### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened ## Issue Report **Title:** Adding connector-cdc-mysql dependency causes SPI loading failure and affects other connectors **Environment:** - SeaTunnel: 2.3.12 - Runtime Environment: IntelliJ IDEA - Java: 1.8.0_101 **Problem Description:** After adding the `connector-cdc-mysql` dependency to the `seatunnel-engine-examples` module, it causes the SPI mechanism to fail loading. This not only affects CDC functionality but also impacts other normally working connectors (such as FakeSource, JdbcSource). **Reproduction Steps:** 1. Add dependency in `seatunnel-engine-examples/pom.xml`: ```xml <dependency> <groupId>org.apache.seatunnel</groupId> <artifactId>connector-cdc-mysql</artifactId> <version>2.3.12</version> </dependency> ``` 2. Use any simple configuration file, such as: ```hocon env { parallelism = 1 job.mode = "BATCH" } source { FakeSource { row.num = 10 schema = { fields { id = "int" name = "string" } } } } sink { Console {} } ``` 3. Build and run: ```bash mvn clean install -DskipTests -Denforcer.skip=true ``` 4. Run `SeaTunnelEngineLocalExample` **Error Message:** ``` FactoryException: Unable to create a source for identifier 'FakeSource' Caused by: NoClassDefFoundError: org/apache/seatunnel/connectors/cdc/base/source/BaseChangeStreamTableSourceFactory ``` **Complete Error Stack Trace:** ``` Exception in thread "main" org.apache.seatunnel.core.starter.exception.CommandExecuteException: SeaTunnel job executed failed at org.apache.seatunnel.core.starter.seatunnel.command.ClientExecuteCommand.execute(ClientExecuteCommand.java:228) at org.apache.seatunnel.core.starter.SeaTunnel.run(SeaTunnel.java:40) at org.apache.seatunnel.example.engine.SeaTunnelEngineLocalExample.main(SeaTunnelEngineLocalExample.java:48) Caused by: org.apache.seatunnel.api.table.factory.FactoryException: ErrorCode:[API-06], ErrorDescription:[Factory initialize failed] - Unable to create a source for identifier 'FakeSource'. at org.apache.seatunnel.api.table.factory.FactoryUtil.restoreAndPrepareSource(FactoryUtil.java:168) at org.apache.seatunnel.api.table.factory.FactoryUtil.createAndPrepareSource(FactoryUtil.java:86) at org.apache.seatunnel.engine.core.parse.MultipleTableJobConfigParser.parseSource(MultipleTableJobConfigParser.java:394) at org.apache.seatunnel.engine.core.parse.MultipleTableJobConfigParser.parse(MultipleTableJobConfigParser.java:244) at org.apache.seatunnel.engine.client.job.ClientJobExecutionEnvironment.getLogicalDag(ClientJobExecutionEnvironment.java:123) at org.apache.seatunnel.engine.client.job.ClientJobExecutionEnvironment.execute(ClientJobExecutionEnvironment.java:191) at org.apache.seatunnel.core.starter.seatunnel.command.ClientExecuteCommand.execute(ClientExecuteCommand.java:165) ... 2 more Caused by: java.lang.NoClassDefFoundError: org/apache/seatunnel/connectors/cdc/base/source/BaseChangeStreamTableSourceFactory at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:368) at java.net.URLClassLoader$1.run(URLClassLoader.java:362) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:361) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:411) at org.apache.seatunnel.engine.common.loader.SeaTunnelBaseClassLoader.loadClassWithoutExceptionHandling(SeaTunnelBaseClassLoader.java:56) at org.apache.seatunnel.engine.common.loader.SeaTunnelChildFirstClassLoader.loadClassWithoutExceptionHandling(SeaTunnelChildFirstClassLoader.java:88) at org.apache.seatunnel.engine.common.loader.SeaTunnelBaseClassLoader.loadClass(SeaTunnelBaseClassLoader.java:47) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:370) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:404) at java.util.ServiceLoader$1.next(ServiceLoader.java:480) at java.util.Iterator.forEachRemaining(Iterator.java:116) at org.apache.seatunnel.api.table.factory.FactoryUtil.discoverFactories(FactoryUtil.java:388) at org.apache.seatunnel.api.table.factory.FactoryUtil.discoverFactories(FactoryUtil.java:379) at org.apache.seatunnel.api.table.factory.FactoryUtil.discoverOptionalFactory(FactoryUtil.java:308) at org.apache.seatunnel.api.table.factory.FactoryUtil.isFallback(FactoryUtil.java:453) at org.apache.seatunnel.api.table.factory.FactoryUtil.restoreAndPrepareSource(FactoryUtil.java:105) ... 8 more Caused by: java.lang.ClassNotFoundException: org.apache.seatunnel.connectors.cdc.base.source.BaseChangeStreamTableSourceFactory at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 35 more ``` ### SeaTunnel Version 2.3.12 ### SeaTunnel Config ```conf ## SeaTunnel Config **Configuration File:** `config/application.conf` env { parallelism = 1 job.mode = "BATCH" } source { FakeSource { row.num = 10 schema = { fields { id = "int" name = "string" } } } } sink { Console {} } **Project Dependencies:** `seatunnel-engine-examples/pom.xml` <?xml version="1.0" encoding="UTF-8"?> <!-- ~ Licensed to the Apache Software Foundation (ASF) under one or more ~ contributor license agreements.
