即使我有 liquibase.properties 文件，也未指定数据库 URL

如何解决即使我有 liquibase.properties 文件，也未指定数据库 URL

我正在尝试使用 liquibase 运行我的迁移，但由于某些原因，我的 pom 文件找不到我的属性文件。当我运行更新命令时，出现以下错误

The database URL has not been specified either as a parameter or in a properties file.

我使用 exections 标记是因为我希望有多个数据库连接到我的应用程序。 在我添加该标签之前，一切正常

pom 文件

解决方法

使用执行时，您必须告诉 Maven 运行哪个目标，以及哪个阶段负责运行目标，如 general plugin config docs 中所述。

当您在顶级 <configuration> 块中指定属性文件时，它适用于所有插件执行。

<executions>
  <execution>
    <configuration>
      <phase>[Maven phase]</phase>
      <goals>
          <goal>[plugin goal to run]</goal>
      </goals>
      <propertyFile>src/main/resources/liquibase.properties</propertyFile>
    </configuration>
  </execution>
</executions>
