Hi Igniters. There is a need to test backward compatibility with previous release within a task[1].
As far as I understand: it needs to provide methods in the Ignite-test-framework to start instance of specific version of Ignite. I popose to add such api in the project, for example: "Ignite startGrid(String ver)" My main idea of implementation is: 1) download "jar" from the Maven repo 2) Wrap it in a custom classloader 3) Start instance via the classloader I've created a ticket[2] for this task. Guys, please, share your thoughts about described problem and ways of implementation? [1] BinaryMarshaller should write ints in "varint" encoding where it makes sense <https://issues.apache.org/jira/browse/IGNITE-5097> [2] Provide API to test compatibility with old releases <https://issues.apache.org/jira/browse/IGNITE-5732> -- Best Regards, Vyacheslav D.
