Extract whole schema from oracle database to another (java) (automation)
Have you considered Oracle Data Pump? With it you can export data and/or schema metadata from one database and import it into another. There is a command line interface and a PL/SQL API.
There is the liquibase runner plugin. Have you tried that?
Alternatively, you could install liquibase on the jenkins build agent and just execute it as a command line tool.
You might be not need to have plugin for Jenkins but simple Gradle task to run in Jenkinsfile.I use Gradle plugin with config like:
task updateSQL(type: JavaExec) { group = "Liquibase" classpath configurations.liquibase main = "liquibase.integration.commandline.Main" args "--changeLogFile=***/changelog-current.xml" args ****}
This valid for plugin: 'net.saliman:gradle-liquibase-plugin:XXX'
