Vscode start SeaTunnelEngineLocalExample failed, Help Needed

1、using .vscode/launch.json, start debug, lots of compile error.
{
"version": "0.2.0",
"configurations": [
{
"type": "java",
"name": "Debug SeaTunnelEngineLocalExample",
"request": "launch",
"mainClass": "org.apache.seatunnel.example.engine.SeaTunnelEngineLocalExample",
"cwd": "${workspaceFolder}",
"console": "internalConsole"
}
]
}

**2、using mvn to run, I got "Unable to create a source for identifier 'MySQL-CDC'." error.**
mvn -pl seatunnel-examples/seatunnel-engine-examples exec:java -Dexec.mainClass="org.apache.seatunnel.example.engine.SeaTunnelEngineLocalExample"

env {
parallelism = 1
job.mode = "STREAMING"
checkpoint.interval = 10000
}

source {
MySQL-CDC {
plugin_output = "mysql-cdc"
base-url = "jdbc:mysql://127.0.0.1:3306/test"
username = "root"
password = "123456"
table-names = ["test.user"]

startup.mode = "initial"
}
}

transform {
}
sink {
Console {
plugin_input = "mysql-cdc"
}
}

I got "Unable to create a source for identifier 'MySQL-CDC'." error.
I have put plugins in lib 、connectors、plugins directory.

Start with seatunnel-examples/seatunnel-engine-examples and the SeaTunnelEngineLocalExample.main stack trace, then inspect FactoryUtil and MySqlIncrementalSourceFactory around source creation. Reproduce both the VS Code launch and the Maven exec command, checking the reported compile and JDBC errors. Done means the local example starts and the MySQL-CDC source initializes successfully.
