How to properly configure Liquibase in Spring Boot with Maven plugin so that a I can run diff command using latest version
问题
当我尝试执行 liquibase diff 命令时，我得到了以下错误：
ERROR [liquibase.integration.commandline.Main]: 在运行 Liquibase 时出现意外错误: java.lang.RuntimeException: 无法找到数据库驱动程序: liquibase.ext.hibernate.database.connection.HibernateDriver
我猜这可能与版本或缺少的依赖项有关，所以这是我 POM.XML 文件的一部分：
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

我已经安装了 liquibase 3.10.2 版本 - Mac OS，我使用的是 postgres 数据库。此外，这是我 liquibase 属性文件的一部分：
username=postgres
password=
driver=org.postgresql.Driver
referenceDriver=liquibase.ext.hibernate.database.connection.HibernateDriver
referenceUrl=hibernate:spring:com.something.something.models?dialect=org.hibernate.dialect.PostgreSQLDialect```

When I try to execute ```liquibase diff``` command, I get the following error:
*ERROR [liquibase.integration.commandline.Main]: Unexpected error running Liquibase: java.lang.RuntimeException: Cannot find database driver: liquibase.ext.hibernate.database.connection.HibernateDriver*
I assume it might have something to do with versions or missing dependencies so here is part of my POM.XML file:
```<parent>

I've installed liquibase 3.10.2 version - Mac OS and I use postgres. Also, here is part of my liquibase properties file:
username=postgres
password=
driver=org.postgresql.Driver
referenceDriver=liquibase.ext.hibernate.database.connection.HibernateDriver
referenceUrl=hibernate:spring:com.something.something.models?dialect=org.hibernate.dialect.PostgreSQLDialect```

我已切换到版本4.0.0并更新了pom.xml如下：
```xml
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>4.0.0</version>
<configuration>
<propertyFileWillOverride>true</propertyFileWillOverride>
<propertyFile>src/main/resources/liquibase.properties</propertyFile>
</configuration>
<dependencies>
<dependency>
<groupId>org.liquibase.ext</groupId>
<artifactId>liquibase-hibernate5</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.7.3.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>2.0.1.Final</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>${spring-boot.version}</version>
</dependency>
</dependencies>
</plugin>
现在，运行mvn liquibase:diff命令会生成差异文件。
英文:
I've switched to version 4.0.0 and updated pom.xml to following:
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>4.0.0</version>
<configuration>
<propertyFileWillOverride>true</propertyFileWillOverride>
<propertyFile>src/main/resources/liquibase.properties</propertyFile>
</configuration>
<dependencies>
<dependency>
<groupId>org.liquibase.ext</groupId>
<artifactId>liquibase-hibernate5</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.7.3.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>2.0.1.Final</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>${spring-boot.version}</version>
</dependency>
</dependencies>
</plugin>
Now, mvn liquibase:diff command generates diff file.
