The type org.apache.commons.logging.Log cannot be resolved. It is indirectly ref

This error message usually occurs when there is a problem with the classpath or dependencies.

First, make sure that you have added the required dependencies to your project's classpath. In this case, it seems that you are missing the Apache Commons Logging library.

You can download the latest version of the commons-logging library from the Apache Commons website and add it to your project's classpath.

If you are using a build tool like Maven or Gradle, you can add the dependency to your project's pom.xml or build.gradle file respectively.

For example, to add the commons-logging dependency in a Maven project, you can add the following code to your pom.xml file:

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

Once you have added the dependency, rebuild your project and try running it again. The error message should disappear.
