Maven plugin ignores changeLogDirectory, finds two changelog files

[marcelstoer]

Environment

Liquibase Version: 4.9.1

Liquibase Integration & Version: Maven

Database Vendor & Version: I tested with Postgres and Oracle

Operating System Type & Version: I tested on macOS and Linux

Description

I appears as if the Maven plugin ignores its changeLogDirectory parameter or gives precedence to the classpath. The consequence is that it finds the changelog file selected through the changeLogFile parameter in two places.

Steps To Reproduce

• Prepare a database of choice e.g. Postgres.
• Use basic Maven project structure.
• Place a changelog file db/changelog/db.changelog-master.xml in src/main/resources.
• Run a Maven build e.g. mvn package. Maven will copy all resources to target/classes.
• Run Liquibase through Maven

mvn org.liquibase:liquibase-maven-plugin:4.9.1:update \
-Dliquibase.changeLogFile="db/changelog/db.changelog-master.xml" \
-Dliquibase.changeLogDirectory="src/main/resources" \
-Dliquibase.driver=org.postgresql.Driver \
...

Actual Behavior

Liquibase scans the classpath for the configured changelog file and finds it in two places:

[ERROR] Error Reading Changelog File: Found 2 files that match db/changelog/db.changelog-master.xml:
file:/some-dir/target/classes/db/changelog/db.changelog-master.xml,
file:/some-dir/src/main/resources/db/changelog/db.changelog-master.xml

Expected/Desired Behavior

Since I explicitly set -Dliquibase.changeLogDirectory="src/main/resources" Liquibase should only look in src/main/resources in which case it would not find two changelog files.

Additional Context

Several other issues were reported about such behavior but none specific to Maven e.g. #2818. Their potential fix through #3119 does not apply here as the changelog folder is defined.
