Liquibase简单更改日志NullPointerException

标签： liquibase

我使用Liquibase进行了简单的迁移设置。不幸的是，当我尝试addColumn时，它会导致NullPointerException。 （创建表工作正常）。

// File structure
pom.xml
  src/main/resources/liquibase/
    db.changelog.xml
    liquibase.properties
    changesets/
      simple.changeset.xml


// pom.xml
<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>${liquibase.version}</version>
    <configuration>
        <propertyFile>src/main/resources/liquibase/liquibase.properties</propertyFile>
        <changeLogFile>src/main/resources/liquibase/db.changelog.xml</changeLogFile>
        <promptOnNonLocalDatabase>false</promptOnNonLocalDatabase>
    </configuration>
</plugin>

// simple.changeset.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-3.2.xsd">
    <changeSet id="1517019028" author="me">
        <createTable tableName="test">
            <column name="test_field_1" type="varchar(255)"></column>
        </createTable>
        <addColumn tableName="test">
            <column name="test_field_2" type="varchar(255)"></column>
        </addColumn>
    </changeSet>
</databaseChangeLog>

createTable命令成功，但addColumn命令总是失败。运行mvn clean package liquibase:update会生成以下错误：

之前有人遇到过这个问题吗？从我从文档中可以看出，我的设置相当典型但我在网上找不到任何类似的问题。

以下是我为展示问题而创建的示例回购：https://github.com/cha55son/liquibase-add-column-bug

答案 0 :(得分：0)

这可能是针对SQLite的liquibase驱动程序的错误。

如果是这种情况，您可能希望切换到另一个数据库。

或者，您可以尝试在更改集中使用原始SQL（基于您的github代码）：

    <changeSet id="2" author="me">
        <sql>
            ALTER TABLE TEST ADD COLUMN TEST_FIELD varchar(255)
        </sql>
    </changeSet>
