Liquibase 缺少 postgresql 缺少数据库驱动程序

【问题标题】：Liquibase missing postgresql missing database driverLiquibase 缺少 postgresql 缺少数据库驱动程序
【发布时间】：2021-10-05 16:20:51
【问题描述】：

我们最近从 bash 中的纯 PostgreSQL 开发过渡到了 Liquibase 更新，我很难让应用程序运行起来。

这是我的配置文件 (liquibase.properties)

####     _     _             _ _
##      | |   (_)           (_) |
##      | |    _  __ _ _   _ _| |__   __ _ ___  ___
##      | |   | |/ _` | | | | | '_ \ / _` / __|/ _ \
##      | |___| | (_| | |_| | | |_) | (_| \__ \  __/
##      \_____/_|\__, |\__,_|_|_.__/ \__,_|___/\___|
##                  | |
##                  |_|
##
##      The liquibase.properties file stores properties which do not change often,
##      such as database connection information. Properties stored here save time
##      and reduce risk of mistyped command line arguments.
##      Learn more: https://www.liquibase.org/documentation/config_properties.html
####
####
##   Note about relative and absolute paths:
##      The liquibase.properties file requires paths for some properties.
##      The classpath is the path/to/resources (ex. src/main/resources).
##      The changeLogFile path is relative to the classpath.
##      The url H2 example below is relative to 'pwd' resource.
####
# Enter the path for your changelog file.
changeLogFile=db/changelog/master.xml

#### Enter the Target database 'url' information  ####
#liquibase.command.url=jdbc:h2:tcp://localhost:5432/foo
liquibase.command.url=jdbc:postgresql://localhost:5432/foo

# Enter the username for your Target database.
liquibase.command.username: my_username

# Enter the password for your Target database.
liquibase.command.password: my_password

每次我运行它时，它总是抱怨缺少一些数据库驱动程序

$ liquibase update

谁能帮我解决这个问题？

【问题讨论】：

  • 嗯，您没有在属性文件或命令行中指定驱动程序的 jar 文件的位置。您如何期望 liquibase 知道您将驱动程序放在哪里？

标签： sql postgresql liquibase sql-update


【解决方案1】：

您是否已经将 postgrest JDBC jar 复制到了liquidbase/lib 中？ https://docs.liquibase.com/workflows/database-setup-tutorials/postgresql.html

【讨论】：

  • 我建议不要在答案中使用修辞问题。他们冒着被误解为根本不是答案的风险。您正在尝试回答此页面顶部的问题，不是吗？否则请删除此帖。
  • 请将其表述为有条件的解释性答案，以避免给人以澄清问题而不是回答的印象（应该使用评论而不是答案，比较meta.stackexchange.com/questions/214173/…）。例如像“如果你的问题是......那么解决方案是......因为......。”
  • 虽然此链接可能会回答问题，但最好在此处包含答案的基本部分并提供链接以供参考。如果链接页面发生更改，仅链接答案可能会失效。 - From Review
