Java JPADatabase不工作的jooq codegen

我在JPADatabase中使用jooq codegen时遇到问题。我已经经历了这些，并做出了相应的改变。我的项目包含子模块，实体类位于域模块中。我有一个商务模块，它依赖于域。所以我在biz模块的pom.xml中有这个构建配置

            </configuration>
        </plugin>
    </plugins>
</build>

域模块类已经生成，但插件仍然显示ClassNotFoundException。我使用的是jooq版本3.9.1。谁能告诉我我做错了什么

更新：卢卡斯·埃德尔的答案是正确的，并被接受。我自己对这个问题的回答对我有用，因为我在maven repo中缓存了这个特定的版本。我的答案是错误的。

您似乎遇到了问题，该问题已在jOOQ 3.10中修复，并计划在3.9.3和3.8.8中解决

现在最好的解决方法可能是使用jooq meta extensions依赖项的GitHub版本（3.10-SNAPSHOT），或者相应地修补您的版本。

根据@Lukas Eder的回答，我尝试了来自的建议。以下构建配置可以工作

             <!--

              In my case, it is in the same module as the build profile is present.
              Hence the version is ${project.version}

这种配置的奇怪之处在于，我将模块作为依赖项包含在它自己的POM的构建概要中的插件中

您是否将实体放在使用jOOQ代码生成器的模块的依赖项中？见：是的。域模块是发生代码生成的biz模块中的一个依赖项。如果我降级到3.8.0会有帮助吗？@yaswanth:不会，为什么？这不是倒退。自从第一次实现以来，

JPADatabase

就一直存在这个问题。我认为类加载器问题是在以后的版本中开始出现的一个错误。@yaswanth:Hmm，不确定-最近才有报道。我怀疑，旧版本也会受到影响，但这还没有经过测试。我只是好奇。无论如何，我为这个问题写的另一个答案是有效的。你认为现在这是一个更好的解决方案吗？我的意思是问这会不会有副作用。
