  4. Click Install to install all plugins at once without restarting the Jenkins server.

Configuring paths to Git and Maven tools

Store the environment variables and paths to the third-party tools needed to run your Jenkins pipeline (Git, Maven).
  1. Navigate to Manage Jenkins > Tools.
  2. In the Git installations area, add the Git executable. Either enter the path to your Git executable file, or select the Install automatically check box if you want to install a new one automatically.
  3. In the Maven installations area, add the M3 Maven tool. Either Enter the path to your Maven installation directory in the MAVEN_HOME field, or select the Install automatically check box if you want to install a new one automatically.
  4. Click Save to take the changes into account.

Storing your login credentials in Jenkins

Store the login credentials of your source control management tool and deployment containers (Docker, Amazon AWS, Azure, etc.) in Jenkins.
  1. Navigate to Manage Jenkins > Credentials.
  2. Click System > Global credentials > Add Credentials and add the Git credentials to access the repository where your project items (Jobs, Routes, Tests, etc.) are stored.

    If you are using Git personal access tokens, select Username with password. If you are using SSH, select SSH username with private key in the list.

  3. Name its ID git_talend, this identifier will be used in the Jenkins pipeline.
  4. Click Create to take the changes into account.

Storing your configuration files in Jenkins

  1. Download and extract these files:
  2. In Jenkins, navigate to Manage Jenkins > Managed files.
  3. Click Add a new Config and select Maven settings to add the Maven configuration file.
  4. Give it a name and an ID, maven_settings. This identifier will later be used in the Jenkins pipeline.
  5. In the Content editor, paste the content of the maven_settings.xml file you have previously downloaded.
    • The default Nexus artifactory URL defined in the file (line 40) is localhost:8080. Update the value according to your environment.

    • For Big Data users with dynamic distributions only: add the following server and repository to the configuration file in order to define the Nexus local repository as proxy, ensuring faster .jar file downloading:

      <server>
    <id>dynamic-distrib</id>
    <username>admin</username>
    <password>Talend123</password>
</server>
      <repository>
    <id>dynamic-distrib</id>
    <name>dynamic-distrib</name>
    <url>http://localhost:8081/repository/dynamic-distrib/</url>
    <layout>default</layout>
 </repository>

      For this configuration to be complete, you need to have previously added the Talend proxy in the Talend Studio Project settings > General > Dynamic Distribution Settings menu.

  6. Click Submit.
  7. Click Add a new config and select Groovy file to add the Jenkins helper configuration file.
