爲什麼Maven Flyway插件無法遷移我的Hsqldb數據庫？

Question

我在使用flyway和maven插件初始化和遷移HSQLDB數據庫時遇到了問題。

我有XML的此塊在我的pom.xml：

<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> 

當我運行此命令：

mvn flyway:migrate 

我收到此錯誤信息：

是這不是一個支持的過程？我認爲hsqldb會自動創建引用的模式，所以我很困惑。

Answer 1

看來，你在你的SQL腳本有一個錯誤：

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

嘗試從CREATE TABLE條款刪除模式名稱更新你的SQL腳本。例如：

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

嘗試運行下一個命令：在`CREATE TABLE瑪格麗塔前http://flywaydb.org/documentation/maven/
