Spring Maven LogFactory NoClassDefFoundError Logging Project

I have a Maven project that uses Spring to run the json web service. The project works great in NetBeans. It compiles to a jar file, and the jar file works fine in the Ubuntu VM. However, when I try to run the jar file on Windows, I get the following error.

java -jar myjar.jar --server.port = 8000

I spent the whole day trying to figure it out, but to no avail.

Can anyone shed some light?

This is my pom.xml below.

The Spring Framework uses the Apache Commons logging API for logging. In the Spring parent POM, there is an explicit Commons registration library exception for loading.

 <exclusion> <artifactId>commons-logging</artifactId> <groupId>commons-logging</groupId> </exclusion>

This means that you have to provide the selected implementation of Commons Logging for Spring classes at run time.

You can add a public entry to your POM, the latest version is 1.2, released in July 2014.

 <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency>

Or you can connect the Apache Commons registration API to the SLF4J Api (see http://www.slf4j.org/legacy.html ) using jcl-over-slf4j.jar, and then add the SLF4L implementation of your choice. For instance:

 <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-simple</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> </dependency>

You have included the following in your commons-logging dependency:

 <scope>provided</scope>

This is an instruction to prevent commons-logging from being included in your bank. Consequently, he is not on his way to classes.
