7.4. Configuring Maven to Use Online Repositories

The online repositories required for Red Hat JBoss BPM Suite applications are located at https://maven.repository.redhat.com/ga/.

It is possible to configure Maven to use online repositories using the project’s POM file, but this is not recommended.

Procedure: Configuring Maven to Use 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>https://maven.repository.redhat.com/ga/</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>jboss-ga-plugin-repository</id>
          <url>https://maven.repository.redhat.com/ga/</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>

  <servers>
    <!-- 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>
    -->
  </servers>

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

</settings>

  2. If you modified the settings.xml file while Red Hat 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 Red Hat 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 — and run mvn clean install -U. This will force Maven to download correct versions of required artifacts when performing the next build.
