Refresh the Maven project in the Maven Projects tool window (Reimport All Maven Projects), if it doesn't help, refer to this answer for diagnostics.

The issue is that your source roots were not configured correctly from the Maven model for some reason and the .java file appears in a plain directory instead of the Source root.

You can tell that by the color of the folders and by the icon of the file.

There are multiple ways by which we can run our Java application. The commonly used ones are either from the command line or from the IDE itself.

From command line

1. java -jar command.

   Example: java -jar jar-name.jar

2. java -cp command.

   Example: java -cp jar-name.jar com.package.ClassName

where com.package.ClassName is the class that contains the main method to run the program. cp in the above command stands for the classpath.

From IDE

Simply do the right-click in the class and you will be able to find the option to run your code. Just click on that option. Check this image for detail.

Please follow the following steps:

1. Set the maven goal by clicking the "+" in IntelliJ (circled area)

2. Write mvn install.

3. Set the VM Options as: -Dspring.profiles.active=development

After that it should just run fine just by clicking the green play button.

There are 2 things you can do:

You can right-click your project root in the "Maven Projects" view and select the "Create XXX [install]..." option (where XXX is your project/module name. Then, in the subsequent dialog, specify clean install -U as the command line option. This will create a run configuration that invokes maven (you can name it "update" if you want). While it won't show up in the Maven view, it will be accessible from the normal run/debug configuration.

Alternatively, you can define a new profile in your pom that rebinds "install" to "clean install -U". You won't be able to rename it to "update" in the intelliJ ui, but you can at least ensure that both clean and install are run whenever someone runs the install goal.

If You have created maven profiles in your pom.xml, you should be able to see the profiles in right side of Intellij Idea

If there will be multiple profile you can activate one by default

           <activation>
                <activeByDefault>true</activeByDefault>
            </activation>

Or for running specific profile we can select mvn install -Pbuild-profile

IDEA manages Maven profiles via the Maven Tool Window (View -> Tool Windows -> Maven). So in order to apply a Maven Profile to your Project you would have to do the following:

1. Activate the desired Profile via the Tool Window. (see IDEA Documentation)
2. Click "Reload All Maven Projects" button in the Tool Window so it applies the changes.
3. Run your Spring Boot Configuration as normal and it should pick up Maven Profile you've selected.

Let me know if it works for you!

Welcome Manan! You should be able to create a target for the jar application in IntelliJ by following these steps.

EDIT: Upon initially reading your question I didn't see you already had the steps for creating a new jar configuration, but I'll leave the images here for future readers.

First, open your run/debug configurations in the top right:

Then create a new configuration with the plus:

Enter the appropriate information for the jar. I've edited and shown what you should use. (Comments aren't valid and for demonstration)

You can run or debug the configuration by selecting from the dropdown and selecting the required button. ctrl-d debugs and ctrl-r runs by default.

To expand upon what you should enter for the fields (see the image above for your exact configuration):

• Path to jar: This is the file path of your jar. Notice how you can use the dots on the right to locate it easily.
• VM options: These are the options for controlling the JVM. For example, the -Xmx1200m sets the maximum RAM of the JVM. I tested what I showed for your configuration. You can separate them with spaces as you would on the command-line.
• Program arguments: These are the arguments you would feed to your program if you invoked it via the command-line as java programName arguments.
• Environment variables can be set with name and value via the three dots on the right and then the plus in the bottom left. For you these would include key=jsse.enableSNIExtension and value=false. I'm pretty confident about removing the D, but may be wrong there. Let me know via your testing if it's wrong.
• JRE: Leave to default unless desired otherwise.
• Search sources using module's classpath: If your module is configured correctly you can leave this to Default.
• Before launch: Activate tool window: You can add other tasks to create cool chains of tasks.

Note you can directly run your Maven project without creating a jar first, just in case that's what you're doing. Also, the -XX:MaxPermSize=256M appears to be deprecated and using address 30306 caused an error when I tested, but an arbitrary 5005 did work.
