java - 乔克 : Generate sources with maven in Eclipse is not generating any file

Question

我是 JOOQ 和 Maven 的新手。我想通过提供模式来生成 Pojo，如 JOOQ 的文档所述。我尝试使用命令行方式，它运行得很好。我在 Eclipse java 项目中添加了相同的配置。下面是我的 pom.mxl

我尝试生成资源。它说“BUILD SUCCESS”，但我在任何地方都看不到生成的 Pojo。请让我知道我缺少什么。

您仍然需要将该插件添加到您的构建中，如 <pluginManagement>仅帮助您声明通用配置以供重用。

<build>
    <pluginManagement>...</pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.jooq</groupId>
            <artifactId>jooq-codegen-maven</artifactId>
            <execution>...</execution>
        </plugin>
    </plugins>
</build>

另请参阅此处的问题:Maven: What is pluginManagement?

在这种情况下，可能更简单的是 ignore this well-known issue in Eclipse and avoid the <pluginManagement> element .
