Java Setup Procedure for Windows

In Winodws’ Control Panel \ System \ Advanced \ Environment Variables define the global variable:


Note that the \Program Files directory is referred using its 8:3 file name, in order to exclude any spaces from the path, which cause scripting problems.

Eclipse Setup Procedure for Windows

As of Eclipse uses the PATH environment variable to search the JVM to run. In Windows the path to the default installation of JAVA executable contains a space, which causes problems in resolving Maven dependencies referring ${java.home} in Eclipse environment. Therefore it is needed to set the path to JAVA using the 8:3 file names:

  • Edit eclipse.ini file in the Eclipe’s root directory:
  • Add before the -vmargs line the contents:

where the path is an example of the 8:3 reference to the javaw.exe of of the JVM to use.

Maven Setup Procedure for Windows

  • Install Maven in a directory
  • Set the environment variable:
M2_HOME = <Maven installation directory in **8:3 name format**>
  • Include in the environment PATH:
  • Edit the %M2_HOME%\bin\mvn.cmd file (Windows) after @setlocal insert the lines:
if "%DEBUG_PORT%" == "" set DEBUG_PORT=8000
set MAVEN_DEBUG_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=%DEBUG_SUSPEND%,address=%DEBUG_PORT%
  • Edit the %MAVEN_HOME%\config\settings.xml file and add a common active settings profile for any installation-wide sproperties, where are replaced with actual values:

        <name>Repository of any public/external maven plugins/tools.</name>

           Any external components of modelant.
           It is isolated to allow analysis of vulnerabilities, licenses, etc. imposed through dependencies


NOTE: The components (transitive dependencies) of the modelant, that are used in runtime, are collected in the public-components repository, separated from the components of Maven (any other tools) used in compile time. This allows analyzing them as the whole repository contents for vulberabilities and security risks. Nexus provides such analysis.

Compile and Deploy Skipping tests


  • The test of the API package are specifications of the API and black-box tests of any implementation (IMPL) behind the API.
  • While compiling the API tests, there is no implementation yet, so these tests fail.
  • Maven complains when test-scoped dependencies establish cyclic graph.
  • The failed API tests block publishing the API, which fails the compilation of the IMPL module.
  • Moving the API tests into the IMPL module degrades them to control of a single implementation.


  • Extracted is a separate test module to be processed last.
  • All integration/API tests are moved there, while keeping the unit tests in the modules.
  • The test module does not contain actual implementation (only tests).

Thus, run as separate commands:

  • In the components projects:
mvn clean deploy
  • In the integration test project:
mvn test
  • Or just in the common root project:
mvn install

Install, Skip Tests

As of Skipping Tests:

  • Skip running the tests, but compile them:
mvn install -DskipTests
  • Skip even compiling the tests:
mvn install -Dmaven.test.skip=true

Debug a Test

The default in Modelant project is Maven to run the tests in a dedicated JVM. The control on the debug port and suspend of that JVM is done through the POM properties:

DEBUG_PORT (default: 7000)
DEBUG_SUSPEND (default: n)


mvn test -DDEBUG_SUSPEND=y

Debug a Maven Plugin

Maven runs the plugins in the same JVM that runs Maven. According to the setup procedure, the control of the Maven JVM is done through the OS environment variables:

DEBUG_PORT (default: 8000)
DEBUG_SUSPEND (default: n)


mvn test

Analyze the Maven phase-to-plugin & goal bindings

mvn fr.jcgay.maven.plugins:buildplan-maven-plugin:list-phase

Build the modelant site

Use the “sites” generated for the modelant’s modules and combine them in a single site by calling the site plugin:

mvn site:site

The site is produced in the modelant’s taget/staged-site directory.

Deploy it to the hosting site with:

mvn site:deploy

Or just call the site-deploy phase of the site lifecycle:

mvn site-deploy

Publish in Maven Central

In order to publish the modelant components in Maven Central (through OSSHR) activate the production profile:

  • In root pom.xml change the modelant version to a release version - remove the -SNAPSHOT suffix
  • Run
mvn clean deploy -P production
  • Log in OSSRH/Sonatype staging repository
  • In Build Promotion \ Staging Repositories menu find the net.mdatools repository
  • Close the repository
  • In the Activity tab review the status of the components if they pass the quality gates.
  • If the artifacts did not pass the quality gates:
    • drop the repository
    • fix the problems locally
    • repeat the procedure
  • In case the of passed quality gates, the components will be uploaded to Maven Central
