getting the debug logs

[Dragon-Of-Dojima]

I'm trying to write a plugin to Wasabi, and when I try to use the tail command for the logs, I get an error that the modules/main/target/.... folder doesn't exist, and when I run it standard, I see:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation

How can I get a debug log? I desperately need it to get the plugin going. I want my plugin to connect to a remote server for authentication and cannot try to implement it without a proper debug logging means.

Also, when I run

java -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8180

I get

ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]
