虽然我并不太在意那些繁琐而啰嗦的代码public void execute() throws IOException {
log.info(listToExec.toString());
String[] arrayToExec = listToExec.toArray(new String[0]);
Process process = Runtime.getRuntime().exec(arrayToExec);
InputStream inputStream = process.getInputStream();
Reader inputStreamReader = new InputStreamReader(inputStream);
try (BufferedReader bufferedReader = new BufferedReader(inputStreamReader)) {
String line = null;
while ((line = bufferedReader.readLine()) != null) {
System.out.println(line);
System.out.flush();
}
}
}
但我不明白为什么有时会出现这样的情况： bash 是必需的，其他时候则不需要。
