SpringBoot Maven Dependency Exclusion does not work anymore for war archive since version 2.5.0

Maven Dependency Exclusion does not work anymore for war archive since version 2.5.0.

If i downgrade to version 2.4.7, exclusion of dependencies is correct during repackage Maven goal.

In think the root cause is this commit : https://github.com/spring-projects/spring-boot/commit/152698f2b23168908ce45721cdbb0d1c0e5dd280#diff-e7a76a5f4e121a18180b454ce4290ca7fc458584efcc82309730c57c73762080R187

@antoine777 We have an open issue for fixing exclusions with WAR files. AFAIK it hasn't work at all yet so I am a bit surprised that it used to work for you in 2.4. Could you provide a sample that we can run to reproduce the working behavior in 2.4 and the issue you're seeing in 2.5?

In fact, i need to configure exclusions in 2 maven plugins to achieve my goal - maven-war-plugin (packagingExcludesoption) - spring-boot-maven-plugin (excludesoption)

Project sample :

In version 2.4.7, spring-tx and batik-ext are removed from final springboot war

Thanks. The use of packagingExcludes was the key difference here. https://github.com/spring-projects/spring-boot/issues/15808 has now been fixed and the problem no longer occurs with 2.5.2-SNAPSHOT, even without the <packagingExcludes>.
