Java 9のJShellにgsonライブラリをインポートするにはどうすればよいですか？

jshell> import com.google.gson.*

jshell> /import
| import java.io.*
| import java.math.*
| import java.net.*
| import java.nio.file.*
| import java.util.*
| import java.util.concurrent.*
| import java.util.function.*
| import java.util.prefs.*
| import java.util.regex.*
| import java.util.stream.*
| import com.google.gson.*

jshell> Gson g = new GsonBuilder().setPrettyPrinting().create()
g ==> {serializeNulls:false,factories:[Factory[typeHier ... 78b9],instanceCreators:{}}

以下のコードスニペットでは、従業員を作成しました クラス。

jshell> class Employee {
...>       private String firstName;
...>       private String lastName;
...>       private String designation;
...>       private String location;
...>       public Employee(String firstName, String lastName, String desigation, String location) {
...>          this.firstName = firstName;
...>          this.lastName = lastName;
...>          this.designation = designation;
...>          this.location = location;
...>       }
...>       public String getFirstName() {
...>          return firstName;
...>       }
...>       public String getLastName() {
...>          return lastName;
...>       }
...>       public String getJobDesignation() {
...>          return designation;
...>       }
...>       public String getLocation() {
...>          return location;
...>       }
...>       public String toString() {
...>          return "Name = " + firstName + ", " + lastName + " | " +
...>                 "Job designation = " + designation + " | " +
...>                 "location = " + location + ".";
...>       }
...>    }
| created class Employee

jshell> Employee e = new Employee("Jai", "Adithya", "Content Developer", "Hyderabad");
e ==> Name = Jai, Adithya | Job designation = Content D ... er | location = Hyderabad.

jshell> String empSerialized = g.toJson(e)
empSerialized ==> "{\n \"firstName\": \"Jai\",\n \"lastName\": \" ... ation\": \"Hyderabad\"\n}"

以下のコードスニペットでは、従業員のインスタンスを作成できます オブジェクトを作成して結果を表示します。

jshell> System.out.println(empSerialized)
{
   "firstName": "Jai",
   "lastName": "Adithya",
   "designation": "Content Developer",
   "location": "Hyderabad"
}
jshell> Employee e1 = g.fromJson(empSerialized, Employee.class)
e1 ==> Name = Jai, Adithya | Job designation = Content D ... er | location = Hyderabad.
