添加Email连接器后出现Unknown mediator错误的技术咨询

按照WSO2官方Gmail连接器教程操作，向序列中添加Email连接器后，执行Export Artifacts并运行应用时出现如下错误：

[2023-11-10 10:52:27,928] ERROR {MediatorFactoryFinder} - Unknown mediator referenced by configuration element : {http://ws.apache.org/ns/synapse}email
[2023-11-10 10:52:27,928] ERROR {SequenceDeployer} - Sequence Deployment from the file : C:\IntegrationStudio\runtime\microesb\tmp\carbonapps\-1234\1699609947789TestCompositeApplication_1.0.0.car\PaymentRequestProcessingSequence_1.0.0\PaymentRequestProcessingSequence-1.0.0.xml : Failed. org.apache.synapse.SynapseException: Unknown mediator referenced by configuration element : {http://ws.apache.org/ns/synapse}email
    at org.apache.synapse.config.xml.MediatorFactoryFinder.getMediator(MediatorFactoryFinder.java:246)

已尝试的排查操作：

• 重新从头执行教程步骤
• 检查SampleServicesCompositeExporter pom.xml中是否加载了所有必要依赖
