https://vertx.io/blog/from-vert-x-3-to-vert-x-4/ :

Vert.x 3 will con­tinue to get bug fix re­leases of­fi­cially until Jan­u­ary 2023.

FOLIO's Morning Glory support period exceeds January 2023.

Therefore all modules must migrate from Vert.x 3 to Vert.x 4 for Morning Glory.

mod-template-engine currently uses Vert.x 3.7.1 and needs to migrate to Vert.x 4.

Affected pom.xml section:

<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-junit5</artifactId>
<version>3.7.1</version>
<scope>test</scope>
</dependency>
Consider using the version provided by vertx-stack-depchain by removing the <version> line:

<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-junit5</artifactId>
<scope>test</scope>
</dependency>
The same for the other vertx dependency entries in pom.xml.
