我正在为许多程序制作一个基于文本的启动器。我正在使用 Runtime.getRuntime().exec("path//to//file.exe"))方法。
该程序将运行，它总是会，但有些行为很奇怪或找不到那里的关键.dll文件。其他人在运行时文本搞砸了等。如您所见，这些都是复杂的游戏，并且使用了许多我不了解的引擎。谢谢！
死亡空间3：屏幕是黑色的，虽然游戏正在运行。仅显示似乎不起作用
MW3：TeknoMW3.exe找不到teknomw3.dll即使它们在同一个文件夹中(启动它通常会使其运行良好(。
无尽空间：文本显示奇怪。退出是 %getuserexit% 或类似于应该和正常显示文本的每个空间。仅在主菜单上出现。
细胞分裂列表：目录正确，找不到指定的文件。病态的突出工作围绕那个。
生化奇兵1：直接崩溃(可能是由于.dll问题，我实际上不知道(
生化奇兵 2：从不运行。 文件已执行但不运行。

程序很可能对其执行上下文有期望。
从您的示例中，每个程序很可能都在运行程序的同一上下文/执行位置启动，这意味着它们找不到所需的库或资源。
不要直接使用 Runtime#exec，而是尝试改用ProcessBuilder。 这将允许您更改进程的执行位置。
例如。。。
String cmd = getDir();
File cmdFile = new File(cmd);
// Maybe check that the cmdFile.exists...;)
File parentFile = cmdFile.getParentFile();
ProcessBuilder pb = new ProcessBuilder(cmd);
pb.directory(parentFile);
pb.redirectError();
Process p = pb.start();
还建议阅读该过程的InputStream，因为当您不;)时，某些过程会感到不安
InputStream is = p.getInputStream();
// This simple reads the contents from the InputStream and discards it
// You could change it to actually dump the output if wanted ;)
while (is.read() != -1);
int exitValue = p.waitFor();
