我可以通过maven build（liquibase:update目标）运行Liquibase changelog，没有任何问题。现在，我希望Liquibase根据所选的Maven配置文件使用从属性文件（db.properties）加载的数据库凭据和URL：

|-- pom.xml
`-- src
    `-- main
        `-- resources
            |-- local
            |   `-- db.properties
            |-- dev
            |   `-- db.properties
            |-- prod
            |   `-- db.properties
            `-- db-changelog-master.xml
            `-- db-changelog-1.0.xml

3个属性文件中的每个文件都将如下所示：

database.driver = oracle.jdbc.driver.OracleDriver
database.url = jdbc:oracle:thin:@<host_name>:<port_number>/instance
database.username = user
database.password = password123

现在，我不想在POM文件中定义这些属性（如liquibase using maven with two databases does not work问题的公认答案中所述），而是希望从外部属性文件中加载它们。

1.我在POM文件中使用了Maven的resource元素：

<build>
      <pluginManagement>
         <plugins>
            <plugin>
               <groupId>org.liquibase</groupId>
               <artifactId>liquibase-maven-plugin</artifactId>
               <version>3.1.0</version>
               <configuration>
                  <changeLogFile>db.changelog-master.xml</changeLogFile>
                  <verbose>true</verbose>
               </configuration>
            </plugin>
         </plugins>
      </pluginManagement>
   </build>

<profiles>
    <profile>
        <id>local</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <build>
            <resources>
                <resource>
                    <directory>src/main/resources/local</directory>
                </resource>
            </resources>
        </build>
        <properties>
            <liquibase.url>${database.url}</liquibase.url>
            <liquibase.driver>${database.driver}</liquibase.driver>
            <liquibase.username>${database.username}</liquibase.username>
            <liquibase.password>${database.password}</liquibase.password>
        </properties>
    </profile>
    <profile>
        <id>dev</id>
        <build>
            <resources>
                <resource>
                    <directory>src/main/resources/dev</directory>
                </resource>
            </resources>
        </build>
        <properties>
            <liquibase.url>${database.url}</liquibase.url>
            <liquibase.driver>${database.driver}</liquibase.driver>
            <liquibase.username>${database.username}</liquibase.username>
            <liquibase.password>${database.password}</liquibase.password>
        </properties>
    </profile>
</profiles>

2.我尝试使用属性Maven插件：

<plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>properties-maven-plugin</artifactId>
      <version>1.0-alpha-2</version>
      <executions>
         <execution>
            <phase>initialize</phase>
            <goals>
               <goal>read-project-properties</goal>
            </goals>
            <configuration>
               <files>
                  <file>src/main/resources/local/db.properties</file>
               </files>
            </configuration>
         </execution>
      </executions>
   </plugin>

当我运行liquibase：update maven目标时，我得到这个错误：

[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.1.0:update (default-cli) on project my-project: The driver has not been specified either as a parameter or in a properties file

似乎POM文件中引用的数据库属性无法解析。
你知道怎么才能做到吗？
