Atlassian Update - Oct 2022

The Confluence DC development team has added a section for confluence-compat-lib usage with Struts2. The layer for Struts2 compatibility has been added in 1.5.0 of confluence-compat-lib.

We would like to say thank you for everyone who provided feedback for the compatibility layer and would continue to watch the ticket/community post for the same.

Regards,
The Confluence DC Team

Issue Summary

Since Struts 2 upgrade is a breaking change, plugins would require a compatibility layer to keep a single version running across 7.x/8.x of Confluence.

We can provide it to cover >90% of the cases. This would help in reducing friction in Vendor adoption of 8.0

Few compatibility layers required inside confluence-compat-lib would need to cater for:

Constants

ActionContext/ServletActionContext

VelocityUtils bridge for static methods(if needed)

This is reproducible on Data Center: (yes)

Steps to Reproduce

Use Struts based Confluence 8.0

Expected Results

Single version of plugin using ServletActionContext can work with both Confluence 7.x and 8.x

Actual Results

Currently, two different versions are required.

Workaround

Currently there is no known workaround for this behavior. Plugins would need two versions for compatibility.
