Steps:-

Download this commons-net.jar file
Extract the zip file
Copy the Jar file
Place the file in lib folder of your project.
Right click on the project
On left side of list, click on "Java Build Path"
Click on Libraries tab and Click on "Add Jar"
Browse the Commons-net.jar file and click on insert

Solution 2

Here's the official Apache download site for Commons Net.

Once you've picked and extracted the appropriate version, set a dependency in your Eclipse project:

Right-click the project and choose "Properties"
Choose "Java Build Path" from the resulting popup
Set up the dependency in the "Libraries" tab.

The dependency does not need to be local to your project, but may be.

If you'd like a project-relative library, drop the jar into an appropriate project-relative location. For project libraries, choose "Add Jars" in the "Libraries" tab; for external libraries, choose "Add External Jars".

Solution 3

If you're working in a Maven project, you will need to add commons-net as a dependency

     <dependency>
            <groupId>commons-net</groupId>
            <artifactId>commons-net</artifactId>
            <version>3.6</version>
    </dependency>

In Eclipse, the following import...
```
import org.apache.commons.net.ftp.FTPClient;
```
...produces the following error message...
```
The import org.apache cannot be resolved
```
I do not know how to import, nor where to download the import (if necessary). I might need a click-by-click set of Eclipse directions to resolve this.

Alternative for steps 5-8: rightclick JAR file in project, Build Path > Add to Build Path.

Thanks. When you say 'Place the file in lib...', In eclipse, I assume the 'lib' folder you wrote is the 'JRE System Library' folder(?). Assuming that is correct, if I right click on 'JRE System Library', there are many options. I will guess* it is one of the 'General' options(?). Under 'General',I will guess* the correct option is 'File System'(?).

Here lib folder is the project related folder. So it requires all others steps 5-8

Thanks again. For future reference, the folder referred to as 'lib' is a top-level 'blue folder' in Eclipse. Please correct me if I am wrong. Also, what is the Google or location strategy for finding a particular jar file?

The /lib folder is just a folder which you create yourself (rightclick project, New > Folder). You can of course also put the JAR straight in project root structure. The /lib folder is not mandatory, but just a common practice to collect all dependency JARs in one place. Do for sure not put it in "JRE System Library" or something.
