Question

I’m having much difficulty running my jar file, probably because I’m not sure the proper syntaxes to use when using various switches on the commandline. Here’s what I have:

java -classpath %appdata%\.minecraft\bin\minecraft.jar;%appdata%\.minecraft\bin\mp3spi.jar;%appdata%\.minecraft\bin\jl.jar;%appdata%\.minecraft\bin\tritonus.jar;%appdata%\.minecraft\bin\lwjgl.jar; net.minecraft.client.Minecraft username password server.com:25565 -D java.library.path=%appdata%\.minecraft\bin\lwjgl.jar

I need to have all of those things included in my classpath, and also set -D to the value I have.

Can someone help me identify the problem? Thanks 🙂

Answer 1

Put your options (classpath with -classpath, system properties with -D) first, then your class (net.minecraft.client.Minecraft), finally the class arguments (username, password, …).

Also, it’s -Dproperty=value, with no blank separating the -D and your setting.
Finally, java.library.path points to a directory, not a file.

Here’s the doc.
