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.
Install Java JDK
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.
Set the JAVA_HOME environment variable on a Windows machine
Step 1: Open the System Control panel. Then select the Advanced tab.
Above: View of the Advanced tab within System Properties.
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.
