### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues.
### What happened
This error is reported when the latest dev code is packaged and executed to start the cluster
After modifying the seatunnel-cluster.sh script, it can be executed
If the startup script is not annotated, execute it，
```
# while read line
# do
# if [[ ! $line == \#* ]] && [ -n "$line" ]; then
# JAVA_OPTS="$JAVA_OPTS $line"
# fi
# done < ${APP_DIR}/config/jvm_options
```
启动脚本注释上面的shell命令就可以启动集群，但是加上就不能执行启动集群

目前的原因就是 在win打包字符编码问题导致的，必须在linux下打包编译才可以

> Can you provide the complete JAVA_OPTS?
`JAVA_OPTS: -Dseatunnel.config=/home/hadoop/apache-seatunnel-incubating-2.3.2-SNAPSHOT/config/seatunnel.yaml -Dhazelcast.config=/home/hadoop/apache-seatunnel-incubating-2.3.2-SNAPSHOT/config/hazelcast.yaml -Dlog4j2.contextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector -Dlog4j2.configurationFile=/home/hadoop/apache-seatunnel-incubating-2.3.2-SNAPSHOT/config/log4j2.properties -Dseatunnel.logs.path=/home/hadoop/apache- -XX:+HeapDumpOnOutOfMemoryErrorrcent=30 -Dseatunnel.logs.file_name=seatunnel-engine-server
这个是shell打印的执行命令，如果单独拷贝出来执行，正常启动集群，如果在seatunnel-cluster.sh脚本里执行，就报错
