Build and usage

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

mvn clean install

These 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 check, in order to process the build as quick as possible (takes 2-3 minutes). Be aware, that some modules (dss-test, dss-utils, dss-crl-parser and dss-pades) still have to be built completely.
  • 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
