You can edit the library of a user routine by importing external libraries (usually .jar files) for it.
If you have installed the R2021-03 Studio monthly update or a later one provided by Talend, you can import external libraries for an inner routine by editing the library of the custom routine jar in which the inner routine is bundled.
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 Installing external modules to Talend Studio.
The imported library will be also listed in the library file of your Studio.
About this task
To edit the library for a user routine or a custom routine jar, complete the following:
Procedure
-
If the library to be imported is not
available on your machine, either download and install it using the Modules view or download and store it in a local
directory.
-
In the Repository tree view, right-click the user routine or the custom routine jar and then select Edit Routine Libraries or Edit Routine Jar libraries.
The Import External Library dialog box displays.
The Maven Uri column is available only if you have installed the R2020-11 Studio monthly update or a later one provided by Talend.
-
Click New... to open the Module dialog box where you can import the external library.
-
If you have
installed the library using the Modules view, select the Platform option and then select the library from
the list, or
-
If you have stored
the library file in a local directory, select the Install a new module option, and click the [...] button to browse to the library file.
If the MVN
URI of the library exists in the file <TalendStudio>\configuration\MavenUriIndex.xml, it is
automatically filled in the Default MVN URI field.
- If you have not installed the R2020-10 Studio monthly
update or a later one provided by Talend, and if you need to customize the Maven URI of
the library, select the Custom MVN URI check box, specify the
new URI, and then click the Detect the module install status button
to validate its installation status.
- If you have installed the R2020-10 Studio monthly
update or a later one provided by Talend, and if the MVN URI of the library is within the
jar file, it is automatically detected and filled in the Custom MVN URI field if it is different
from the default MVN URI. Select the Custom MVN URI check box if you want to
change the custom Maven URI or use the custom Maven URI to install the
library. If neither the default MVN URI nor the custom MVN URI exists,
the Default MVN URI field is filled with
mvn:org.talend.libraries/<jarname>/6.0.0-SNAPSHOT/jar.
-
Click OK to confirm your changes.
The imported library file is listed in the Library File list in the Import External Library dialog box.
Note: You can delete any of the already imported routine files if you select the file in the Library File list and click Remove.
-
To include the external libraries when building your Job as a standalone Job to be
executed out of Talend Studio,
select the corresponding Required check box. Otherwise, you
will get the "class not found" error when the Job is executed.
By default, the Required check box is selected for each
imported library.
If you have imported Camel or CXF libraries and you need to build your Job as an
OSGI bundle to be deployed on Talend Runtime, it
is recommended that you clear the Required check box to avoid
issues caused by duplicate class paths, as those libraries are already provided with
Talend Runtime
bundles.

Click Finish to close the dialog box.
