How to set liquibase classpath - jhipster

Question

I created a JHipster project. I would like to run the liquibase changesets manually. By default the changesets are included from the classpath. The changelog is in src/main/resources/config/liquibase/master.xml, and the changesets are in src/main/resources/config/liquibase/changelog.
<?xml version="1.0" encoding="utf-8"?>
<databaseChangeLog
xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.5.xsd">
<include file="classpath:config/liquibase/changelog/00000000000000_initial_schema.xml" relativeToChangelogFile="false"/>
<!-- jhipster-needle-liquibase-add-changelog - JHipster will add liquibase changelogs here -->
<!-- jhipster-needle-liquibase-add-constraints-changelog - JHipster will add liquibase constraints changelogs here -->
</databaseChangeLog>
When running mvn liquibase:update, I get an error because the changesets are not in the classpath even though the file exists:
[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.5.3:update (default-cli) on project playground: Error setting up or running Liquibase: liquibase.exception.SetupException: classpath:config/liquibase/changelog/00000000000000_initial_schema.xml does not exist -> [Help 1]
So I try to run from the command line by setting the classpath.
liquibase --classpath=src/main/resources --classpath=postgresql-42.1.3.jar
--url=jdbc:postgresql://localhost:5432/playground
--driver=org.postgresql.Driver
--changeLogFile=src/main/resources/config/liquibase/master.xml
--username playground --password=***** update
with the same error: Unexpected error running Liquibase: classpath:config/liquibase/changelog/00000000000000_initial_schema.xml does not exist
A workaround is to remove the reference classpath: in the include part but I would like to avoid to edit the file each time a changeset is added by jhipster when using jhipster entity or jhipster import-jdl.

Answer 1

The solution is to run mvn process-resources before running a liquibase command, so the files under src/main/resources will be in the target/classes folder. And then remove the classpath: part as stated in https://github.com/jhipster/generator-jhipster/pull/6121

Answer 2

well... I faced the same problem due I don't want that jhipster automatically update the production database.
So starting with #Sydney suggestion I decided to write a new profile in POM that changes the 'classpath:' word in process-resources phase, and for that I used an ANT plugin for make an replacement over master.xml file to <empty>. So this was a result:
<profile>
<id>only-liquibase</id>
<build>
<plugins>
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>${liquibase.version}</version>
<configuration>
<changeLogFile>target/classes/config/liquibase/master.xml</changeLogFile>
<driver></driver>
<url></url>
<defaultSchemaName></defaultSchemaName>
<username>dentalaser</username>
<password></password>
<referenceUrl>hibernate:spring:ec.com.dentalaser.domain?dialect=&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy</referenceUrl>
<verbose>true</verbose>
<logging>debug</logging>
</configuration>
<dependencies>
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>${javassist.version}</version>
</dependency>
<dependency>
<groupId>org.liquibase.ext</groupId>
<artifactId>liquibase-hibernate5</artifactId>
<version>${liquibase-hibernate5.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>${project.parent.version}</version>
</dependency>
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>${validation-api.version}</version>
</dependency>
</dependencies>
</plugin>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>process-resources</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target>
<echo>Reemplazando el classpath el archivo a desplegar en AWS</echo>
<replace file="${project.build.directory}/classes/config/liquibase/master.xml" token="classpath:" value=""/>
</target>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
After that from command line execute something like this:
./mvnw process-resources liquibase:updateSQL -DskipTests -Dliquibase.url="jdbc:postgresql://<IP>:<PORT>/<DATABASE>" -Dliquibase.password="<supersecret>" -Ponly-liquibase
or this:
./mvnw process-resources liquibase:updateSQL -DskipTests -Dliquibase.url="offline:postgresql" -Ponly-liquibase
I really hope that this help you!!!
