Spring boot Liquibase classpath based migration files

Question

I'm unable to get liquibase migration working with Spring Boot when I'm deploying the app in a docker container. I have a fat jar which is extracted when the docker image is created.

I have a separate module where I keep my migration files. I am able to load the master.xml:

<includeAll path="classpath*:/changelog" relativeToChangelogFile="false" />

It then goes on and loads the rest of the resources. The problem is that SpringResourceOpener.java then extracts the real path from loaded resources which is still ok:

jar:file:/app/lib/database-0.0.1-SNAPSHOT.jar!/changelog/001-categories-table.xml

But then does some path manipulations which ends up with:

lib/database-0.0.1-SNAPSHOT.jar/changelog/001-categories-table.xml

Which in turn is not a valid classpath path:

Caused by: java.io.FileNotFoundException: class path resource 
[lib/database-0.0.1-SNAPSHOT.jar/changelog/001-categories-table.xml]
cannot be resolved to URL because it does not exist

I either need the /changelog/001-categories-table.xml (classpath) or file:/app/lib/database-0.0.1-SNAPSHOT.jar!/changelog/001-categories-table.xml to be able to read the file. But it always ends up the incomplete path as above.

Is this a configuration issue or there is a way to tweak this behaviour?

I was able to get it to work with manually referencing the change log files with include in master.xml rather than includeAll.

e.g.

<!--includeAll path="changelog" relativeToChangelogFile="false" /-->

<include file="changelog/001-table.xml" />
<include file="changelog/002-table.xml" />
<include file="changelog/003-table.xml" />
<include file="changelog/004-table.xml" />
