Use IntelliJ IDEA to create an EXECUTABLE JAR With Dependencies Using Maven

Video Description

In this video, we will use IntelliJ IDEA to create an executable jar file using Maven. Keep watching until the end of the video to see a second way to create an executable jar that will take up less space in your deployments, so you can optimize your images. We're using IntelliJ IDEA Community Edition, which is free. Using IntelliJ is a great way to make programming more productive and enjoyable. ▬▬▬▬▬▬ T I M E S T A M P S ⏰ ▬▬▬▬▬▬ 00:00 *Create the project* 02:30 *Review Maven setup* 03:10 *Add first dependency* 03:40 *Security Alert* 05:45 *Add second dependency* 07:41 *Execute the jar file* 09:19 *Modify the code to include the dependency* 11:15 *Package the dependency* 12:19 *Build the artifact* 14:02 *Add Maven plugin to project* 15:10 *Build the code with the new plugin* When IntelliJ is working, I have sped up the boring parts, so we can focus on what's interesting IntelliJ creates our project and provides us with a very basic pom.xml. We see the group and artifact id we provided earlier in our pom file, along with the default version of the 1.0 snapshot. Any recent version of java will be fine, we’ll be using version 11. In the project tool window, we’ll right click on source, main, java and select new java class We’ll supply the name of the package and the class file name at one time Let’s call it com dot beginsecure dot app and press return Intellij creates our class Lets use the live template psvm to generate our main method And we’ll use the live template sout to generate our printline statement In our message, let’s put in the string hello world because of course And let’s run that code just to show that everything is working correctly We see the code runs, prints our message and exits with a return code of 0 Great, everything is working as expected, Let’s take a moment and look at the maven tool window On top we see a list of the lifecycle phases, clean, validate, compile and so forth. A phase is a step in the build lifecycle which is an ordered sequence of steps When a phase, like package, is specified, every phase in the sequence up to and including the one specified is run Below is a list of the plugins that are available to use by default from IntelliJ IDEA When we invoke plugins, we specify a goal to perform. For example, the plugin we might invoke is compiler and the goal is compile Back in the Project tool window, we see the external libraries this project is dependent on For now, JDK 11 is the only thing necessary to build this project Let’s change that and explore how we can add a dependency to our project You can find the code here: https://github.com/BeginSecure/IntelliJExecutableJar.git
