How to create database with Liquibase

Question

• I am trying to use Liquibase to create database that does not exists.

• I have downloaded MySQL and not made any change in it

• My maven plugin code looks like

  <plugins>
      <plugin>
          <groupId>org.liquibase</groupId>
          <artifactId>liquibase-maven-plugin</artifactId>
          <version>3.1.1</version>
          <configuration>
              <changeLogFile>src/main/resources/changelog.xml</changeLogFile>
              <driver>com.mysql.jdbc.Driver</driver>
              <url>jdbc:mysql://localhost:3306/myApp?createDatabaseIfNotExist=true</url>
          </configuration>
          <executions>
              <execution>
                  <phase>process-resources</phase>
                  <goals>
                      <goal>update</goal>
                  </goals>
              </execution>
          </executions>
      </plugin>
  </plugins>
  

When I run mvn clean install, I see error as

Failed to execute goal org.liquibase:liquibase-maven-plugin:3.1.1:update (default) on project database_seed: Error setting up or running Liquibase: liquibase.exception.DatabaseException: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user ''@'localhost' to database 'myApp' -> [Help 1]

How do I fix it?

Answer 1

Looks like you're not passing a username or password as part of your config:

(from the liquibase maven documentation)

<configuration>
  <changeLogFile>src/main/resources/changelog.xml</changeLogFile>
  <driver>com.mysql.jdbc.Driver</driver>
  <url>jdbc:mysql://localhost:3306/myApp?createDatabaseIfNotExist=true</url>
  <username>liquibaseTest</username>
  <password>pass</password>
</configuration>
