How to make dependabot to keep same version for multiple Java libraries?

[IvanPizhenko]

Is there an existing issue for this?

Feature description

In my build.gradle.kts I have multiple libraries that are released simultaneously with the same version and must be kept that way. How do I make Github's Dependabot to update version of all of them at once, if it has detected that version change on one of the libraries?

Example:

  // these all must have the same version
  kapt("io.javalin.community.openapi:openapi-annotation-processor:5.3.2")
  api("io.javalin.community.openapi:javalin-openapi-plugin:5.3.2")
  api("io.javalin.community.openapi:javalin-swagger-plugin:5.3.2")
  api("io.javalin.community.openapi:javalin-redoc-plugin:5.3.2")

So far I have no idea how to achieve this.
If this is completely not supported, could be a good feature to have.

If you extract the version as a property, then dependabot should update all of them at once

Thanks @yeikel!

This sounds like a duplicate of:

• Support grouping for "must-be-updated-together" dependencies #1296

However, @yeikel 's workaround looks reasonable...
