使用 Spring 应用程序将 Liquibase 嵌入到 jar 中
Embedding Liquibase in a jar with Spring Application
我在尝试使用 liquibase 在 uberjar 中嵌入纯 Spring（不是 Spring 启动）应用程序时遇到了一个非常具体的错误。 SpringLiquibase bean 一初始化，它就开始寻找我不明白的东西：
WARNING 7/16/15 3:22 PM: liquibase: No Liquibase-Packages entry found in MANIFEST.MF. Using fallback of entire 'liquibase' package
WARNING 7/16/15 3:28 PM: liquibase: Error initializing SpringLiquibase

我知道 MANIFEST.MF 中的 Liquibase-Package 条目并使用 shade 插件填充它（虽然我不明白它有什么用）并使用 shade 插件放置它，但它没有'没有任何效果。 liquibase 在寻找什么，我该如何克服这些错误？
根据此 issue，如果您创建 src/main/webapp 文件夹，此问题将得到解决：
Incidentally, the root cause is that no src/main/webapp folder exists. As a work around you could create one or set a value in @WebAppConfiguration that points to classpath: folder that actually exists.
