第一步：打开idea

第二步：添加依赖

<repositories><repository><id>mavenCentral</id><url>https://repo1.maven.org/maven2/</url></repository></repositories><build><sourceDirectory>src/main/kotlin</sourceDirectory><testSourceDirectory>src/test/kotlin</testSourceDirectory><plugins><plugin><groupId>org.jetbrains.kotlin</groupId><artifactId>kotlin-maven-plugin</artifactId><version>1.9.21</version><executions><execution><id>compile</id><phase>compile</phase><goals><goal>compile</goal></goals></execution><execution><id>test-compile</id><phase>test-compile</phase><goals><goal>test-compile</goal></goals></execution></executions></plugin><plugin><artifactId>maven-surefire-plugin</artifactId><version>2.22.2</version></plugin><plugin><artifactId>maven-failsafe-plugin</artifactId><version>2.22.2</version></plugin><plugin><groupId>org.codehaus.mojo</groupId><artifactId>exec-maven-plugin</artifactId><version>1.6.0</version><configuration><mainClass>MainKt</mainClass></configuration></plugin></plugins></build><dependencies><dependency><groupId>org.jetbrains.kotlin</groupId><artifactId>kotlin-test-junit5</artifactId><version>1.9.21</version><scope>test</scope></dependency><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-engine</artifactId><version>5.10.0</version><scope>test</scope></dependency><dependency><groupId>org.jetbrains.kotlin</groupId><artifactId>kotlin-stdlib</artifactId><version>1.9.21</version></dependency></dependencies>

它自己会下载所需依赖，依赖位置：C:\Users\Administrator\.m2\repository\org\jetbrains

下载速度会很慢，咱们要不换个镜像或者挂t都行

第三步：运行示例代码
