liquibase.update 不执行带有 runAlways 的 Liquibase changeSet

Question

I am struggling to reload data from a .csv file using runAlways="true" attribute. My goal is to rewrite(update) application version read from app_version.csv file in case the value changed. If changed, I use Liquibase API to run liquibase.update(..) which should trigger the changeSet that has section.

My pom.xml:

...
        <!-- Persistance DEPS -->
        <dependency>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-core</artifactId>
        </dependency>
        <dependency>
            <groupId>org.liquibase.ext</groupId>
            <artifactId>liquibase-hibernate5</artifactId>
            <version>3.6</version>
        </dependency>
...

Application.properties:

spring.liquibase.change-log=classpath:db/changelog/db.changelog-master.xml
spring.liquibase.contexts=prod
spring.liquibase.enabled=true
# H2
spring.datasource.url=jdbc:h2:file:~/author-db/testdb
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver

DB table global_settings (using H2 in file at the moment, pk="id"):

ID | APP_KEY    |   APP_VALUE    | CREATED_BY | CREATED_DATE           | LAST_MODIFIED_BY | LAST_MODIFIED_DATE  
1   app-version   4.3.3-SNAPSHOT     system     2020-01-21 16:11:10.009     system                     null

The .xml file containing the changeSet:

<?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">

  <changeSet id="app_version" author="author">
    <loadData file="db/app_version.csv" separator=";"
      tableName="global_settings">
      <column name="id" type="numeric"/>
      <column name="created_date" type="timestamp"/>
      <column name="last_modified_date" type="timestamp"/>
    </loadData>
  </changeSet>

  <changeSet id="update_app_version" author="author" runAlways="true">
    <loadUpdateData file="db/app_version.csv" separator=";" tableName="global_settings"
      primaryKey="id">
      <column name="id" type="numeric"/>
      <column name="created_date" type="timestamp"/>
      <column name="last_modified_date" type="timestamp"/>
    </loadUpdateData>
  </changeSet>
</databaseChangeLog>

Contents of the app_version.csv file:

id;app_key;app_value;created_by;last_modified_by
1;app-version;@project.version@;system;system

Java code used to run:

inside main spring boot class
...

Optional<GlobalSettings> appSettings =  globalSettingsRepository.findOneByAppKey("app-version"); --> value = 4.3.3-SNAPSHOT
appSettings.get().setValue("4.3.2"); --> value = 4.3.2
globalSettingsRepository.save(appSettings.get());
runLiquibaseUpdate(); --> value = 4.3.2

--------------
public void runLiquibaseUpdate() {
    Database database;
    Connection connection;
    Liquibase liquibase;
    try {
      connection = DriverManager.getConnection(env.getProperty("spring.datasource.url"),
          env.getProperty("spring.datasource.username"),
          env.getProperty("spring.datasource.password"));
      database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(new JdbcConnection(connection));

      DatabaseChangeLog changeLog = new DatabaseChangeLog(env.getProperty("spring.liquibase.change-log"));
      liquibase = new Liquibase(changeLog, new FileSystemResourceAccessor(), database);
      liquibase.update(new Contexts(), new LabelExpression());
    } catch (SQLException | LiquibaseException e) {
      e.printStackTrace();
    }
  }

My intention was this: first changeSet (id="app_version") loads the data from .csv file, works. After runLiquibaseUpdate method is run, per my understanding (please correct me if I'm wrong), it should trigger the changeSet(id="update_app_version") due to runAlways="true" and the value in the database should change to the initial value found in .csv file, but it doesn't.

So far, I have not been able to pinpoint the cause of the problem, logs are not showing anything after method is finished.

If my understanding is wrong and this is not doable, I kindly ask for an advice on how to achieve this.

The changelog you have defined in your Application.properties is only valid for the prod context but you have called liquibase in no-context mode:

spring.liquibase.contexts=prod

So either remove the entry in the properties file or provide it to liquibase:

 liquibase.update(new Contexts("prod), new LabelExpression());
