In the Path to JAR field, click and specify the path to the JAR file on your computer. We can run our test from the editor or from the Gradle tool window using the test task. For more information, see Module dependencies. IntelliJ IDEA also creates the src folder with main and test subdirectories in the Project tool window. IntelliJ IDEA creates the artifact configuration and shows its settings in the right-hand part of the Project Structure dialog. mavenCentral() Assert.assertEquals("Fizz", fb.convert(3)); Doing this means that the JAR is built automatically every time you execute the run configuration. public void FizzBuzzNormalNumbers() { From the main menu, select Build | Build Artifacts. @Test When you execute the Build command, IntelliJ IDEA compiles all the classes inside your build target and places them inside the output directory. Add the following code to the main FizzBuzzProcessor class: Our application is ready. FizzBuzzProcessor fb = new FizzBuzzProcessor(); If you configured an auto-build, then IntelliJ IDEA uses the Problems tool widow for messages. You can change the selected JDK, IntelliJ IDEA will download the appropriate Gradle version. Create following project folder structure : 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. 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). public class FizzBuzzTest { Assert.assertEquals("2", fb.convert(2)); Click in the editor to load the changes to your project. We will use this window to run our tasks. When the Rebuild Project action is delegated to Gradle or Maven, IntelliJ IDEA doesn't include the clean task/goal when rebuilding a project. } } To run a Java application packaged in a JAR, IntelliJ IDEA allows you to create a dedicated run configuration. Create executable jar file intellij idea. Assert.assertEquals("Buzz", fb.convert(5)); }, package com.gradle.tutorial; Click in the left gutter of the editor. In the Run/Debug Configurations dialog, click and select JAR Application. 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. IntelliJ IDEA displays the build results in the Review compilation and build output. In the Project tool window open the src folder. You can have multiple run configurations for the same application, each with its own settings. The project used in this tutorial can be found on GitHub. Click , point to JAR, and select From modules with dependencies. In this case, the dependencies that for some reason were not included in the build with the Build action, will be accounted for. dependencies { In the Settings/Preferences dialog Ctrl+Alt+S , go to Build, Execution, Deployment | Compiler. } Open the Project Structure dialog (File | Project Structure Ctrl+Alt+Shift+S). public void FizzBuzzThreeAndFiveNumbers() { if (fizzBuzz % 15 == 0) { Java project with Gradle and building jar file in Intellij IDEA - how to? However, IntelliJ IDEA native builder might not correctly build the Gradle or Maven project if its build script file uses custom plugins or tasks. At the project level, you can change the /out part of the output path. 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. You can configure IntelliJ IDEA to build your project automatically, every time you make changes to it. manifest { Now let's create a Java application that outputs the first 100 FizzBuzz numbers. Alternatively, press Shift+F10 if you prefer shortcuts. Now right-click the package and select New | Java Class. When you compile your source code, IntelliJ IDEA automatically creates an output directory that contains compiled .class files. } We will use the editor. If you select the Build, no error check option, IntelliJ IDEA will run the application even if there are errors in the compilation results. As you can see, the build and test actions are delegated to Gradle. For example, SDKs or libraries that the project uses are added, removed or altered. FizzBuzzProcessor fb = new FizzBuzzProcessor(); To the options on the right, IntelliJ IDEA automatically adds a project SDK (JDK). public static String convert(int fizzBuzz) { On the toolbar, select the created configuration and click to the right of the run configuration selector. IntelliJ IDEA uses a compiler that works according to the Java specification. From the main menu, select File | Project Structure Ctrl+Alt+Shift+S and click Artifacts. IntelliJ IDEA creates the build directory that contains our JAR file. [Gradle] build, jar 배포, IntelliJ 설정 ... jar 배포 및 실행. Note that the build task includes the test task that Gradle executes. } The IntelliJ IDEA compilation and building process compiles source files and brings together external libraries, properties files, and configurations to produce a living application. You can compile a single file, use the incremental build for a module or a project, and rebuild a project from scratch. As before, the Run tool window opens and shows you the application output. On the welcome screen, click New Project. Open the main class FizzBuzzProcessor in the editor. The way the module dependencies are ordered may be very important for the compilation to succeed. IntelliJ IDEA supports code completion inside the build.gradle file. @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. If we change the default number in one of the tests, it will fail. In this case, the build delegation to Gradle or Maven can help you build your project correctly. }, Publish a Java library to a Maven repository. Double-click a message to jump to the problem in the source code. If you have a Gradle project, use Gradle to create and run the JAR file. Assert.assertEquals("Buzz", fb.convert(5)); If errors occure during the compilation process, IntelliJ IDEA will display them in the Review compilation and build output along with warning messages. } public void FizzBuzzThreeNumbers() { } /out/production/. public void FizzBuzzFiveNumbers() { mainClassName = 'com.gradle.tutorial.FizzBuzzProcessor' If the process has exited successfully, then the application is packaged correctly. FizzBuzzProcessor fb = new FizzBuzzProcessor(); 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. Open the main class FizzBuzzProcessor in the editor, place the caret at the class name and press Ctrl+Shift+T. } return String.valueOf(fizzBuzz); For Maven projects, you can use IntelliJ IDEA to run the JAR file. }, application { How to build jars from IntelliJ properly?,from Add drop down menu. The default paths for subdirectories are as follows: Sources: /out/production/, Tests: /out/test/. In this tutorial, we'll create a Gradle project, will run and test it, and run the executable JAR file using Gradle. 