Building BASE from source code

1. Getting the source code


The source code for most BASE releases can be downloaded from the DownloadPage. The code is packaged in a compressed TAR archive. Unpack this to a directory of your choice.


The BASE source code lives in a Subversion server. It is a versioning system that enables us to keep track of all changes made to the code. You will need a client for subversion to be able to get the source code. If you are using Eclipse there is an excellent subversion plugin.

Check out the source code with the command:

svn checkout base-src

This will create a sub-directory base-src with all source files. Anonymous checkouts are allowed, but write permission is only granted to developers. The trunk version is the head of the development and should be used for testing purposes only. The sub-urls to* and* can be used to get other version, including specific releases and bugfix branches. For more information see the DownloadPage or check the subversion source repository directly.

2. Create a local configuration

The configuration files included with a binary distribution are located in the <base-src>/config/dist directory. You should never modify these files directly for your local setup. Instead, place a copy of files that you need to modify in the <base-src>/config/local directory. When building BASE all targets exception the 'dist' target will first check the local configuration files.

Note that the build process usually copies the configuration files to the <base-src>/www/WEB-INF/classes directory. The reason is that Tomcat can't read files outside the WEB-INF directory and this makes the subversion working copy identical to a binary distribution.

  • All utility programs, such as the installation program and the job agent, use the configuration files in <base-src>/www/WEB-INF/classes.
  • The only exception is the test programs. They will read the configuration from <base-src>/config/local and <base-src>/config/dist directories.
  • Running ant clean will remove the copied configuration files.

3. Ant

We use Ant to build and compile BASE. We recommend Ant 1.10. All build instructions for Ant are in the build.xml file.

A build is started with the command:

ant <target>

where <target> is one of the named targets defined in the build file. You may specify multiple targets:

ant web jobagent

All <property>:s defined in build.xml can be overridden by creating a file and adding white-space separated key-value pairs with new property values. It is, for example, needed to set tomcat.home to the path to a Tomcat installation in order to check that JSP file compile. See below and #2151 for more information.

Main build targets

These targets works on the entire BASE source code. They may take some time to finish, but everything will be checked and recompiled if needed.

ant dev

Build everything for local use. This targets compiles the core, plugins, web application, job agent, etc. for local use. It doesn't generate javadoc documentation.

ant dist

Build everything for distribution. This target compiles everything, generates the javadoc documentation, etc. Everything is placed in the dist subdirectory.

ant package

Create compressed tar files of the distribution.

ant clean

Remove all generated files.

Other useful targets

These targets are quicker to use if you know that you have only made changes to a specific module.

ant core

Compile the core for local use.

ant coreplugins

Compile the core plugins for local use.

ant web

Compile the web client application for local use.

ant installprg

Compile the installation programs for local use.

ant jobagent

Compile the job agent for local use.

ant test

Compile the test programs for local use.

ant doc

Generate documentation for local use. This generates all documentation and may take a long time.

ant doc.javadoc

Generate Javadoc documentation only. The documentation is generated in the <base-src>/doc/api directory.

ant doc.docbook.html

Generate user- and administrator documentation from docbook in HTML format. Docbook will work with pure Java but performance is better if XSLTPROC is installed. The documentation is generated in the <base-src>/doc/html directory.

Pre-compiling JSP pages

This should be performed at regular intervals and at least before a new minor release. You need to have Tomcat installation that includes the build tools. If the ${tomcat.home}/bin/catalina-tasks.xml file is present then you have the correct version. If not, we recommend that the ZIP distribution is downloaded and unpacked to some place. It can be anywhere, you will not have to run an actual Tomcat instance from there.

Create a file in your root BASE development directory (=same directory where build.xml is located). Add a tomcat.home entry that points to the directory where the Tomcat installation is located. The JSP files can then compiled by:

ant jsp

The goal is that this should compile without errors or warnings. Warnings can be controlled by the Xlint parameter. It is by default set to Xlint:all,-serial. The -serial option is needed since Jasper doesn't create serialVersionUID fields in the generated code. The Xlint parameter can be customized by setting the jsp.xlint property in the file (only the part after Xlint:). For example:

jsp.xlint all,-serial,-unchecked,-rawtypes,-deprecation,-cast

Running BASE from the local installation

If you have followed the instructions so far the subversion working copy installation is compatible with a binary distribution. You can find the installation programs, web application and all other things in the same places as for a binary installation. Read the installation instructions for more information.
