Maven pom.xml文件中的JOOQ插件

我正在嘗試構建官方JOOQ git repo here上給出的示例。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>

但是我不設法mvn compile，項目，和我越來越因爲${org.jooq.version}變量以下輸出<version>標籤。但是每當我看到插入這個插件時，我都會看到這樣做，即使是here。

任何人都可以幫助我嗎？乾杯。

它很可能是因爲Maven無法在您的本地.m2中找到jOOQ-codegen-maven 3.10.0-SNAPSHOT版本。我檢查了你的問題的鏈接，我在這個鏈接https://github.com/jOOQ/jOOQ/blob/master/jOOQ-codegen-maven/pom.xml中看到了spring項目及其依賴項目jOOQ-codegen-maven，因此導入並構建它，以便該版本進入本地.m2。我看到jOOQ-codegen-maven項目有一個父jooq-parent，所以你可能需要構建它，以便依賴關係得到解決。

成功構建並運行jOOQ-codegen-maven和jooq-parent後，您的本地.m2應該具有這些依賴關係，請嘗試再次構建jooq-spring-example，現在需要解析3.10.0-SNAPSHOT依賴關係正常。

上面應該很有可能解決問題，但如果它不起作用，你可以嘗試使用中央版本https://mvnrepository.com/artifact/org.jooq/jooq-codegen-maven/3.9.5，看看是否有助於構建你的春天的例子。
