kerml or .sysml extensions to start working with a new file.

Note: Adding the project references to an existing project can be done in the project Properties dialog available from the popup menu on the project in the Project References page.

Note: If the Xtext setup (step 5) is missing, opening the KerML or SysML editor shows a dialog asking to convert the project to an Xtext project. Accepting this has the same results as manually selecting the menu item on the project.

For new code

Set up a Java code template as follows:

  1. Window > Preferences (Mac-OS: Eclipse > Preferences)

  2. Java > Code Style > Code Templates

  3. Code > New Java files > Edit

  4. Prepend (insert above the existing content) the following and modify the second line:

For existing code

  • When modifying existing code created by someone in a different organization, add a new copyright line, without changing anything else in the header.

  • When modifying existing code for the first time in a new year, add the year as the latest year in the appropriate copy right line. (E.g., in 2021, "Copyright © 2020" becomes "Copyright © 2020-2021" and in 2022 it becomes "Copyright © 2020-2022".)
