Problem

The Maven Wrapper pass added mvnw.cmd and .mvn/wrapper/maven-wrapper.properties, which carry the Apache wrapper header rather than the Apereo one. license:check maps .cmd and .properties files, so it fails on both (mvnw has no extension and is skipped).

CI doesn't notice, because it runs plain package. But uportal-portlet-parent's jasig-release profile binds license:check at validate, and maven-release-plugin activates that profile, so release:prepare / release:perform fail immediately. Where there's a release-portlet.sh, its license:format step would rewrite the wrapper files and abort on drift.

Change

• This repo had no local license-plugin config. Add a minimal block that appends mvnw, mvnw.cmd and .mvn/** to the parent's excludes (combine.children="append", so the parent list still applies).

Verification

• ./mvnw -B license:check on this branch: BUILD SUCCESS, also with a stray file under overlays/ present. On master it fails on the two wrapper files.
• ./mvnw -B -Pjasig-release validate now gets past license:check, then fails notice:check (NOTICE out of date). That failure is pre-existing on master and unrelated; notice:generate before releasing fixes it.

Notes

• Part of a fleet-wide fix for the wrapper pass. The same excludes are also going into uportal-portlet-parent as the default, but repos need this local change now to release, and repos whose <excludes> replace the parent's list wouldn't pick up a parent-only change anyway.
