Installed ZBot and while trying to create the jar file from com.thed.launcher.defaultziplauncher.
It seems the Jar containing the class DefaultZBotScriptLauncher is missing
For the DefaultZBotScriptLauncher class file you need to include zephyr-socket-server jar to your project classpath.
You can find this jar in <zbot_installation_dir>/lib/zephyr-socket-server.jar.
Once you open this Jar you can find the file under zephyr-socket-server-4.6.jar\com\thed\launcher.
