I am working on a project that has many module jar files, one of which conains my main class; I am trying to write a shell script that will setup the class path and then start the application; here is my script.
#!/bin/sh
java -cp "modules/*;lib/*" com.example.Launcher
In this example, com.example.Launcher is the class that contains public static void main(String[] args)...
The issue that I am facing is that when executing my script by ./myscript I am give the output
Error: Could not find or load main class com.example.Launcher
This would be simple, there is something wrong with the classpath right?
But if directly from the command line I execute
java -cp "modules/*;lib/*" com.example.Launcher
the exact same command from the script, in the directory the script resides, everything works just fine.
Any thoughts?
side note
I am running this via CygWin
another side note
This might be an issue with sh in CygWin. I coppied this build to a CentOS machine and tried executing it, changing the ; to a : allowed for execution from the script.
The issue persists on my window machine even with the change.
a third sidenote
It would again appear that the issue is with sh in CygWin, my final solution was this:
launcher.sh will invoke java using a : in the classpath
launcher.bat will invoke java using a ; in the classpath
On Unix-like systems the seperator is a : (not a ;). Change
java -cp "modules/*;lib/*" com.example.Launcher
to
java -cp "modules/*:lib/*" com.example.Launcher
