How to create database with Liquibase

问题

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?

回答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>
