Cannot run logstach 8.1.0 with the command - logstash

Question

I have a problem about running defined configuration file in logstash though its command.
Here is my conf file shown below.
input {
file {
type => "userslog"
path => "C:\Users\aaa\Downloads\logstash-8.1.0\users-ms.log"
}
file {
type => "albumslog"
path => "C:\Users\aaa\Downloads\logstash-8.1.0\albums-ms.log"
}
}
output {
if[type]=="userslog"{
elasticsearch {
hosts => ["localhost:9200"]
index => "userslog-%{+YYYY.MM.dd}"
}
} else if[type]=="albumslog"{
elasticsearch {
hosts => ["localhost:9200"]
index => "albumslog-%{+YYYY.MM.dd}"
}
}
stdout {codec => rubydebug}
}
Here is the result shown below.
C:\Users\aaa\Desktop\logstash-8.1.0\bin>logstash logstash-simple.conf
"Using bundled JDK: ."
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
[FATAL] 2022-03-17 12:03:32.267 [main] Logstash - Logstash stopped processing because of an error: (NameError) missing class name (`org.apache.http.─▒mpl.client.StandardHttpRequestRetryHandler')
org.jruby.exceptions.NameError: (NameError) missing class name (`org.apache.http.─▒mpl.client.StandardHttpRequestRetryHandler')
When changed 'Java::OrgApacheHttpImplClient::StandardHttpRequestRetryHandler' to 'Java::OrgApacheHttp.impl.client::StandardHttpRequestRetryHandler', it didn't work.
How can I fix it?
