How to retain edited .java file of a Talend job?

Wawee — Sat, 16 Nov 2024 00:12:10 GMT

Talend Cloud Real-Time Big Data Platform version 7.3.1

Tried editing the Talend job's java code in the following location:

<TalendInstallationDirectory>\workspace\<ProjectName>\poms\jobs\process\<JobName>\src\main\java\<project_name>\<jobname>\<jobname>.java

The purpose is to try to resolve the following Java error during Talend job execution:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/logging/log4j/LogManager

The following line of code was added:

import org.apache.logging.log4j.LogManager;

After re-executing the Talend job, the added line of code is automatically being deleted. How do I enforce Talend application to retain the modified code in <jobname>.java file?

Note: I have already tried the following.

Added tLibraryLoad component; but this is not the recommended solution since exporting and importing the Talend job to others' similar Talend setup does not have any issue on the NoClassDefFoundError
Explicitly added/installed the module/Jar file in the routine code's library.
Explicitly added the Jar file in the Package Explorer of the project's Maven Dependencies
Re-ordered build path to move Maven Dependencies on top.
Lastly, even re-extrated/re-installed a new & fresh Talend application; but still encountering the same Java error that Talend cannot locate the class path in the specified jar file.
Modified the project's java code but it is automatically being removed; so posted this topic for question.

Hi maybe you could use :

File --> project Settings --> Maven

and you will see a window where you can force the synchronization of the poms.

and in filter : label=your job name

Send me Love and Kudos
