模式验证：缺少表

Question

我想使用 liquibase 在数据库中创建表，但他没有出现，我收到关于缺少表的错误。有人能告诉我我做错了什么吗？

在 application.yml 我有 spring.jpa.hibernate.ddl-auto=validate

创建活动表.xml：

<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                   xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.4.xsd">

    <changeSet author="Damian Malicki" id="create-activities-table.xml">
        <createTable tableName="activity">
            <column name="id" type="varchar(255)">
                <constraints primaryKey="true" nullable="false" />
            </column>
            <column name="description" type="varchar(255)">
                <constraints nullable="false" />
            </column>
            <column name="created_by_id" type="varchar(255)">
                <constraints nullable="false" />
            </column>
            <column name="type" type="varchar(255)">
                <constraints nullable="false" />
            </column>
            <column name="created_on" type="datetime">
                <constraints nullable="false" />
            </column>
        </createTable>
    </changeSet>
</databaseChangeLog>

数据库变更日志：

databaseChangeLog:
  - include:
      file: classpath:db/changelog/activities/create-activities-table.xml

活动实体：

@Getter
@Setter
@Builder
@NoArgsConstructor
@AllArgsConstructor
@Entity
@Table(name = "activity")
public class ActivityEntity {
    @Id
    @Column(name = "id")
    private String id;
    @Column(name = "description")
    private String description;
    @Column(name = "created_by_id")
    private String createdById;
    @Column(name = "type")
    private ActivityType type;
    @Column(name = "created_on")
    private LocalDateTime createdOn;
//    @OneToMany(mappedBy = "activitiesId")
//    private List<ActivityParamEntity> activityParamEntityList;


}

我已经尝试重写代码，重写它并没有任何改变。

当我尝试 liquibase 更新时出现：

liquibase : The term 'liquibase' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, veri 
fy that the path is correct and try again.
