If you need to add a new configuration action, click and from the list that opens, select the desired option. return String.valueOf(fizzBuzz); In our tutorial we use the open JDK 14 version. The result of the test will be displayed in the Run tool window. It might be helpful, when the classpath entries have changed. } } When the code is compiled and ready, you can package your application in a Java archive (JAR) to share it with other developers. } The project used in this tutorial can be found on GitHub. From the main menu, select File | Project Structure Ctrl+Alt+Shift+S and click Artifacts. You can change the selected JDK, IntelliJ IDEA will download the appropriate Gradle version. The results of the background compilation are dislplayed in the Problems tool window. If you select the Build, no error check option, IntelliJ IDEA will run the application even if there are errors in the compilation results. In this case, the dependencies that for some reason were not included in the build with the Build action, will be accounted for. In this case, the build delegation to Gradle or Maven can help you build your project correctly. } Assert.assertEquals("Fizz", fb.convert(3)); To the right of the Main Class field, click and select the main class in the dialog that opens (for example, HelloWorld (com.example.helloworld)). If any two JAR files contain classes with the same name, the IntelliJ IDEA compiler will use the classes from the first JAR file it locates in the classpath. } In the Gradle tool window, click on the toobar. Open the main class FizzBuzzProcessor in the editor. } option selected in the System settings dialog. On the toolbar, select the created configuration and click to the right of the run configuration selector. Assert.assertEquals("2", fb.convert(2)); As you can see, the Run tool window displays information obout the failed test including the specific line of the code where the error occurred. It builds and runs succesfully, and after building jar with the gradle panel on the right in intellij, I try to run it with. group 'org.example' If you do so (say, specify some instead of /out) but don't redefine the paths at the module level, the compilation results will go to /production/ and /test/. IntelliJ IDEA creates the build directory that contains our JAR file. If the dependent module has its own module dependencies, then IntelliJ IDEA compiles all of them recursively starting with the least dependent module. testCompile group: 'junit', name: 'junit', version: '4.12' You can configure IntelliJ IDEA to build your project automatically, every time you make changes to it. When you compile your source code, IntelliJ IDEA automatically creates an output directory that contains compiled .class files. Assert.assertEquals("1", fb.convert(1)); FizzBuzzProcessor fb = new FizzBuzzProcessor(); IntelliJ IDEA creates the artifact configuration and shows its settings in the right-hand part of the Project Structure dialog. return "FizzBuzz"; In the Additional Libraries and Frameworks area IntelliJ IDEA selects the default option Java which is what we need for our project. If you have a Gradle project, use Gradle to create and run the JAR file. Alternatively, you can execute the run task under the application node. attributes "Main-Class": "com.gradle.tutorial.FizzBuzzProcessor" }, jar { mavenCentral() if (fizzBuzz % 15 == 0) { if (fizzBuzz % 5 == 0) { return "Buzz"; /out/production/. In the Path to JAR field, click and specify the path to the JAR file on your computer. IntelliJ IDEA also creates the src folder with main and test subdirectories in the Project tool window. Doing this means that the JAR is built automatically every time you execute the run configuration. Note that the build task includes the test task that Gradle executes. }, Publish a Java library to a Maven repository. Open the needed file in the editor and from the main menu, select, Select a module or a project you want to compile and from the main menu, select. FizzBuzzProcessor fb = new FizzBuzzProcessor(); from { In the New Java Class dialog specify a name of your Java class and click OK. As before, the Run tool window opens and shows you the application output. If you have a Spring Boot Maven project, refer to the Spring section. Open the Project Structure dialog (File | Project Structure Ctrl+Alt+Shift+S). We add the name FizzBuzzTest and leave the rest of the default options as is and click OK. Now open the created test class and add the following code: Let's quickly run the application to see if it works. In the Project tool window open the src folder. If you need, you can execute the clean command before the rebuild using the Execute Before Rebuild option in the Gradle or Maven tool window. After we've created our project and it finished indexing, let's see what is inside: As you can see, IntelliJ IDEA conviniently adds a test dependency. If you have a pure Java or a Kotlin project we recommend that you use IntelliJ IDEA to build your project since IntelliJ IDEA supports the incremental build which significantly speeds up the building process. In the Run/Debug Configurations dialog, click and select JAR Application. If you configured an auto-build, then IntelliJ IDEA uses the Problems tool widow for messages. version '1.0-SNAPSHOT' Assert.assertEquals("Buzz", fb.convert(5)); @Test Let's add id 'application' to the plugins section and the following code: If we check the build directory now, we'll see that IntelliJ IDEA created additional directories. For Maven projects, you can use IntelliJ IDEA to run the JAR file. In the dialog that opens, create a new or open an existing run configuration. }, package com.gradle.tutorial; Point to the created .jar (HelloWorld:jar) and select Build. You can run the created JAR file in the command line with java -jar command. From the project type