alessandromonguzzi opened a new issue #259: URL: https://github.com/apache/camel-kafka-connector/issues/259
Download camel-elasticsearch-rest-kafka-connector from https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-elasticsearch-rest-kafka-connector/0.2.0/camel-elasticsearch-rest-kafka-connector-0.2.0-package.zip The log4j2 dependencies are missing and they cause NoClassDefFoundError when the connector is used. To reproduce it with Strimzi follow these steps: 1. Start Kafka broker cluster 2. Start KafkaConnectS2I cluster 3. Prepare the connector plugin and start a new KafkaConnectS2I build: ``` mkdir connectors curl https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-elasticsearch-rest-kafka-connector/0.2.0/camel-elasticsearch-rest-kafka-connector-0.2.0-package.zip > connectors/file.zip unzip -d connectors file.zip rm connectors/file.zip oc start-build my-connect-cluster-connect --from-dir=./connectors --follow ``` Similar things can be done on local installation. When the connector is firstly invoked, the following error occurs: ``` Caused by: java.lang.NoClassDefFoundError: org/apache/logging/log4j/LogManager at org.elasticsearch.rest.BytesRestResponse.<clinit>(BytesRestResponse.java:120) at org.elasticsearch.client.RestHighLevelClient.parseEntity(RestHighLevelClient.java:1727) at org.elasticsearch.client.RestHighLevelClient.parseResponseException(RestHighLevelClient.java:1704) at org.elasticsearch.client.RestHighLevelClient.internalPerformRequest(RestHighLevelClient.java:1467) at org.elasticsearch.client.RestHighLevelClient.performRequest(RestHighLevelClient.java:1424) at org.elasticsearch.client.RestHighLevelClient.performRequestAndParseEntity(RestHighLevelClient.java:1394) at org.elasticsearch.client.RestHighLevelClient.index(RestHighLevelClient.java:836) at org.apache.camel.component.elasticsearch.ElasticsearchProducer.process(ElasticsearchProducer.java:169) at org.apache.camel.support.AsyncProcessorConverterHelper$ProcessorToAsyncProcessorBridge.process(AsyncProcessorConverterHelper.java:67) ... 28 more Caused by: java.lang.ClassNotFoundException: org.apache.logging.log4j.LogManager at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:418) at org.apache.kafka.connect.runtime.isolation.PluginClassLoader.loadClass(PluginClassLoader.java:104) at java.lang.ClassLoader.loadClass(ClassLoader.java:351) ... 37 more ``` In attach the full log file: [my-connect-cluster-connect-2-cc4nf-my-connect-cluster-connect.log](https://github.com/apache/camel-kafka-connector/files/4746196/my-connect-cluster-connect-2-cc4nf-my-connect-cluster-connect.log) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
