Liquibase 日志级别问题和许可证错误

Question

当运行命令时，我在社区版中遇到许可证错误：

2019-09-13 10:07:35 checking if license is installed
2019-09-13 10:07:35 Problem verifying the license.
net.java.truelicense.core.LicenseManagementException: java.io.FileNotFoundException

看起来一切正常，但这个错误确实让我有点担心。

首先，当运行命令时，我在让 liquibase-3.8.0 记录任何内容时遇到了一些问题，例如.\liquibase.bat更新。

我最终通过将一些 janino jar 和日志配置添加到 lib 文件夹来解决这个问题。

janino-3.1.0.jar
commons-compiler-3.1.0.jar
logback.xml

现在我得到了这样的预期日志：

2019-09-13 10:07:35 Successfully acquired change log lock

2019-09-13 10:07:36 Liquibase: Update has been successful.

但是我在日志的开头也遇到了这个错误：

这是我应该关心的事情，还是我应该忽略它？

Answer 1

这不是什么值得担心的事情。 Liquibase 和 Datical 最近添加了新的扩展功能作为 Liquibase Pro。此新功能需要付费商业许可证（可免费试用）。如果许可证不可用，您将看到这样的消息。

免责声明：我为 Datical 工作并编写了一些有问题的代码，并且让它像这样转储堆栈跟踪是一个将在未来版本中解决的问题。
