DO NOT WORRY, the Cloudsim simulation toolkit setup or you can say the installation of cloudsim is very easy. This Cloudsim tutorial is going to take you through the steps by step journey.

Now before you start to setup CloudSim, the following resources must be Installed/downloaded on the local system

Cloudsim simulation toolkit setup is easy. Before you start to set up CloudSim, the following resources must be Installed/downloaded on the local system

Note: Installation steps are almost similar for Windows as well as Linux computer system. 

Let’s Get Started to answer the “How to install Cloudsim?”

First of all, navigate to the folder where you have unzipped the Eclipse folder and open Eclipse.exe

Now within Eclipse window navigate the menu: File -> New -> Project, to open the new project wizard

A ‘New Project‘ wizard should open. There are a number of options displayed and you have to find & select the ‘Java Project‘ option, once done Click ‘Next

Now a detailed new project window will open, here you will provide the project name and the path of the CloudSim project source code, which will be done as follows:

Make sure you navigate the path till you can see the bin, docs, examples, etc folder in the navigation plane.

Once done finally, click ‘Next’ to go to the next step i.e. setting up of project settings

Now open the ‘Libraries’ tab and if you do not find commons-math3-3.x.jar (here ‘x’ means the minor version release of the library which could be 2 or greater) in the list then simply click on Add External Jar’ (commons-math3-3.x.jar will be included in the project from this step)

Once you have clicked on ‘Add External JAR’s‘ Open the path where you have unzipped the commons-math binaries and select ‘Commons-math3-3.x.jar’ and click on Open.

Ensure the external jar that you opened in the previous step is displayed in the list and then click on ‘Finish’ (your system may take 2-3 minutes to configure the project)

Once the project is configured you can open ‘Project Explorer’ and start exploring the Cloudsim project. Also for the first time eclipse automatically start building the workspace for the newly configured Cloudsim project, which may take some time depending on the configuration of the computer system.

Following is the final screen which you will see after Cloudsim is configured.

Now just to check you within the ‘Project Explorer‘, you should navigate to the ‘examples‘ folder, then expand the package ‘org.cloudbus.cloudsim.examples‘ and double click to open the ‘‘.

Now navigate to the Eclipse menu ‘Run -> Run‘ or directly use a keyboard shortcut ‘Ctrl + F11’ to execute the ‘‘.

if it is successfully executed it should be displaying the following type to output in the console window of the Eclipse IDE.

If Yes then Congratulations!! Now you have successfully set up/Installed the CloudSim Simulation Toolkit on your computer machine and you are ready to start with the experimentation for your further research work.

Did you encounter an error during the setup of cloudsim?

If you have encountered some error then the eclipse may look like this:

Most of the time, the type of error that you may encounter during setting up of the cloudsim in Eclipse should be stating either:
“Syntax error, parameterized types are only available if source level is 1.5 or greater.”


“Syntax error ‘for each’ statements are only available if source level is 1.5 or greater.”

These errors occur due to two reasons:
Case 1: The version of Java installed on your computer system is older than 1.5
Case 2: Your default Java environment for the Eclipse project is not set to the latest Java version which is available on your computer system.

For Case 1, you have to download and install the latest Java version from Oracle/Java website.

For Case 2, you have to do some modifications to the eclipse project, and for this, you should follow these steps:

  1. In the Eclipse IDE menu, click on ‘Project’ and from the dropped menu list click on ‘Properties’ to open a project properties window.
  2. On the project properties window, from the list available on the left select ‘Java Compiler’, this will display the compiler options.
  3. Now, click on the ‘Enable Project Specific Settings’ checkbox, which further enables the options provided just below the checkbox.
  4. Now, under the JDK compliance heading change the ‘Compiler Compliance Level’ to the highest number available on the list.
  5. Also, make sure “Use default compliance settings” should be in the checked state.
  6. Now, click on the “Apply and Close” button. Now a popup alert will be displayed asking for confirmation to apply the settings. Click ‘Yes’.

Now you will notice that the rebuild process for the project will get started and confirm the error is resolved or not. You may check the error log window or run any example class available in org.cloudbus.cloudsim.examples namespace.
