• 我正在尝试使用Liquibase创建不存在的数据库.

• 我已经下载了MySQL并且未进行任何更改

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

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

我的maven插件代码如下

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>

运行mvn clean install时，我看到错误

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]

我该如何解决?

推荐答案

好像您没有在配置中传递用户名或密码:

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

( <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>
