Jooq 自定义代码生成器策略的类路径问题

Question

我正在尝试使用自定义代码生成器策略运行 Jooq 代码生成。使用匹配器规则是有效的，但对于我的情况来说太有限了。代码生成由 Maven 调用，其配置嵌入在 POM 中，自定义策略的源代码也是如此：

如何使 codegen 包可用于我的自定义策略？

不确定为什么传递依赖项不可用于您的插件执行，但您始终可以将它们明确地放在插件类路径中，即：

<plugin>

    <!-- .. -->
    <dependencies>
        <dependency>
            <groupId>org.jooq</groupId>
            <artifactId>jooq-meta</artifactId>
            <version>${jooq.version}</version>
        </dependency>
        <dependency>
            <groupId>org.jooq</groupId>
            <artifactId>jooq-codegen</artifactId>
            <version>${jooq.version}</version>
        </dependency>
    </dependencies>
</plugin>
