触发Gradle测试时，无法使用commons exec在Java中运行命令行

当我在Intellij中运行Gradle插件的测试用例时，我无法运行“npm-v”

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[]{});
    }
}

当我：
1.使用jar启动应用程序
2.使用IntelliJ触发测试用例（右键单击并运行“MainTest”）
3.运行

gradle clean check

但当我使用Gradle插件运行测试时，一切都变得不安。

输出是

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

对于mac机器，我也面临同样的问题

当从IntellijIDEA内部运行sbt时，它给出了与问题中提到的相同的错误，但从终端运行它效果良好

事实证明，intellijIDEA使用的路径与在环境变量中设置的路径不同

有关更多详细信息，请参阅博客

作为解决方案，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

这似乎是一个intellijIDEA问题，因为其他人也遇到了同样的问题，可以参考

尝试从代码中打印

PATH

环境变量，并比较其有效和无效时的结果。路径是否相同？它是否包含指向

npm

binary的路径？
