Welcome to the source code of BaseX.

To get the project running as smooth as possible, please consider the following notes:

Compiling BaseX

JDK 1.6 and JUnit is currently required to compile the complete sources of the main project. If you are using another environment than Eclipse or don't have JUnit installed, just delete the test packages inside the project and rebuild the project.

Please take a look at the Maven documentation for information on how to use Maven.

You can launch the following classes, which are all placed in the basex-core directory and the org.basex main package:

BaseX        : console mode
BaseXServer  : server instance, waiting for requests
BaseXClient  : console mode, interacting with the server
BaseXGUI     : graphical user interface

Moreover, try -h to list the available command line options. For example, you can use BaseX to process XQuery expressions without entering the console.
