[FIX] XQuery, GH-1424: Fixes Closure copying.


Welcome to the source code of BaseX.

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

Compiling BaseX

JDK 1.7 and JUnit are 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.

Using Eclipse

BaseX is being developed with the Eclipse environment. Some style guidelines are integrated in the sources of BaseX; they are being embedded as soon as you open the project.

Running BaseX

The following steps can be performed to start BaseX with Eclipse:

  • Press Run -> Run...
  • Create a new Java Application launch configuration
  • Select basex as Project
  • Choose a Main class (e.g., org.basex.BaseXGUI)
  • Launch the project via Run

Adding Checkstyle

Some additional Checkstyle guidelines are defined in the project:

  • Open Eclipse
  • Press Help -> Install new Software...
  • Press Search for new features to install
  • Enter the URL:
  • Follow the installation procedure and restart Eclipse

Using Git

The code base of BaseX can be accessed via GitHub.

Docker Image

The BaseX server is also available as automated build basex/basexhttp on the Docker Hub, providing both release and nightly builds. All images are automatically rebuild if Docker provides updated base images.

To start a BaseX container based on the latest development release publishing the BaseX server and HTTP ports 1984 and 8984 and bind-mounting your user's BaseXData directory, run

docker run -ti \
    --name basexhttp \
    --publish 1984:1984 \
    --publish 8984:8984 \
    --volume ~/BaseXData:/srv/BaseXData \

By passing any other BaseX executable, you can also for example run a BaseX client connecting to the linked BaseX server for management operations on the BaseX command line:

docker run -ti \
    --link basexhttp:basexhttp \
    basex/basexhttp:latest basexclient -nbasexhttp

If you prefer the DBA web interface, this can also be linked against your server container:

docker run -d \
    --name basex-dba \
    --publish 18984:8984 \
    --link basexhttp:basexhttp \

If you want to add your own application, create an image FROM basex/basexhttp:[tag] with [tag] being the BaseX version you're developing against. Usually, you will add your application code to /srv/BaseXWeb and modules to /srv/BaseXRepo. BaseXData is persisted as a volume, which means it cannot be preinitialized in the application image.

For further information on using the Docker image, refer to the BaseX Docker documentation.
