Question

我已经设置了一个带有3个模块的弹簧启动项目（父级）。

-- parent
  --module 1
  --module 2
  --module 3

现在我想将一个新的maven项目添加为这个父项目的新模块。

新的maven项目正在使用 liquibase-maven-plugin ，并且作为单个项目非常适合。但是当我尝试将新的maven项目集成到父项目时，它就失败了。

Failed to execute goal org.liquibase:liquibase-maven-plugin:3.5.3:update (default) 
on project database-migration: Error setting up or running Liquibase: 
liquibase.exception.DatabaseException: liquibase.exception.DatabaseException: 
Connection could not be created to ${database.url} with driver org.postgresql.Driver.  
Possibly the wrong driver for the given database URL

当我将此父节添加到我的新模块项目时，liquibase-maven-plugin无法再替换${database.url}文件中定义的占位符liquibase.properties：

<parent>
    <artifactId>backend-parent</artifactId>
    <groupId>xyz</groupId>
    <version>0.1.0-SNAPSHOT</version>
</parent>

父/超POM看起来像：

liquibase属性

url: ${database.url}
username: ${database.username}
verbose: true
contexts: ${environment}

正如我所说的，没有新模块POM中的父节，工作正常。我使用这个cmd来构建迁移。

mvn clean install -Pupdate-db -Denv=local

我确实试过这里描述的几个变通方法：

感谢您的任何建议。

与liquibase maven插件和spring boot冲突
