Re: Checkstyle Custom rule fails to instantiate

Hi Lars,

I am running Windows 7, and have set CLASSPATH correctly(trying both \ and /
in that path!), but cannot run directly from another folder so have to use
the -JAR option and then with the full path.
This is what it all end up looking like:

C:\02-Client-Code\Client\Checkstyle>java -D64 -jar
c:/checkstyle-5.5/checkstyle-5.5-all.jar -c
"C:/02-Client-Code/Client/Checkstyle/client_checks.xml" -f
 xml -o C:/02-Client-Code/Client/Checkstyle/Client_checkstyle_errors.xml -r
"E:/Eclipse Projects/Client_Rules_Test/src"

instantiate LoggerAttr

This is very worrying as I have now tried it on three platforms and get the
same result each time.

Hello Mark,

if I got it right you need to fully specify each jar in the CLASSPATH
variable (or via -cp cmd line option) or use a classpath wildcard to pick up
all jars in a folder (e.g. foo/*).

http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html

HTH,
Lars
