Environment

Linux

EventMesh version

master

What happened

1. After gradle dist & zip , there is no pulsar connector in dir:./plugin/connector , so as other connectors(pravega,knative.etc)
2. set connector.plugin.type=pulsar And start runtime, Can't start connector with exception:

Caused by: java.lang.ClassNotFoundException: org.apache.eventmesh.connector.rocketmq.producer.PulsarProducerImpl
at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[?:1.8.0_161]

... 16 more

It is caused by the wrong spi settings in the gradle.properties and META-INF.eventmesh for EventMesh-connector-plugin

Should't use rocketmq tag in pulsar connector .

How to reproduce

1. ./gradlew clean dist
2. ./gradlew installPlugin
3. bash dist/bin/start.sh //mv pulsar connector to plugin
4. see dist/logs/eventmesh.out

Hi @fengyongshe,

Thanks for your question. I reproduced according to the above four steps but did not find the class loading bug for Knative and Pravega connectors. Knative and Pravega connector plugins can be installed in dist/plugin folder after ./gradlew installPlugin and the EventMesh server can be started fine after bash dist/bin/start.sh.

The class loading configuration for the Pulsar connector is in development. I think you can feel free to submit a PR to help fix the related configuration files.
