Maven pom.xml文件中的JOOQ插件

我正在尝试构建官方JOOQ git repo here上给出的示例。行家pom.xml文件包含JOOQ以下插件：Maven pom.xml文件中的JOOQ插件

<plugin> 
 
    <groupId>org.jooq</groupId> 
 
    <artifactId>jooq-codegen-maven</artifactId> 
 
    <version>${org.jooq.version}</version> 
 
    <executions> 
 
     <execution> 
 
      <phase>generate-sources</phase> 
 
      <goals> 
 
       <goal>generate</goal> 
 
      </goals> 
 
      <configuration> 
 
       <jdbc> 
 
        <driver>${db.driver}</driver> 
 
        <url>${db.url}</url> 
 
        <user>${db.username}</user> 
 
        <password>${db.password}</password> 
 
       </jdbc> 
 
       <generator> 
 
        <target> 
 
         <packageName>com.learnd.jooq.db</packageName> 
 
         <directory>src/main/java</directory> 
 
        </target> 
 
       </generator> 
 
      </configuration> 
 
     </execution> 
 
    </executions> 
 
</plugin>

但是我不设法mvn compile，项目，和我越来越因为${org.jooq.version}变量以下输出<version>标签。但是每当我看到插入这个插件时，我都会看到这样做，即使是here。

任何人都可以帮助我吗？干杯。

它很可能是因为Maven无法在您的本地.m2中找到jOOQ-codegen-maven 3.10.0-SNAPSHOT版本。我检查了你的问题的链接，我在这个链接https://github.com/jOOQ/jOOQ/blob/master/jOOQ-codegen-maven/pom.xml中看到了spring项目及其依赖项目jOOQ-codegen-maven，因此导入并构建它，以便该版本进入本地.m2。我看到jOOQ-codegen-maven项目有一个父jooq-parent，所以你可能需要构建它，以便依赖关系得到解决。

成功构建并运行jOOQ-codegen-maven和jooq-parent后，您的本地.m2应该具有这些依赖关系，请尝试再次构建jooq-spring-example，现在需要解析3.10.0-SNAPSHOT依赖关系正常。

上面应该很有可能解决问题，但如果它不起作用，你可以尝试使用中央版本https://mvnrepository.com/artifact/org.jooq/jooq-codegen-maven/3.9.5，看看是否有助于构建你的春天的例子。
