VMware vSphere Automation SDK for Java

Table of Contents


This document describes the vSphere Automation Java SDK samples that use the vSphere Automation java client library. Additionally, some of the samples demonstrate the combined use of the vSphere Automation and vSphere Web Service APIs. The samples have been developed to work with JDK 1.8.

Supported OnPrem vCenter Releases:

vCenter 6.0, 6.5, 6.7, 6.7U1, 6.7U2, 6.7U3, 7.0, 7.0U1, 7.0U2

Please refer to the notes in each sample for detailed compatibility information.

VMware Cloud on AWS Support:

The VMware Cloud on AWS API and samples are currently available as a preview and are subject to change in the future.

Quick Start Guide

This document will walk you through getting up and running with the Java SDK Samples. Prior to running the samples you will need to setup a vCenter test environment and install maven, the following steps will take you through this process. Before you can run the SDK samples we'll need to walk you through the following steps:

  1. Setting up maven
  2. Setting up a vSphere test environment

Setting up maven

The SDK requires maven to build the samples.

  1. Download the latest maven from and extract it to your machine.
  2. Install JDK8 and set JAVA_HOME to the directory where JDK is installed.
    export JAVA_HOME=<jdk-install-dir>
  3. Update PATH environment variable to include the maven and jdk "bin" directories.
    export PATH=<maven-bin-dir>:$JAVA_HOME/bin:$PATH

Setting up a vSphere Test Environment

NOTE: The samples are intended to be run against a freshly installed non-Production vSphere setup as the scripts may make changes to the test environment and in some cases can destroy items when needed.

To run the samples a vSphere test environment is required with the following minimum configuration

  • 1 vCenter Server
  • 2 ESX hosts
  • 1 NFS Datastore with at least 3GB of free capacity

Apart from the above, each individual sample may require additional setup. Please refer to the sample parameters for more information on that.

Building the Samples

In the root directory of your folder after cloning the repository, run the below maven commands -

mvn initialize

mvn clean install

Running the Samples

When running the samples, parameters can be provided either on the command line, in a configuration file (using the --config-file parameter), or a combination of both. The parameter values specified on the command line will override those specified in the configuration file. When using a configuration file, each required parameter for the sample must be specified either in the configuration file or as a command line parameter. Each parameter specified in the configuration file should be in the "key=value" format. For example:



Note: Please specify the fully qualified “hostname” of the server for running the samples to avoid hostname verification errors.

Use a command like the following to display usage information for a particular sample.

$java -ea -cp target/vsphere-samples- vmware.samples.vcenter.vm.list.ListVMs

java -cp target/vsphere-samples- vmware.samples.vcenter.vm.list.ListVMs [--config-file <CONFIGURATION FILE>]
       --server <SERVER> --username <USERNAME> --password <PASSWORD> --cluster <CLUSTER> [--truststorepath <ABSOLUTE PATH OF JAVA TRUSTSTORE FILE>]
       [--truststorepassword <JAVA TRUSTSTORE PASSWORD>] [--cleardata] [--skip-server-verification]

Sample Options:
    --config-file <CONFIGURATION FILE>                         OPTIONAL: Absolute path to  the configuration file containing the sample options.
                                                               NOTE: Parameters can be specified either in the configuration file or on the command
                                                               line. Command line parameters will override values specified in the configuration file.
    --server <SERVER>                                          hostname of vCenter Server
    --username <USERNAME>                                      username to login to the vCenter Server
    --password <PASSWORD>                                      password to login to the vCenter Server
    --truststorepath <ABSOLUTE PATH OF JAVA TRUSTSTORE FILE>   Specify the absolute path to the file containing the trusted server certificates. This
                                                               option can be skipped if the parameter skip-server-verification is specified.
    --truststorepassword <JAVA TRUSTSTORE PASSWORD>            Specify the password for the java truststore. This option can be skipped if the
                                                               parameter skip-server-verification is specified.
    --cleardata                                                OPTIONAL: Specify this option to undo all persistent results of running the sample.
    --skip-server-verification                                 OPTIONAL: Specify this option if you do not want to perform SSL certificate
                                                               NOTE: Circumventing SSL trust in this manner is unsafe and should not be used with
                                                               production code. This is ONLY FOR THE PURPOSE OF DEVELOPMENT ENVIRONMENT.

Use a command like the following to run a sample using only command line parameters:

$java -ea -cp target/vsphere-samples- vmware.samples.vcenter.vm.list.ListVMs --server servername --username administrator@vsphere.local --password password --skip-server-verification

Use a command like the following to run a sample using only a configuration file:

$java -ea -cp target/vsphere-samples- vmware.samples.vcenter.vm.list.ListVMs --config-file

Use the following command to run the sample using a combination of configuration file and command line parameters:

$java -ea -cp target/vsphere-samples- vmware.samples.vcenter.vm.list.ListVMs --config-file --server servername

Importing the samples to eclipse

To generate the eclipse project files for the samples run the below command

mvn eclipse:clean eclipse:eclipse

Once generated, follow below steps to import the project to eclipse:

  1. Go to File -> Import.
  2. Select Existing Projects into Workspace.
  3. Select the root directory as the directory where the samples are located.
  4. Click Finish

Adding a new sample

Once the eclipse project is imported, follow below steps to add a new sample using the sample template:

  1. Right click on the project and select New -> Package. Specify a package name in the wizard and click Finish.
  2. Right click on the newly created package and click Import -> General -> File System. In the dialog box, click "Browse" and select the "sample-template" folder in the root directory.
  3. Select the "SampleClass" in the dialog box and click finish.

This will import a basic sample class to your package, which you can then customize according to your needs.
