Package the application

Type the following command


E:/Test/TestApplication/> spring jar TestApplication.jar *.groovy

Now you can see two new files created in TestApplication folder.

TestApplication.jar − An executable jar file.

TestApplication.jar.original − Original jar file.

*.jar files

E:/Test/TestApplication/> java -jar TestApplication.jar

You can see the following output on console.
