Answer 1

Add this to your pom file:

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

It works for me after adding this jar file

You can download it from here .

Include jarernate jar files (especially necessary jars) in the lib folder

I had a similar problem: in my project, the solution was to add the following org.apache.commons banks:

Common Log-1.2 Common-dbcp2-2.1.1 Common-pool2-2.4.2

For me, the problem is resolved after loading and adding jar "commons-logging-1.2.jar"
