你好，我尝试在Eclipse中运行以下命令代码：
"DIR \""+DEV_HOME+"\\src\"\\*.java /b /s >> \""+DEV_HOME+"\\bin\\javaFiles.txt\""
翻译后的内容：
明确来看，它是这样的：
DIR "D:\Thomas\Dokumente\Daten\workspace\WBRLight\src"\*.java /b /s >> "D:\Thomas\Dokumente\Daten\workspace\WBRLight\bin\javaFiles.txt"
但我收到了以下错误信息：
java.io.IOException: Cannot run program "dir": CreateProcess error=2, Das System kann die angegebene Datei nicht finden
at java.lang.ProcessBuilder.start(ProcessBuilder.java:1041)
at java.lang.Runtime.exec(Runtime.java:617)
at java.lang.Runtime.exec(Runtime.java:450)
....
当我在 cmd 窗口中尝试使用这段代码时，它可以正常运行。 我的代码：
public void run_cmdLine(String command) {
try {
Runtime rt = Runtime.getRuntime();
BufferedReader input = null;
Process pr = null;
pr = rt.exec(command);
input = new BufferedReader(new inputStreamReader(pr.getInputStream()));
String line = null;
while ((line = input.readLine()) != null) {
System.out.println(line);
}
int exitVal = pr.waitFor();
System.out.println("Exited with error code " + exitVal);
} catch (Exception e) {
System.out.println(e.toString());
e.printStackTrace();
}
}
