If you need to install user-defined components (that you developed locally or downloaded from Talend Exchange for example), then you need to notify the CommandLine with the user component folder.
To configure the path to these components, simply use the following command:
setUserComponentPath -up <UserComponentPath>
To clear this path, type in the command:
setUserComponentPath -c
Note
You can also configure the user component path directly from the Configuration page of Talend Administration Center. For more information, see the Talend Administration Center User Guide.
