无法使用公地EXEC运行命令行中使用Java时触发摇篮测试

Question

它是如此的有线，我不能跑“NPM -v”当我在的IntelliJ

public class Main { 
    public static void main(String[] args) throws IOException, InterruptedException { 
     DefaultExecutor executor = new DefaultExecutor(); 
     executor.execute(CommandLine.parse("npm -v")); 
    } 
} 

public class MainTest { 
    @Test 
    public void name() throws Exception { 
     Main.main(new String[]{}); 
    } 
} 

运行测试用例的摇篮插件一切工作正常，当我：用罐子
1.启动应用
2.使用的IntelliJ触发测试用例（右键点击并运行“MainTest”）
3.运行gradle clean check

但是当我运行使用摇篮插件测试，永远变得不安。

输出是

:compileJava 
:processResources NO-SOURCE 
:classes 
:compileTestJava UP-TO-DATE 
:processTestResources NO-SOURCE 
:testClasses UP-TO-DATE 
:test

让我知道如果你需要多少信息。 T.T

Answer 1

我面对mac机器的同样的问题。

从IntellijIDEA运行sbt时，它给出了与问题中提到的相同的错误，但从终端运行它工作正常。

事实证明，intellijidea使用不同于在环境变量中设置的PATH。

欲了解更多详情，请参阅该博客fix PATH environment variable for IntelliJ IDEA on Mac OS X

作为一个解决方案，我创建了一个shell脚本

#!/usr/bin/env bash 
open -a "IntelliJ IDEA" 

，并使其在登录时执行refer this answer to launch an executable at login

嗯，这似乎是一个intellijIDEA问题，因为其他人也面临同样的问题，可以参考here