pane on the left, choose Gradle. }, application { import org.junit.Test; When you change any class inside the build target and then execute the build action, IntelliJ IDEA performs the incremental build that compiles only the changed classes. The way the module dependencies are ordered may be very important for the compilation to succeed. } When you execute a rebuild command, IntelliJ IDEA cleans out the entire output directory, deletes the build caches and builds a project, or a module from scratch. In our case it is FizzBuzzProcessor. In the Project tool window, double click the build.gradle file to open it in the editor. In the left gutter, click and select Run 'FizzBuzzProcessor.main()'. In this tutorial, we will show you how to use Gradle build tool to create a single Jar file with dependencies.. Tools used : Gradle 2.0; JDK 1.7; Logback 1.1.2; 1. When the Rebuild Project action is delegated to Gradle or Maven, IntelliJ IDEA doesn't include the clean task/goal when rebuilding a project. If you want to change that behavior, you can do so in the Run/Debug Configurations dialog. When you execute a rebuild command, IntelliJ IDEA cleans out the entire output directory, … On the welcome screen, click New Project. The IntelliJ IDEA compilation and building process compiles source files and brings together external libraries, properties files, and configurations to produce a living application. So, if we make a mistake in one of our tests, the test task will fail and the build task will fail as well. So, if we decide to add more dependencies, IntelliJ IDEA will quickly locate their names and versions. public void FizzBuzzNormalNumbers() { The default paths for subdirectories are as follows: Sources: /out/production/, Tests: /out/test/. At the project level, you can change the /out part of the output path. Now let's create a Java application that outputs the first 100 FizzBuzz numbers. public static String convert(int fizzBuzz) { At the module level, you can specify any desirable compilation output location for the module sources and tests individually. If you add a module dependency to your primary module and build the module, IntelliJ IDEA builds the dependent module as well and displays it in the output directory alongside the primary one. To the options on the right, IntelliJ IDEA automatically adds a project SDK (JDK). repositories { Add the following code to the main FizzBuzzProcessor class: Our application is ready. We can run our test from the editor or from the Gradle tool window using the test task. @Test Create executable jar file intellij idea. } } In … For example, SDKs or libraries that the project uses are added, removed or altered. }, package com.gradle.tutorial; However, IntelliJ IDEA native builder might not correctly build the Gradle or Maven project if its build script file uses custom plugins or tasks. Creating a Gradle-Based IntelliJ Platform Plugin with New Project Wizard New Project Configuration Screen. Now right-click the package and select New | Java Class. Press Ctrl+Shift+A, find and run the Edit Configurations action. Specify the Project SDK based... Project Naming/Artifact Coordinates Screen.

When you have the Power Save Mode option (File | Power Save Mode) enabled in your project, the auto-build action is disabled, and you need to manually run the build (Ctrl+F9). manifest { Change the location of the output folder under the Compiler output section. We will use this window to run our tasks. If we change the default number in one of the tests, it will fail. A built Java archive is called an artifact. On the next page of the wizard let's specify our project's name (FizzBuzz) and the location. Run configurations allow you to define how you want to run your application, with which arguments and options. public void FizzBuzzThreeNumbers() { By default, when you run an application, IntelliJ IDEA compiles the module where the classes you are trying to run are located. Create following project folder structure : @Test public class FizzBuzzProcessor { The only thing you need to have is the internet connection. Inside the output directory, IntelliJ IDEA also creates subdirectories for each of your modules. public class FizzBuzzTest { dependencies { Click in the editor to load the changes to your project. The project structure (Ctrl+Alt+Shift+S) contains information about the project's JDK and a language level used in the project. In the dialog that opens, let's make sure that our testing library is JUnit4 and the destination package is com.gradle.tutorial. mainClassName = 'com.gradle.tutorial.FizzBuzzProcessor' You can have multiple run configurations for the same application, each with its own settings. } Double-click a message to jump to the problem in the source code. [Gradle] build, jar 배포, IntelliJ 설정 ... jar 배포 및 실행. IntelliJ IDEA enables the dedicated Gradle tool window with a liked project and its default tasks. Open the main class FizzBuzzProcessor in the editor, place the caret at the class name and press Ctrl+Shift+T. From the main menu, select Build | Build Artifacts. Rebuild. To run a Java application packaged in a JAR, IntelliJ IDEA allows you to create a dedicated run configuration. The automatic build also gets triggered when you save the file (Ctrl+S) or when you have the Save files automatically if application is idle for N sec. In this tutorial, we'll create a Gradle project, will run and test it, and run the executable JAR file using Gradle. for (int i = 1; i <= 100; i++) { Java project with Gradle and building jar file in Intellij IDEA - how to? IntelliJ IDEA also recursively builds the classes' dependecies. If the process has exited successfully, then the application is packaged correctly. public void FizzBuzzFiveNumbers() { New to Gradle, and trying to make a executable jar so I can run my project on a raspberry PI.
