7.4. Configuring Maven to Use the Online Repositories

The online repositories required for Red Hat JBoss BPM Suite applications are located at http://maven.repository.redhat.com/techpreview/all/.
If you did not configure the Maven repository during installation, you can configure it using the following procedure. (It is also possible to do this using the project's POM file, but this is not recommended.)

Procedure 7.2. Configuring Maven to Use the Online Repositories

  1. Add entries for the online repositories and configuration of authentication for accessing them to Maven's settings.xml file as in the code sample below: 
    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <profiles>
    <!-- Profile with online repositories required by BRMS/BPMS -->
    <profile>
      <id>brms-bpms-online-profile</id>
      <repositories>
        <repository>
          <id>jboss-ga-repository</id>
          <url>http://maven.repository.redhat.com/techpreview/all</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>jboss-ga-plugin-repository</id>
          <url>http://maven.repository.redhat.com/techpreview/all</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>

  <!-- Configuring pre-emptive authentication for the repository server -->
  <server>
    <id>brms-bpms-m2-repo</id>
    <username>admin</username>
    <password>admin</password>
    <configuration>
      <wagonProvider>httpclient</wagonProvider>
      <httpConfiguration>
        <all>
          <usePreemptive>true</usePreemptive>
        </all>
      </httpConfiguration>
    </configuration>
  </server>

  <!-- Alternative to enabling pre-emptive authentication - configuring
       the Authorization HTTP header with Base64-encoded credentials
  <server>
    <id>brms-bpms-m2-repo</id>
    <configuration>
      <httpHeaders>
        <property>
          <name>Authorization</name>
          <value>Basic YWRtaW46YWRtaW4=</value>
        </property>
      </httpHeaders>
    </configuration>
  </server>
  -->

  <activeProfiles>
    <!-- Activation of the BRMS/BPMS profile -->
    <activeProfile>brms-bpms-online-profile</activeProfile>
  </activeProfiles>

</settings>
  2. If you modified the settings.xml file while JBoss Developer Studio was running, you must refresh Maven settings in the IDE. From the menu, choose Window → Preferences. In the Preferences Window, expand Maven and choose User Settings. Click the Update Settings button to refresh the Maven user settings in JBoss Developer Studio.

Result

Maven has been configured to use the online repositories provided for your Red Hat JBoss product.

Important

If your cached local Maven repository contains outdated artifacts, you may encounter one of the following Maven errors when you build or deploy your project:
  • Missing artifact ARTIFACT_NAME
  • [ERROR] Failed to execute goal on project PROJECT_NAME; Could not resolve dependencies for PROJECT_NAME
To resolve the issue, delete the cached local repository – the ~/.m2/repository/ directory on Linux or the %SystemDrive%\Users\USERNAME\.m2\repository\ directory on Windows. This will force Maven to download correct versions of required artifacts during the next build.
