Procedure
-
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.
-
In the tree view of the dialog box, click the Log4j node to open the Log4j view.
-
Select the Activate log4j in
components check box to activate the Log4j feature.
By default, the Log4j feature is activated and Log4j 2 is enabled when a project is created.
When a project is imported from Talend 7.2 or an earlier version, which only supports Log4j 1, the deprecated Log4j 1 is selected from the Log4j version drop-down list by default. All POM files for the project will be synchronized when you change the Log4j version.
Note: If you need to deploy your Jobs to Talend Cloud, the use of Log4j 2 requires Talend Remote Engine 2.8.1 or higher. -
If needed, change the global Log4j configuration by modifying
the XML instructions in the Log4j
template area.
For example, to configure the root logger for Log4j 2 to output all debug or higher messages, go to the Loggers section and set the value of the level attribute of the root node to debug.
For more information about Log4j 2 configuration, see http://logging.apache.org/log4j/2.x/manual/configuration.html#XML.
