我正在尝试在Scala中为keycloak实现一个事件侦听器，我将其用作胖子，但是当我添加kryo序列化时，我得到了ClassNotFoundException
现在，我将项目从sbt移到了maven，以便按照beercloak示例的结构制作一个ear，已经部署了事件侦听器，但是我不确定如何将Scala库包含在依赖项中。
这是我的jboss-deployment-structure：
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<module-alias name="deployment.keycloak-listener"/>
</deployment>
<sub-deployment name="keycloak-listener.jar">
<dependencies>
<!--<module name="org.scala-lang-scala-library"/>-->
<!--<module name="org.scala-lang"/>-->
<!-- I don't know how to add scala library -->
</dependencies>
</sub-deployment>
</jboss-deployment-structure>
这是我的ear的结构：
