I'm using Eclipse and Maven on this project. I need to keep the log4j.properties file available for change after the code is packaged into a JAR file therefore I can't put that file in src/main/resources as mentioned in this post.

I found this post saying that I could add arguments to my Java call but I really wanted to do that by configuration (if possible, of course).

This reply to the first mentioned post was the closest solution I could find. It shows how to make properties files exported along with the JAR package file.

However I can't make it work when I put the properties file in a folder called CONF. Anyone can tell what I'm doing wrong? Check below my project structure and a portion of my pom.xml.

Project Structure .

Problem solved. Some lines were missing on my POM file, directly in the project tree.

<properties>
    <log4j.configuration>conf/log4j.properties</log4j.configuration>
</properties>

In my case the settings with the ./conf did not work with log4j , but after I changed to ./conf/ it was OK.
