Hello @rsclarke-vgw,

Thanks for reporting this! We will need to look into what upgrades will be necessary to get the builds passing again.

This issue has been added to our internal backlog to be prioritized. Pull requests and +1s on the issue summary will help it move up the backlog.

With best regards,

Elmer

The problem here is this is not being actively maintained;

• Use a newer version of Gradle that builds on modern JVM versions. #436
• Upgraded gradle wrapper to 4.10.2 and fatjar to 0.3 #459

PR's are being raised to update gradle going back to early last year yet never merged. :/

Plus one for this. 1 year seems a decently scary amount of time for builds to be failing!

BUMP - These failed builds and stale PRs dont look good SendGrid team

@rsclarke-vgw any updates on this?

[rsclarke-vgw]

@partySquirrel Nope. It doesn't look like this project is getting prioritised at all from SendGrid.
