The MTA (Migration Toolkit Assistant) plug-in is published by Red Hat and available in the Eclipse Che plug-in registry.

We would like CodeReady Workspaces to offer the same plugin.
 
The Eclipse Che plug-in is here: https://github.com/eclipse/che-plugin-registry/tree/master/v3/plugins/redhat/mta

The sidecar image which we'd need to productize is docker.io/windup3/rhamt-vscode-extension:java8
