为什么 Maven Flyway 插件无法迁移我的 Hsqldb 数据库？

Question

我在使用 flyway 和 maven 插件初始化和迁移 HSQLDB 数据库时遇到问题。

我的 pom.xml 中有这个 XML 块：

<plugin>
    <groupId>com.googlecode.flyway</groupId>
    <artifactId>flyway-maven-plugin</artifactId>
    <version>1.5</version>
    <configuration>
        <driver>org.hsqldb.jdbcDriver</driver>
        <url>jdbc:hsqldb:file:${project.build.directory}/db/margarita;shutdown=true</url>
        <user>develop</user>
        <password></password>
        <schemas>margarita</schemas>
        <table>schema_history</table>
        <initialVersion>118</initialVersion>
        <initialDescription>Base Migration</initialDescription>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.hsqldb</groupId>
            <artifactId>hsqldb</artifactId>
            <version>2.2.8</version>
        </dependency>
    </dependencies>
</plugin>

当我运行这个命令时：

mvn flyway:migrate

我收到此错误消息：

这不是受支持的进程吗？我以为 hsqldb 会自动创建引用的架构，所以我很困惑。

Answer 1

您的 SQL 脚本中似乎有错误：

Caused by org.hsqldb.HsqlException: invalid schema name: MARGARITA

尝试通过从 CREATE TABLE 子句中删除模式名称来更新您的 SQL 脚本。示例：

CREATE TABLE schema_history (
version VARCHAR(20) PRIMARY KEY,
description VARCHAR(100),
...

Answer 2

尝试运行下一条命令：mvn flyway:clean flyway:init flyway:migrate 它应该工作
