Java build systems (Ant, Maven, Gradle) used to require "java-devel" because their typical usages involves code compilation, which requires full JDK.
In Fedora 23 I've just replaced hard requirement on "java-devel" with recommends. From now on Ant, Maven and Gradle require "java-headlesss" and recommend "java-devel", which means that by default they will still be installed with full JDK, but it will be possible to install and use them with just headless JRE.

Why? Most builds require javac. Unless you are only installing and not building why would you not want the java-devel?

That's exactly my point - *most*, but not all.

Ant, Maven and Gradle are generic build systems. While they are typically used for building Java projects, they are certainly capable of more.
Some examples: - Maven supports "toolkits", which allow you to compile project with third-party JDK; in this case Maven can be ran with pure JRE - Ant, Maven and Gradle can all be used to compile non-Java code (such as C) - I've seen Ant scripts used for application deployment, which don't compile anything, but download and copy files around - Maven can also be used for app deployment (for eg. wildfly:deploy) - I've seen Maven used for static website gerenation (convert Markdown to HTML, apply templates, fetch CSS and JavaScript resources from remote repos, assemble WAR file)
and so on...
I've also seen cases where a package depended on a class from the build system's jar at runtime (especially ant and maven), but the user has no intention of using the build system to build anything... They just needed to satisfy the runtime dependency. So, overall, I think this makes sense.
