java command line compilation

I have a simple, single file java program that relies on a single static jar. The java code and the jar reside in the same directory. For this one-off solution I don't want to bring in the weight of ant or maven, and just want to compile it directly.

On my dev box, the following compiles and runs my code fine:

javac -cp ".;dependency.jar" File.java
java -cp ".;dependency.jar" File

However, on my test box, the java command fails, and I get the following output:

Error: Could not find or load main class File

If I change my classpath arg to -cp "." I get the following output:

Exception in thread "main" java.lang.ClassNotFoundException: dependency

My dev box is 64-bit Windows/Cygwin and java version 1.7.0_55. My test box is 64-bit Linux and java version 1.7.0_45.

What is going wrong on my test box?

The classpath separator character is different on Linux (and on Unix) than it is on Windows. It's ; on Windows, but it's : on Linux (and Unix).

Try this on Linux:

javac -cp ".:dependency.jar" File.java
java -cp ".:dependency.jar" File
