JasperReports Server身份验证：找不到类

Question

我想将身份验证Oauth2.0与jasper服务器v7.1.1一起使用

遵循以下配置： https://community.jaspersoft.com/wiki/configuring-oauth-20-tibco-jasperreports-server-v61#Oauth_External_Authentication_Setup

但是我有一个错误：

org.springframework.beans.factory.CannotLoadBeanClassException: Cannot
find class[com.jaspersoft.jasperserver.multipleTenancy.security.externalAuth.processors.MTExternalTenantSetupProcessor]
for bean with name 'externalTenantSetupProcessor' defined in
ServletContext resource
[/WEB-INF/applicationContext-externalAuth-oAuth.xml]; nested exception
is java.lang.ClassNotFoundException:
 com.jaspersoft.jasperserver.multipleTenancy.security.externalAuth.processors.MTExternalTenantSetupProcessor

如何解决此错误？
