All tasks should be done only with raw JDK tools:

• javac
• jar
• etc

1. Create Client interface JAR

Create new project and declare new interface named Client, that will have following contract:

public interface Client{
    void setName(String name);
    void sayHello();
}

Create custom manifest file and fill following properties with your information:

• Specification-Title - The value is a string that defines the title of the extension specification
• Specification-Vendor - The value is a string that defines the organization that maintains the extension specification
• Build-Date - The value is a string that defines the date on which JAR file was build in following format: YYYY-MM-DD

Be sure to have appropriate package structure.

Prepare .bat/.sh script that should perform following:

• compile Client interface
• create .jar file with compiled class and custom MANIFEST.MF

2. Create Client implementation executable JAR

Create new project and declare new implementation of Client interface named ConsoleClient.

This implementation should work with user input and system error output.

Create Main class, that creates new Client instantiated with ConsoleClient instance and:

• ask for user name
• greet user

Create custom manifest file and fill following properties with your information:

• Main-Class - The value is a string that denotes entry point of application
• Specification-Title - The value is a string that defines the title of the extension specification
• Specification-Vendor - The value is a string that defines the organization that maintains the extension specification
• Build-Date - The value is a string that defines the date on which JAR file was build in following format: YYYY-MM-DD

Prepare .bat/.sh script that should perform following:

• compile ConsoleClient and Main classes
• create executable .jar file

Prepare .bat/.sh script that should perform following:

• run executable .jar file with needed dependencies
