如何在camunda上启用CustomRetryHandler

Question

在tomcat上启动Camunda7.7版时，我们使用的文件是这样的https://github.com/camunda/camunda-bpm-platform/blob/master/distro/tomcat/assembly/src/conf/bpm-platform.xml

如何启用CustomRetryHandler？

我发现如果我们使用7.8版本，默认情况下它是启用的。但我们现在是7.7版本，现在还没有升级的计划。

我找到了这个页面。https://forum.camunda.org/t/custom-retry-configuration-in-camunda-wildlfy-subsystem/5345

但如果我尝试添加

<property name="customPostBPMNParseListeners">
                          org.camunda.bpm.engine.impl.bpmn.parser.FoxFailedJobParseListener
                    </property>
                    <property name="failedJobCommandFactory">
                          org.camunda.bpm.engine.impl.jobexecutor.FoxFailedJobCommandFactory
                    </property>

我得到了这个错误

希望有人能给我贴上正确的方向=)

默认情况下处于启用状态。因此不需要进行任何更改。

我想当你使用部署描述符的时候会有所不同。
