## Description
CLI cannot find liquibase.properties inside jar file with resources

## Steps To Reproduce
* put liquibase.properties inside jar file with database changelog and chagesets. in my case it is DatabaseUpdateResources.jar
* replace path to liquibase.jar, database driver jar and jar with resouurces in command below and run it
* java -cp "${path_to_jar}\liquibase.jar;${path_to_jar}\DatabaseUpdateResources.jar;${path_to_database_driver_jar}{database_driver.jar}" liquibase.integration.commandline.Main --logLevel=info update

## Actual Behavior
Errors:
The option --url is required.
The option --changeLogFile is required.

## Expected/Desired Behavior
liquibase used options from liquibase.properties inside jar in classpath.

## Additional Context
in version 3.5.3 cli update with properties file in jar worked correctly, this problem happened after updating to 4.2.0.
