Running Epsilon Server-Side [message #1837205]

We are attempting to embed Epsilon in OSGI server. We would like to use the ant automation interface as the control function for our implementation. We intended to use the eclipse-ant-launcher to execute our workflows.

It seems the ant-launcher is based on workspaces. Since the workspace are a singleton in Eclipse, it seems that only one user request can be served at a time. (one Eclipse instance = one user = one workspace).

Is there any way to execute Epsilon as a service, short of creating a two-step hand-off with multiple instances (servers?) We intend to reuse existing EMF tools, so we would like to continue using OSGI.

Hi Joern,

If I understand correctly, this sounds like an issue with any ANT tasks, not just Epsilon's. If this is the case, other options I can think of is to check if there's a Gradle plugin that offers any better support for OSGi (see [1] for running Epsilon's ANT tasks from Gradle), or to forgo ANT altogether and use Epsilon's API directly in your service.

Thanks,
Dimitris
