I typed D:\yuicompressor-2.42\build
in Path and save it (Windows XP). But when I tried executing it the command line displayed: unable to access jarfile. The same message that appear when I type an incorrect directory.
I tried executing the file in this way:
D:\wamp\www\projects\alexchen\alexchen 0.1\scripts>java -jar yuicompressor-2.4.2.jar custom.js -o custom.min.js
I tried calling the file directly and it works:
D:\wamp\www\projects\alexchen\alexchen 0.1\scripts>java -jar D:\yuicompressor-2.4.2\build\yuicompressor-2.4.2.jar custom.js -o custom.min.js
Probably you've misread the docs:
It's simple to use, as shown in the following example. Replace /path/to with the actual path to the YUI Compressor, yuicompressor-2.4.2.jar with the actual version you are using, common.js with your input filename and common.min.js with the name you want the output file to be:
java -jar /path/to/yuicompressor-2.4.2.jar common.js -o common.min.js
This means that you should specify full path to your jar file, not to put it in the Path env variable.
