Please, use the new JIRA for project is on https://ec.europa.eu/digital-building-blocks/tracker/projects/DSS/issues.

The latest version of DSS framework has the following minimal requirements:

• Java 11 and higher (tested up to Java 18) for the build is required. For usage Java 8 is a minimum requirement;
• Maven 3.6 and higher;
• Memory and Disk: see minimal requirements for the used JVM. In general the higher available is better;
• Operating system: no specific requirements (tested on Windows and Linux).

The release is published on Maven Central repository :

A simple build of the DSS Maven project can be done with the following command:

mvn clean install

This installation will run all unit tests present in the modules, which can take more than one hour to do the complete build.

In addition to the general build, the framework provides a list of custom profiles, allowing a customized behavior:

• quick - disables unit tests and java-doc validation, in order to process the build as quick as possible (takes 1-2 minutes). This profile cannot be used for a primary DSS build (see below).
• quick-init - is similar to the quick profile. Disables java-doc validation for all modules and unit tests excluding some modules which have dependencies on their test classes. Can be used for the primary build of DSS.
• slow-tests - executes all tests, including time-consuming unit tests.
• owasp - runs validation of the project and using dependencies according to the National Vulnerability Database (NVD).
• jdk19-plus - executed automatically for JDK version 9 and higher. Provides a support of JDK 8 with newer versions.
• spotless - used to add a licence header into project files.

In order to run a build with a specific profile, the following command must be executed:

mvn clean install -P *profile_name*

The documentation and samples are available in the dss-cookbook module. SoapUI project and Postman project are also provided to illustrate SOAP/REST calls.

In order to build the documentation by yourself, the following command must be executed in dss-cookbook module:

mvn clean install -P asciidoctor
