Terminal Error?

[Nogui]

I've been trying to get Terminal to delete an old folder and replace it with a new one with folders from a different location. The folder creation goes fine, although when I try to copy the folders from the location, it gives me an error.

My code is as below, although it's only the last 4 lines that I have trouble with:

cd ~/Library/Application\ Support/
rm -rf minecraft/*
mkdir minecraft
cd ~/Library/Application\ Support/minecraft/
mkdir bin
mkdir saves
mkdir config
mkdir texturepacks
mkdir stats
mkdir resources
cd ~/Library/Application\ Support/minecraft/bin/
mkdir natives
mkdir minecraft.jar
cd ~/Library/Application\ Support/minecraft/bin/minecraft.jar/
jar xf ~/Desktop/womc/minecraft.jar
cd ~/Library/Application\ Support/minecraft/config/
jar xf ~/Desktop/womc/config.jar

I get the following error message for both minecraft.jar and config.jar:

java.io.FileNotFoundException: /Users/Minecraft/Desktop/womc/config.jar (No such file or directory)
	at java.io.FileInputStream.open(Native Method)
	at java.io.FileInputStream.<init>(FileInputStream.java:120)
	at java.io.FileInputStream.<init>(FileInputStream.java:79)
	at sun.tools.jar.Main.run(Main.java:238)
	at sun.tools.jar.Main.main(Main.java:1149)

It says that the folder does not exist, although it's in the location specified and is named correctly.

Any help is greatly appreciated.
