Setting Java Development Kit (JDK) Environment Variables
In Provar, Apache ANT can be used to run a Provar test suite via the command line or you can use a Continuous Integration (CI) server such as Jenkins. Before a build file can be generated, first install Java Development Kit (JDK) and configure the environment variables. You can follow the steps below to complete these actions.
How To Install Java Development Kit
Step 1: Download the compatible version of Java JDK. Visit the Oracle website and download a compatible version of Java JDK.
Compatible versions include:
- 1.8.0.162, 1.8.0.172, 1.8.0.201, 1.8.0.211, 1.8.0.221
Note: You can reference the Java version mismatch error support article to learn how to resolve related error messages.
Step 2: Complete the installation by following the prompts. Be sure to take note of the installation directory information, e.g C:\Program Files\Java\jdk1.8.0_221. You will need to add this information as part of the environment variable settings later in this process.

Step 2: Click the Environment Variables button. The following dialog box will appear.
Above: View of the Environment Variables dialog box.
Step 3: Click the New button below System variables.
Step 4: Within the Variable name field, enter JAVA_HOME. Within the Variable value field, enter the directory where Java JDK was extracted previously, e.g. C:\Program Files\Java\jdk1.8.0_221.
Step 5: Then click the OK button.
Above: View of New System Variable dialog box.
Step 6: Go to the Path variable within the System variables section and click on the Edit button.
Step 7: Click the New button and type %JAVA_HOME%\bin in the row at the bottom of the list.
Step 8: Click OK and restart your system.
Step 9: To verify that you have installed the correct Java version, open the command prompt and type the following command:
Java -version
Set the JAVA_HOME Environment Variable on a Mac
Step 1: Navigate to your user home directory. The fastest way to do this is using Shift + Command + H or you can open Finder, select Go in the menubar and then click Home.
Step 2: Find the .bash_profile. The .bash_profile may be hidden. If so, use command+shift+period to make hidden files visible.
Note: The command above does include a period/dot after the second plus sign.
Step 3: If you still do not see the .bash_profile, use the following command within the terminal to display the file:
touch .bash_profile.
Step 4: Right-click on the .bash_profile file and select Open With > TextEdit.
Step 5: Add the following command:
export JAVA_HOME=$(/usr/libexec/java_home)
Step 6: Export JAVA_HOME to PATH with the following command:
export PATH=$PATH::$JAVA_HOME/bin
Step 7: Now restart your machine or use the following command:
source ~/.bash_profile
Step 8: Type the following command:
java -version.
Note: It should now display the JDK version information. The subversion may be different from the screenshot below.
