Installing components using a CAR file

Components built using Talend Component Kit can be shared as component archives (.car). These CAR files are executable files allowing to easily deploy the components it contains to any compatible version of Talend Studio.

Component developers can generate .car files from their projects to share their components and make them available for other users, as detailed in this document.

This document assumes that you have a component archive (.car) file and need to deploy it to Talend Studio.

Deploying from the CAR file to Talend Studio

The component archive (.car) is executable and exposes the studio-deploy command which takes a Talend Studio home path as parameter. When executed, it installs the dependencies into the Studio and registers the component in your instance. For example:

# for a studio
java -jar studio-deploy /path/to/my/studio
java -jar studio-deploy --location /path/to/my/studio

# for a m2 provisioning
java -jar maven-deploy /path/to/.m2/repository
java -jar maven-deploy --location /path/to/.m2/repository

You can also upload the dependencies to your Nexus server using the following command:

java -jar deploy-to-nexus --url <nexus url> --repo <repository name> --user <username> --pass <password> --threads <parallel threads number> --dir <temp directory>

In this command, Nexus URL and repository name are mandatory arguments. All other arguments are optional. If arguments contain spaces or special symbols, you need to quote the whole value of the argument. For example:

--pass "Y0u will \ not G4iess i' ^"

Deploying a component archive to a remote project from Talend Studio

Talend Studio allows you to share components you have created using Talend Component Kit to other users working on the same remote project.

Remote projects are available with Enterprise versions of Talend Studio only.

Make sure you are connected to a remote project and the artifact repository for component sharing has been properly configured.

  1. On the toolbar of the Studio main window, click or click File > Edit Project Properties from the menu bar to open the Project Settings dialog box.

  2. In the tree view of the dialog box, select Repository Share to open the corresponding view.

  3. Select the Propagate components update to Artifact Repository check box.

  4. In the Repository ID field, specify the artifact repository configured for component sharing, and then click Check connection to verify the connectivity.

  5. Click Apply and Close to validate the settings and close the dialog box.

  6. Create a folder named patches at the root of your Talend Studio installation directory, then copy the .car files of the components you want share to this folder.

  7. Restart your Talend Studio and connect to the remote project.

The components are deployed automatically to the repository and available in the Palette for other users when connected to a remote project with the same sharing repository configuration.
