Cygwin : error: package net.jradius.packet.attribute does not exist - cygwin

Question

This doesn't appear to be the usual CLASSPATH issue, but maybe something specific to cygwin.
The following illustrates the issue.
import net.jradius.packet.attribute.AttributeFactory;
public class Test{
static int x = 100;
}
When compiling the following error appears.
$ javac Test.java
Test.java:1: error: package net.jradius.packet.attribute does not exist
import net.jradius.packet.attribute.AttributeFactory;
^

The file jradius-core-1.1.4.jar is in the CLASSPATH.
When using the command line within Windows it works. Here is the classpath.
set CLASSPATH=c:\Temp\jradius-core-1.1.4.jar
When using cygwin it produces the error. Here is the classpath.
export CLASSPATH=/cygdrive/c/Temp/jradius-core-1.1.4.jar
The location is valid via cygwin as the following shows it is recognized.
ls $CLASSPATH
/cygdrive/c/Temp/jradius-core-1.1.4.jar
The same JDK is used for both scenarios.
Any idea why it may be failing via cygwin???

Answer 1

You are using JDK built for windows, so the environment is for windows.
That's being said, you should be provide windows-style path to javac.
cygpath is what you are looking for here.
Try:
javac Test.java -cp `cygpath.exe -w /cygdrive/c/Temp/jradius-core-1.1.4.jar`
cygpath -w means print in windows style.
Or just put the jar file in the same directory of the java file, and in cygwin:
javac Test.java -cp jradius-core-1.1.4.jar
Refer from this

Answer 2

Added the JAR files into the directory and changed the classpath to include '*' and that appears to have worked.
