System.getenv()仅在调试IntelliJ插件时才能正常工作

我正在运行IntelliJ 13(在OS X Yosemite上)并尝试让Go IDEA plugin正常工作。当我调试应用程序以试图找出问题所在时,我发现由于某种原因,运行的从属IDEA让我的环境变好了。

通常,当尝试运行涉及go实用程序的任何内容时,会抛出异常。该插件将通过环境变量{/ p>执行go <args>来执行命令

Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(command, goEnv, new File(projectDir));

如果我将go命令更改为go二进制文件的完整路径,则一切正常。然而,在调试时,我不必更改路径,它仍然成功。

该插件有一个action which prints out the environment,可以调用System.getenv()

GoToolWindow toolWindow = this.getGoToolWindow(project);
toolWindow.showAndCreate(project);
toolWindow.clearConsoleView();

String[] sysEnv = GoSdkUtil.convertEnvMapToArray(System.getenv());


toolWindow.printNormalMessage(String.format("%s -> %s%n", "Project dir", projectDir));
for (String env : sysEnv) {
    toolWindow.printNormalMessage(String.format("%s%n", env));
}

正常运行IDEA时,输出:

差异的原因是什么?

根据JetBrains employee,这是因为slave实例是在运行的外部脚本给出的环境下启动的。父进程中的插件不应调用System.getenv(),而应使用EnvironmentUtil
