在 Java 中運行 shell 腳本文件時出現 IoException

Question

我需要在 java 中運行 shell 腳本。 該腳本接受兩個參數作為參數，第一個是名稱，第二個是目錄路徑。

我在本地機器上使用 Windows 作為操作系統。

下面是我試圖運行的代碼：

ProcessBuilder processBuilder = new ProcessBuilder("D:\\temp\\script\\create_script.sh", name, sourceDir);     
       try {
            Process process = processBuilder.start();
            StringBuilder output = new StringBuilder();
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(process.getInputStream()));

            String line;
            while ((line = reader.readLine()) != null) {
                output.append(line + "\n");
            }

            int exitVal = process.waitFor();
            if (exitVal == 0) {
                System.out.println("Success!");
                System.out.println(output);
                System.exit(0);
            } else {
                //abnormal...
            }

        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

上面的代碼給出了以下錯誤：

2021-05-12 22:08:47.383  INFO 10600 --- [nio-8090-exec-1] o.s.web.servlet.DispatcherServlet        : Completed initialization in 1 ms
java.io.IOException: Cannot run program "D:\temp\script\create_script.sh": CreateProcess error=193, %1 is not a valid Win32 application
    at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1128)
    at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1071)

有人可以幫我解決丟失的部分嗎？

感謝您的所有幫助！ 提前致謝！

Answer 1

If you are using Windows, the problem might be that you are trying to run a Linux shell script ( .sh ), hence Windows doesn't really appreciate that. You can either translate Linux shell script into Windows bash script or try to run your program again on a Linux OS, which I would recommend the latter.

下面的代碼對我有用！

ProcessBuilder processBuilder = new ProcessBuilder();
        processBuilder.command("cmd.exe", "/c", "D:\\temp\\script\\create_script.sh);
        try {
            Process process = processBuilder.start();
            StringBuilder output = new StringBuilder();
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(process.getInputStream()));

            String line;
            while ((line = reader.readLine()) != null) {
                output.append(line + "\n");
            }

            int exitVal = process.waitFor();
            if (exitVal == 0) {
                System.out.println("Success!");
                System.out.println(output);
                System.exit(0);
            } else {
                //abnormal...
            }

        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
