無法使用Java ProcessBuilder啟動帶有參數的shell腳本

Question

我正在嘗試使用ProcessBuilder執行帶有命令行參數的shell腳本，此shell腳本調用另外兩個使用此參數的shell腳本。 第一個shell腳本運行正常，但是當第二個腳本啟動時，它返回退出代碼1。

Java程序的ProcessBuilder片段：

//scenario - A string that holds a numerical value like 1 or 2 etc
String[] command2 = {"/bin/bash", "<path to shell script>/runTemporaryTestSuite.sh", scenario};
ProcessBuilder pb2 = new ProcessBuilder(command2);
Process p2 = pb2.start();
BufferedReader br = new BufferedReader(new InputStreamReader(p2.getInputStream()));
String line;
//print - is an object ref of response.getWriter() //
print.println("Output of running "+Arrays.toString(command2)+" is: ");
while ((line = br.readLine()) != null) {
    print.println(line);
}

try {
   int exitValue = p2.waitFor();
   print.println("<br><br>Exit Value of p2 is " + exitValue);
} catch (InterruptedException e) {
   e.printStackTrace();
}

runTemporaryTestSuite.sh

#!/bin/bash
sh <path to script>/clearRegressionResult.sh   (This runs fine)
sh <path to script>/startRegression.sh $1 (This is where the issue occurs)

startRegression.sh看起來像：

SUITE_PATH="./"
java -DconfigPath=${SUITE_PATH}/config.xml -Dscenario=$1 -Dauto=true -jar test.jar

我的輸出：運行[/ bin / bash，/ runTemporaryTestSuite.sh，29]的輸出是：p2的退出值是1

任何解決這個問題的幫助都非常感謝。

認為問題不是你不能用參數啟動shell腳本，我很好奇，我做了一個測試

public class Main {

public static void main(String[] args) throws IOException {
    String[] command = {"/bin/bash", "test.sh", "Argument1"};
    ProcessBuilder p = new ProcessBuilder(command);
    Process p2 = p.start();
    BufferedReader br = new BufferedReader(new InputStreamReader(p2.getInputStream()));
    String line;

    System.out.println("Output of running " + command + " is: ");
    while ((line = br.readLine()) != null) {
        System.out.println(line);
    }
}

這是test.sh腳本

echo Hello im the script, here your args $@

這里輸出

Output of running [Ljava.lang.String;@604e9f7f is: 
Hello im the script, here your args Argument1

我認為只是你的startRegression.sh退出非0狀態（也就是它在某處失敗）並且它有反響，runTemporaryTestSuite.sh也將以非零狀態退出，依此類推，因此消息：退出值p2是1

我現在看到的，

SUITE_PATH =“./”java -DconfigPath = $ {SUITE_PATH} /config.xml [..] configPath將是.//config.xml所以也許你找不到普通文件？ 我可能錯了，希望它有所幫助
