Talend Job JAR Files Location

Wawee — Sat, 16 Nov 2024 00:12:51 GMT

Talend Cloud Real-Time Big Data Platform V7.3.1

Questions:

1) How to identify the directory/location of the JAR files that the Talend job is looking into?

2) How to edit or force Talend job to point to the JAR file location without using tLibraryLoad component?

Note: Frequent issue of Java error, NoClassDefFoundError, even though the JAR files/modules have already been installed and/or added to the routine library of the code and the Talend job has been setup with the routine dependency. Needed JAR files are also existing in the following directory:

<InstalledTalendDirectory>\configuration\.m2\repository

Example:

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

JAR file exist in

<InstalledTalendDirectory>\configuration\.m2\repository\org\apache\logging\log4j\log4j-api\2.12.1\log4j-api-2.12.1.jar

Same JAR file added in the routine library of the code.

HI, go to window --> show view -->Java --> Package Explorer:

then go to (your_Project_name) go to Maven Dependencies : you will see the path of all the jar.

Thanks for your reply; but there is no Maven Dependencies under the Project name like in the following:

Yes; I found the Maven Dependencies there. Thanks; I'll check it.

Talend can't still locate the classpath in the jar file even after explicitly specifying the jar file location.

Have you try to restart Talend?

Yes. I have restarted Talend and also tried the following:

Re-ordered build path to move Maven Dependencies at the top.
Re-extracted/Re-installed Talend.
