我正在使用带有 Gradle 的 JHipster 4.5.4 作为构建系统，并希望添加 Gradle 任务以执行 Liquibase 任务，例如验证或重置。我使用 JHipster 附带的 liquibaseDiffChangelog 任务作为模板。此任务定义如下：

task liquibaseDiffChangelog(dependsOn: compileJava, type: JavaExec) {
    group = "liquibase"

    if (OperatingSystem.current().isWindows()) {
        dependsOn pathingLiquibaseJar
        doFirst {
            classpath = files(pathingLiquibaseJar.archivePath)
        }
    } else {
        classpath sourceSets.main.runtimeClasspath
        classpath configurations.liquibase
    }
    main = "liquibase.integration.commandline.Main"

    args "--changeLogFile=src/main/resources/config/liquibase/changelog/" + buildTimestamp() +"_changelog.xml"
    args "--referenceUrl=hibernate:spring:at.project.domain?dialect=org.hibernate.dialect.MySQL5InnoDBDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy"
    args "--username=testapp_db_user"
    args "--password=secret"
    args "--url=jdbc:mysql://localhost:3306/testapp_db"
    args "--driver=com.mysql.jdbc.Driver"
    args "diffChangeLog"
}

我从简单地用validate交换diffChangeLog开始，然后收到类路径错误。我还添加了一个类路径参数，最终得到了这样的任务定义：

task liquibaseValidate(dependsOn: compileJava, type: JavaExec) {
    group = "liquibase"

    if (OperatingSystem.current().isWindows()) {
        dependsOn pathingLiquibaseJar
        doFirst {
            classpath = files(pathingLiquibaseJar.archivePath)
        }
    } else {
        classpath sourceSets.main.runtimeClasspath
        classpath configurations.liquibase
    }
    main = "liquibase.integration.commandline.Main"

    args "--changeLogFile=./build/resources/main/config/liquibase/master.xml"
    args "--referenceUrl=hibernate:spring:at.project.domain?dialect=org.hibernate.dialect.MySQL5InnoDBDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy"
    args "--username=testapp_db_user"
    args "--password=secret"
    args "--url=jdbc:mysql://localhost:3306/testapp_db"
    args "--driver=com.mysql.jdbc.Driver"
    args "--classpath=./build/resources/main/config/liquibase/changelog/"
    args "validate"
}

主文件被读取，因为它提到了正确的文件名，所以这部分很好。但它无法识别master.xml文件中引用的实际变更集文件的路径。这是错误消息：

如何正确添加类路径？

与此 JHipster 问题相关，您需要classpath:从 master.xml（位于src/main/resources/config/liquibase/master.xml）中的更改日志路径中删除。这将允许您使用除 liquibaseDiffChangeLog 之外的其他 liquibase 任务。这应该在下一个版本（v4.6.2+）中修复。
