You can edit the library of any of the user routines by importing external .jar files for the selected routine. These external library files will be listed, like modules, in the Modules view in your current Studio. For more information on the Modules view, see the Talend Installation Guide.
The .jar file of the imported library will be also listed in the library file of your current Studio.
To edit a user routine library, complete the following:
In the Repository tree view, expand Code > Routines.
Right-click the user routine you want to edit its library and then select Edit Routine Library.
The [Import External Library] dialog box displays.
Click New to open a new dialog box where you can import the external library.
You can delete any of the already imported routine files if you select the file in the Library File list and click the Remove button.
Enter the name of the library file in the Input a library's name field followed by the file format (.jar), or
Select the Browse a library file option and click browse to set the file path in the corresponding field.
If required, enter a description in the Description field and then click OK to confirm your changes.
The imported library file is listed in the Library File list in the [Import External Library] dialog box.
Click Finish to close the dialog box.
The library file is imported into the library folder of your current Studio and also listed in the Module view of the same Studio.
