Keycloak 向JWT添加声明的KeyClope协议映射程序获取空指针异常

我很难得到一个在Keyclope 6.0.1中工作的非常简单的Keyclope协议映射程序。
我正在尝试向访问令牌添加额外声明。当我将构建的jar复制到部署目录时，我在部署目录中得到以下NullPointerException，在.failed文件中包含以下内容

{"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"token-enhancer-1.0-SNAPSHOT.jar\".POST_MODULE" => "WFLYSRV0153: Failed to process phase POST_MODULE of deployment \"token-enhancer-1.0-SNAPSHOT.jar\"
    Caused by: java.lang.NullPointerException"}}

下面的日志显示了相同的异常

我已将示例代码上载到

我有一个艰难的时间，因为我不明白在哪里解决这样一个模糊的错误信息。调查这个问题的好策略是什么

尝试在类的顶部添加

包
语句（
keydovetokenhancer
），并将类移动到包中

NPE从以下位置抛出：

String packageName=factory.getClass（）.getPackage（）.getName（）；

另见：

返回：

类的包，如果存档或代码库中没有可用的包信息，则为null

你的回答让我找到了一个更好的解决问题的方法。我现在觉得很傻。非常感谢。
