Question

我正在测试将JOOQ从3.9升级到3.11.2。它在编译时失败，并在Maven中抛出以下错误跟踪：

Error running jOOQ code generation tool: Error generating code for catalog: Error generating code for schema XXX: NullPointerException

我更改了maven配置中某些元素的软件包名称。模式（XXX）的名称为大写，这是配置：

<generator>
    <name>org.jooq.codegen.JavaGenerator</name>
    <strategy>
        <name>org.jooq.codegen.DefaultGeneratorStrategy</name>
    </strategy>
    <database>
        <name>org.jooq.meta.oracle.OracleDatabase</name>
        <includes>
           Tables and procedures...
        </includes>
        <includeExcludeColumns>true</includeExcludeColumns>
        <inputSchema>XXX</inputSchema>
        <forcedTypes>
            <forcedType>
                <name>VARCHAR2</name>
                <types>NUMBER</types>
            </forcedType>
            <forcedType>
                <name>VARCHAR2</name>
                <types>DATE</types>
            </forcedType>
        </forcedTypes>
    </database>
    <generate>
        <relations>true</relations>
        <daos>false</daos>
        <pojos>true</pojos>
        <records>true</records>
        <globalObjectReferences>true</globalObjectReferences>
        <fluentSetters>false</fluentSetters>
    </generate>
    <target>
        <packageName>com.model</packageName>
        <directory>src/main/java</directory>
    </target>
</generator>

有人可以帮我吗？

预先感谢

这绝对是一个错误： https://github.com/jOOQ/jOOQ/issues/7824

它与先前将jOOQ引入索引的错误类似：https://github.com/jOOQ/jOOQ/issues/6620

似乎Oracle集成仍然受到影响。您可以放心地忽略堆栈跟踪，因为它不会对代码生成产生任何影响，也可以使用以下命令关闭索引信息的生成：

<generator>
    ...
    <database>
        ...
        <includeIndexes>false</includeIndexes>
    </database>
    ...
</generator>

为架构生成代码时出错，升级Jooq 3.11
