我正在尝试在现有数据库和我们的 Spring JPA 应用程序之间生成差异更改日志。现在生成初始更改日志已成功，对于差异，我设法解决了类路径问题(在 StackOverflow 答案的大力帮助下)，但现在我陷入了差异更改日志。
这是我在 gradlew :dbinit:diffChangeLog 上遇到的错误:

非常感谢您的帮助!
最佳答案
我认为您之前已经运行过gradle clean或者不会编译您的project java文件
如果您仔细阅读您的异常，您肯定能够解决您的问题。
正如我所看到的，您的异常层次结构是这样的
liquibase: Unable to resolve persistence unit root URL
liquibase.exception.DatabaseException: javax.persistence.PersistenceException: Unable to resolve persistence unit root URL
这意味着您编译的类在您的类路径中不可用，并且 liquibase 只扫描到您的类路径中。
Now if you see your stacktrace at bottom it clearly throws
FileNotFoundExceptionit means there is no class available at classpath
Caused by: java.io.FileNotFoundException: class path resource [] cannot be resolved to URL because it does not exist
所以，现在找到解决方案，您需要在使用 diff 之前编译所有类，然后 liquibase 在类路径上找到该类并与数据库进行比较，然后生成更改日志并将其附加到您diffChangeLog 文件。
:)
请在针对您的 java 类生成 diff 之前运行 gradlecompile
关于gradle - 无法让 Liquibase gradle 插件与 Spring JPA 应用程序一起使用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40473197/
