Step 1: Verify Java Installation in Your Machine
First of all, open the console and execute a java command based on the operating system you are working on.
| OS | Task | Command |
|---|---|---|
| Windows | Open Command Console | c:> java -version |
| Linux | Open Command Terminal | $ java -version |
| Mac | Open Terminal | machine:< joseph$ java -version |
Let”s verify the output for all the operating systems −
| OS | Output |
|---|---|
| Windows |
Java 11.0.11 2021-04-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.11+9-LTS-194)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.11+9-LTS-194, mixed mode)
|
| Linux |

If you do not have Java installed on your system, then download the Java Software Development Kit (SDK) from the following link www.oracle.com/technetwork/java/javase/downloads/index.html. We are assuming Java 11.0.11 as the installed version for this tutorial.
Step 2: Set JAVA Environment
Set the JAVA_HOME environment variable to point to the base directory location where Java is installed on your machine. For example.
| OS | Output |
|---|---|
| Windows | Set the environment variable JAVA_HOME to C:Program FilesJavajdk11.0.11 |
| Linux | export JAVA_HOME = /usr/local/java-current |
| Mac | export JAVA_HOME = /Library/Java/Home |
Append Java compiler location to the System Path.
| OS | Output |
|---|---|
| Windows | Append the string C:Program FilesJavajdk11.0.11bin at the end of the system variable, Path. |
| Linux | export PATH = $PATH:$JAVA_HOME/bin/ |
| Mac | not required |
Verify Java installation using the command java -version as explained above.
Step 3: Download jsoup Archive
Download the latest version of jsoup jar file from Maven Repository. At the time of writing this tutorial, we have downloaded jsoup-1.14.3.jar and copied it into C:>jsoup folder.
| OS | Archive name |
|---|---|
| Windows | jsoup-1.14.3.jar |
| Linux | jsoup-1.14.3.jar |
| Mac | jsoup-1.14.3.jar |
Step 4: Set jsoup Environment
Set the JSOUP_HOME environment variable to point to the base directory location where jsoup jar is stored on your machine. Let”s assuming we”ve stored jsoup-1.14.3.jar in the JSOUP folder.
| Sr.No | OS & Description |
|---|---|
| 1 |
Windows
Set the environment variable JSOUP_HOME to C:JSOUP |
| 2 |
Linux
export JSOUP_HOME = /usr/local/JSOUP |
| 3 |
Mac
export JSOUP_HOME = /Library/JSOUP |
Step 5: Set CLASSPATH Variable
Set the CLASSPATH environment variable to point to the JSOUP jar location.
| Sr.No | OS & Description |
|---|---|
| 1 |
Windows
Set the environment variable CLASSPATH to %CLASSPATH%;%JSOUP_HOME%jsoup-1.14.3.jar;.; |
| 2 |
Linux
export CLASSPATH = $CLASSPATH:$JSOUP_HOME/jsoup-1.14.3.jar:. |
| 3 |
Mac
export CLASSPATH = $CLASSPATH:$JSOUP_HOME/jsoup-1.14.3.jar:. |