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. Under Before launch, click , select Build Artifacts in the dialog that opens. } Assert.assertEquals("1", fb.convert(1)); Project Directory. Press Ctrl+Shift+A, find and run the Edit Configurations action. } 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. option selected in the System settings dialog. The project structure (Ctrl+Alt+Shift+S) contains information about the project's JDK and a language level used in the project. On the next page of the wizard let's specify our project's name (FizzBuzz) and the location. Running `` gradle build`` from terminal, switching to /build/libs and then running `` java -jar artifactname`` works just fine. On the page that opens, from the options on the left select Gradle. import org.junit.Assert; From the project type pane on the left, choose Gradle. Run configurations allow you to define how you want to run your application, with which arguments and options. In the New Java Class dialog specify a name of your Java class and click OK. On the page that opens, from the options on the left select Gradle. For example, if you select Build Project then IntelliJ IDEA will build the whole project before the run. Click Finish. } Now let's build our application to create an executable 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. In the Project tool window, double click the build.gradle file to open it in the editor. If you need to add a new configuration action, click and from the list that opens, select the desired option. If you want to change that behavior, you can do so in the Run/Debug Configurations dialog. In our case it is FizzBuzzProcessor. Change the location of the output folder under the Compiler output section. In … FizzBuzzProcessor fb = new FizzBuzzProcessor(); So, if we decide to add more dependencies, IntelliJ IDEA will quickly locate their names and versions. In the left gutter, click and select Run 'FizzBuzzProcessor.main()'. From the main menu, select Run | Edit Configurations. Click the main directory then right-click the java subdirectory and from the list select New | Package. For modules, select Modules, the module you need and the Paths tab. 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. Select "From modules with dependencies" How to create a .jar using IntelliJ IDEA 14.1.5: File > Save All. public static void main(String[] args) { Specify the Project SDK based... Project Naming/Artifact Coordinates Screen. The window is availble even if the build was executed successfully. The result of the test will be displayed in the Run tool window. A built Java archive is called an artifact. You can run the created JAR file in the command line with java -jar command. Also, the Gradle wrapper was used to determine Gradle for our project. We should have the same result as when we ran the application in the IntelliJ IDEA editor. Now, let's create the necessary tests for it. java -jar .\build\libs\ It then gets an error: Error: Could not find or load main class org.openjfx.MainApp version '1.0-SNAPSHOT' In our tutorial we use the open JDK 14 version.

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. 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. Alternatively, you can execute the run task under the application node. By default, when you run an application, IntelliJ IDEA compiles the module where the classes you are trying to run are located. In the dialog that opens, create a new or open an existing run configuration. return "Fizz"; In the Gradle tool window, click on the toobar. } for (int i = 1; i <= 100; i++) { IntelliJ IDEA also recursively builds the classes' dependecies. Inside the output directory, IntelliJ IDEA also creates subdirectories for each of your modules. 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. The only thing you need to have is the internet connection. @Test Save files automatically if application is idle for N sec. attributes "Main-Class": "com.gradle.tutorial.FizzBuzzProcessor" }, package com.gradle.tutorial; We can use the default information for ArtifactId which basically is the name of our project and leave the default information in the version and GroupId fields. System.out.println(convert(i)); Create a new Gradle Project with IntelliJ IDEA On the welcome screen, click New Project. 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/. } At the module level, you can specify any desirable compilation output location for the module sources and tests individually. IntelliJ IDEA reports compilation and building results in the Build tool window, which displays messages about errors and warnings as well as successful steps of compilation. If you now look at the out/artifacts folder, you'll find your .jar file there. if (fizzBuzz % 3 == 0) { plugins { repositories { In the dialog that opens, let's make sure that our testing library is JUnit4 and the destination package is com.gradle.tutorial. If for some reason you closed this window, you can always access it from the main menu by selecting View | Tool Windows | Gradle. testCompile group: 'junit', name: 'junit', version: '4.12' it : zipTree(it) } from { }, jar { return "FizzBuzz";
