![]() Now, we can debug the class by clicking on the debug icon from the Run/Debug configuration. IntelliJ has great support for debugging many languages. Let's debug our String Reversal utility as an example.Īs with most IDEs, we can add a breakpoint on any line of our class from the editor by clicking on the side panel: We'll also pass a String – “ baeldung“ , in this case – as a Program Argument to our application.Īnd, while we won't demo this here, we can also configure JVM options and environment variables, too, for our application.Ĭontrary to temporary run configurations, IntelliJ saves this configuration and allows us to execute it any time with a click of a button. ![]() It needs to have a main method for this to work. Here, we specify the name of our class to run in Main Class. We'll do that using the “ Edit Configurations” window from the Run Navigation bar ( Run->Edit Configurations): So, we can create a permanent Run/Debug Configuration. However, since we have to pass a String to our StringReversal application as a program argument (the args part), a temporary run configuration won't work. IntelliJ will then create a temporary Run configuration. Firstly, we can simply run Ctrl + Shift +F10 or Control + Shift + R/D from the main class. Now, there are 2 approaches for running this main method in IntelliJ. In the next section, we'll use this library and execute a simple Java program. Find file intellij portable#Of course, remember that adding a library this way is IntelliJ-specific and not as portable as more robust options. It's convenient, though, for simple projects. Along with that, it also adds it to the project classpath. Find file intellij download#IntelliJ will now download the commons-lang3.jar into a specified folder. And of course, if no repository is configured, it will search the Maven Central. Normally, the common source for any external library is the Maven Repository. Hence, IntelliJ allows us to download it directly from any pre-configured Maven repository. In order to add the library, we must download it first. Both global and project specific libraries can be added by accessing the Project Structure dialog ( File->Project Structure). Like the JDK settings, we can also configure libraries at global and project level. Global libraries are shared by all projects. Let's say we want to use the StringUtils API from the commons-lang3 library. Find file intellij how to#And while Maven and Gradle are the typical go-tos for managing this, let's take a look at how to do this natively in IntelliJ. In the Environment variables section as seen below, copy and paste the following, replacing the values with your own.A Java project usually depends on a lot of external or third-party libraries. in the dropdown as seen below:Īnother window displaying the "Run/Debug Configurations" will pop up with the details regarding the project.Ĭreate an Application named "SMSApp". Locate the Run tab at the top of the IntelliJ IDEA console and select Edit Configurations. Give your project a name such as "sms_variables" and click the Finish button.Īfter the project setup is complete and the build has succeeded, your project directory structure should look like the following image:Īdd environment variables to an application Open IntelliJ IDEA and click on Create New Project.Ĭhoose Gradle on the left hand side, check Java in the box on the right hand side, and click Next.
