Fat Jar Eclipse Plug-In Tutorial


Step 1: Create a new Java Project "demolib"

Create a new Java Project named "demolib".
Add the Class "demolib.DemoLib.java" containing the following code:

package demolib;

public class DemoLib {
public static void sayHello() {
System.out.println("Hello");
}
}

The Project should look something like this:


Step 2: Create a jar file using Fat Jar Plug-In

In the "Package-Explorer" (not the "Resource-View") right click on the project "demolib".
Select "+ Build Fat Jar".

A Configuration Dialog appears. Just press "Finish".

The File "demolib_fat.jar" has been created in the project root directory.


Step 3: Create a new Java-Project "demorun"

Create a new Java Project named "demorun".
In the project properties add the Library "demolib/demolib_fat.jar" to the Java Build Path":


Step 4: Create Main Class

Add the Class "demorun.DemoRunMain.java" containing the following code:

package demorun;

import demolib.DemoLib;

public class DemoRunMain {
public static void main(String[] args) {
DemoLib.sayHello();
}
}

The Project should look something like this:


Step 5: Start the Build Fat Jar Dialog

Start the Export Wizard from the File-Menu ("File" -> "Export").
Select "+ Fat Jar Exporter" and click "next >".

Select the project "demorun" and click "next >".

Step 6: Select the Main Class

The Main Class - the one containing the static methode main - must be defined in the jar.
Click on the "Browse..." Button on the right side behind the Main-Class Edit field.

Select "DemoRunMain" and click the "OK" Button.
The FullyQualifiedName "demorun.DemoRunMain" is now set for "Main-Class".


Step7: Finish

Save the current Settings by clicking on the "Finish" Button.

The File "demorun_fat.jar" has been created in the project root directory.
In addition the file ".fatjar" storing the
