如何在IntelliJ中通过Gradle标准方式运行Java项目？

Hey there! Let's walk through your questions with practical, standard practices for Gradle and IntelliJ:

1. Are there other standard ways to run the project? #

Absolutely! Here are some common approaches besides right-clicking the main class:

• IntelliJ Run Configurations: You can create a dedicated run configuration (via Run > Edit Configurations) for your main class. This lets you set VM options, program arguments, environment variables, and reuse the configuration easily across sessions.
• Gradle Tool Window: Open the Gradle tool window (usually pinned to the right side of IntelliJ), navigate to your module's Tasks > application folder, and double-click the relevant run task to launch the project.
• Command Line: You can run the project directly from your terminal using Gradle commands (we’ll cover the specific task next).

2. Which Gradle task should I execute to run the project? #

If you’re using the standard Java plugin (applied by default for Gradle Java projects in IntelliJ), the built-in task to run your application is run.

To execute it:

• On macOS/Linux: Run ./gradlew run in your project root directory
• On Windows: Run gradlew.bat run in your project root directory

If Gradle doesn’t automatically detect your main class (unlikely in your single-class setup), you can explicitly define it in your build script:
For Groovy DSL (build.gradle):

plugins {
    id 'application'
}

mainClassName = 'your.package.name.YourMainClass'

For Kotlin DSL (build.gradle.kts):

plugins {
    application
}

application {
    mainClass.set("your.package.name.YourMainClass")
}

3. Does everyone only run the project by right-clicking the main() method? #

Nope! Right-clicking the main method is super convenient for daily development, quick testing, and debugging—it’s what most developers reach for when iterating on code locally.

But in other scenarios, people use different methods:

• Team Collaboration & CI/CD: When running the project in shared environments or automated pipelines, everyone relies on the standard Gradle run task via command line. This ensures consistency, as it avoids IDE-specific configurations that might not translate across machines.
• Complex Setups: If your project requires specific VM arguments, environment variables, or depends on other modules being built first, using a dedicated run configuration or Gradle task is more reliable.
• Automation: Scripts or build pipelines will always use Gradle tasks instead of IDE interactions, since they need to run without a graphical interface.

So while the right-click method is common for local development, it’s far from the only way—Gradle tasks are essential for standardized, automated runs.
