我正在尝试使用KotlinSping Boot ，jpa和PostgreSQL配置flyway。我的gradle依赖项是：

dependencies {
    implementation('org.springframework.boot:spring-boot-starter-data-jpa')
    implementation('org.springframework.boot:spring-boot-starter-web')
    implementation('com.fasterxml.jackson.module:jackson-module-kotlin')
    implementation('org.flywaydb:flyway-core')
    implementation('com.google.code.gson:gson')
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    runtimeOnly('org.postgresql:postgresql')
    testImplementation('org.springframework.boot:spring-boot-starter-test')
}

我的application.properties文件是：

spring.datasource.driverClassName=org.postgresql.Driver
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.datasource.url=jdbc:postgresql://${JDBC_DATABASE_URL}/jpaTestDatabase
spring.datasource.username=${JDBC_DATABASE_USERNAME}
spring.datasource.password=${JDBC_DATABASE_PASSWORD}

flyway.baseline-on-migrate=true
flyway.locations=classpath:src/main/kotlin/db/migration

spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=validate
spring.session.store-type=none

使用jpa和hibernate创建表和条目可以正常工作。但是，在空数据库上执行示例迁移会导致：

org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: 
Invocation of init method failed; nested exception is org.flywaydb.core.api.FlywayException: 
Found non-empty schema(s) "public" without schema history table! Use baseline() or set baselineOnMigrate to true to initialize the schema history table.

我的目录结构是由spring initializr生成的默认结构，我的迁移位于：demo/src/main/kotlin/db/migration
我只有一个单一的迁移，这是kotlinized版本的示例迁移发现here，我适应了这一行：

class V1__Sample : BaseJavaMigration() {
  override fun migrate(context: Context?) {
    val statement = context?.connection?.prepareStatement(
      """
        CREATE TABLE article (
          id bigserial primary key,
          name varchar(20) NOT NULL,
          desc text NOT NULL
        );
      """
    )
    statement.use { it?.execute() }
  }
}

我错过了什么？为什么Flyway一直抱怨在没有模式历史表的情况下找到非空的模式“public”，而数据库是完全空的（干净的docker镜像）？
