我可以使用Java Scripting API将kotlin作为脚本运行

Question

我想用Java脚本运行kotlin代码作为脚本,Java脚本API类似于javascript:

import javax.script.*;
public class EvalScript {
    public static void main(String[] args) throws Exception {
        // create a script engine manager
        ScriptEngineManager factory = new ScriptEngineManager();
        // create a JavaScript engine
        ScriptEngine engine = factory.getEngineByName("JavaScript");
        // evaluate JavaScript code from String
        engine.eval("print('Hello, World')");
    }
}

或者像这样的类似API.

是的,可以从Kotlin 1.1开始:http://kotlinlang.org/docs/reference/whatsnew11.html#javaxscript-support

此配置将Kotlin脚本引擎添加到我的Kotlin 1.2项目中:

• META-INF/services/javax.script.ScriptEngineFactory包含https://github.com/JetBrains/kotlin/blob/master/libraries/examples/kotlin-jsr223-local-example/src/main/resources/META-INF/services/javax.script内容的文件. ScriptEngineFactory所

• 2个图书馆: <dependency> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-script-runtime</artifactId> <version>${kotlin.version}</version> </dependency> <dependency> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-script-util</artifactId> <version>${kotlin.version}</version> </dependency>

更新: 从Kotlin 1.2.20开始kotlin-script-util并不kotlin-compiler明确依赖(参见https://youtrack.jetbrains.com/issue/KT-17561).因此应该提供另外一个模块(从示例项目中的构建文件开始): <dependency> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-compiler-embeddable</artifactId> <version>${kotlin.version}</version> </dependency>
