QVT Operational – Manual Installation

You can safely skip this guide if the last step, QVT Configuration, worked without errors, and you can run transformations.

In some Eclipse installations, QVT Operational (QVTo) may not be available by default.

If you do not see:

Run As → QVT Operational Transformation

or QVT-related options in Eclipse, you will need to install QVTo manually.

Option 1 – Eclipse Marketplace

You can try installing QVTo via the Eclipse Marketplace:

Go to:

Help → Eclipse Marketplace

Marketplace search

Search for:

QVT Operational

Click Install and follow the steps.

In newer Eclipse versions, QVTo may not appear in Marketplace.
If it does not show, use the manual installation method below.

This method installs QVTo directly from the Eclipse update site.
You do not need to download the .zip file manually.

Step 1 – Open Install New Software

Open Eclipse.

Go to:

Help → Install New Software...

Install help

Step 2 – Add the QVTo Update Site

Click Add...

In the Add Repository window, enter:

Name: QVTo 3.11.2 Release Latest
Location: https://download.eclipse.org/mmt/qvto/builds/release/latest/

Add repository

Click Add.

Step 3 – Select Components

After Eclipse loads the available software, select:

  • QVT Operational
  • QVT Operational (tests)

Select components

Click:

Next

Step 4 – Review Install Details

Review the items to be installed.

You should see QVT Operational components such as:

  • QVT Operational Development Tools

  • QVT Operational SDK

  • QVT Operational Tests

Install details

Click:

Next

Step 5 – Accept the Licence

Select:

I accept the terms of the license agreement

Accept licence

Click:

Finish

Step 6 – Restart Eclipse

After installation, Eclipse will ask you to restart.

Click:

Restart Now

Verification

After restarting Eclipse, verify that QVTo was installed correctly:

  • Right-click a .qvto file
  • Select:
Run As → QVT Operational Transformation

If this option appears, QVTo is installed successfully.

Alternative – Install from Downloaded Archive

If the direct update-site method does not work, you can still install QVTo from the archive manually.

Go to the official release page:

https://download.eclipse.org/mmt/qvto/builds/release/latest/index.html

Download the .zip file, for example:

QVTo-Updates-3.11.2.zip

Then in Eclipse:

Help → Install New Software... → Add... → Archive...

Select the downloaded .zip file and continue with the same steps:

Next → Next → Accept License → Finish

Notes

  • Final tested version: QVTo 3.11.2

  • QVTo is still actively maintained, so newer versions may exist

  • Some Eclipse distributions already include QVTo

  • Use the direct update-site method first

  • Use the archive method only if the update-site method fails
