Need intuition on Apache Console Filter

I am a java noob , developing a plugin that requires the use vanilla commands , how can I filter those message containing a certain string to the log.

I heard that theres a apache filter that can do it , serched it on google amd i dont understand those posts , can anyone give me some intuition on how to use it ?

Dont tell me to use another plugin cuz i wanna incoporate it into the same thing

 

Teleported Minecart to x y z

 

yes, but like there is quite a bit of code before that.......

cart.teleport does NOT work , it does not teleport the player in it

if you wanna to displace players between different minecarts, i have tested it and the experience is not smooth

this is what i used

or is there any way to teleport the cart AND THE PLAYER inside the cart

 

yes, but like i need to place the command block in world

 

but different minecarts have different teleportation speed?

 

it doesnt really work , cuz there maybe different minecart running at the same time , also , not many server are willing to do so cuz the command block need to be chunkload and those stuff

like , anyway, how to use a log4j filter

Like i dont really understand all those codes, like its so different from what i was working on , would you mind telling me exactly what to change? (a.k.a from what to what)

I want this to disappear
