我很难在我的 Spring Boot 项目中设置 LiquiBase。我尝试查看文档并找到一些指南 - 但它们似乎相互矛盾。
我希望通过 Gradle 使用 LiquiBase，我希望它从 Hibernate 生成变更日志，并以一个 SQL 脚本结束，我可以在服务器上运行以将模式更新到适当的版本。
为了让它通过 Gradle 运行，我正在使用这个插件 https://github.com/liquibase/liquibase-gradle-plugin 使用他们的 README 中显示的推荐设置。
为了让 Hibernate diff 工作，我正在使用 https://github.com/liquibase/liquibase-hibernate
这是我的build.gradle文件：

通过
运行它> .\gradlew diffChangeLog -PrunList=main
但是失败了
任务：diffChangeLog liquibase-plugin：运行“主要”活动...于 2018 年 9 月 26 日星期三 13:36:24 CEST（版本 3.6.2）启动 Liquibase 建于 2018-07-03 11:28:09) 线程“main”中的异常 java.lang.NoClassDefFoundError: 组织/springframework/core/io/ClassPathResource 在 liquibase.ext.hibernate.database.HibernateSpringPackageDatabase.isXmlFile(HibernateSpringPackageDatabase.java:54)
貌似找不到Spring Boot。所以我然后尝试删除
liquibaseRuntimeliquibaseRuntime似乎我陷入了一个循环。设置它的明智方法是什么？ 我真的不想重复
liquibaseRuntimedependencies { // All of your normal project dependencies would be here in addition to... liquibaseRuntime 'org.liquibase:liquibase-core:3.6.1' liquibaseRuntime 'org.liquibase:liquibase-groovy-dsl:2.0.1' liquibaseRuntime 'mysql:mysql-connector-java:5.1.34' }
注意
// 除了...之外，您所有的正常项目依赖项都将在这里
为什么会这样？
此外，我注意到您必须编写两次数据库配置。为什么已经在 spring boot 配置中设置了它？
所以把
liquibaseRuntimeliquibaseRuntime('org.liquibase:liquibase-core:3.6.2')
liquibaseRuntime('org.liquibase:liquibase-groovy-dsl:2.0.1')
liquibaseRuntime('org.liquibase.ext:liquibase-hibernate5:3.6')
liquibaseRuntime('com.oracle.jdbc:ojdbc8:12.2.0.1')
liquibaseRuntime('org.springframework.boot:spring-boot-starter-data-jpa')
liquibaseRuntime files('src/main')
使错误消失。但它仍然不起作用。
运行此命令：
.\gradlew diff
给我这个输出：
> Task :diff

我知道这是一个旧线程，但我想为那些后来找到这个答案的人添加一些说明......
liquibaseRuntimesrcSets.main.output评论说“除了......之外，你所有的正常项目依赖项都会在这里”指的是你将在块中有一堆其他依赖项来构建和运行你的项目，而不是他们会
liquibaseRuntimeliquibaseRuntimeconfigurations.liquibaseRuntime.extendsFrom configurations.runtimeconfigurationsliquibaseRuntime.extendsFrom runtime我希望这有帮助。
这就是我使用 Gradle 6.3.0 的方式：
configurations {
liquibaseRuntime.extendsFrom runtimeClasspath
}
dependencies {
liquibaseRuntime sourceSets.main.output
}
