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>
