How to pass a variable from java file to a batch file?-CodePudding

I am trying to pass a variable from java code to batch file. The content of the batch file is-

@echo off 

set rootFolder=%1

set logFolder_Dir=logs

set outputLogsFolder_LocalDir=%rootFolder%\%logFolder_Dir%

set filename=%2

adb shell setprop persist.log.tag V

adb logcat com.harman.prometheusnav > %filename%.txt

pause

I need to pass the value of rootFolder and filename from java code to batch file. Java code to run and close the batch file is -

public static void main(String[] args) throws InterruptedException, IOException {
    ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "logs.bat");
    File dir = new File("C:\\WORKPLACE\\NavSDK\\Prometheus\\Automation\\promta\\src\\test\\resources");
    pb.directory(dir);
    Process p = pb.start();
    Runtime rt = Runtime.getRuntime();
    rt.exec("taskkill /F /IM adb.exe /T");

Is there any other idea to update the batch variable?

CodePudding user response：

According to the documentation for ProcessBuilder, you should simply just add your arguments to the end of the list.

public static void main(String[] args) throws InterruptedException, IOException {
    ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "logs.bat", "C:\RootFoolder", "FileName");
    File dir = new File("C:\\WORKPLACE\\NavSDK\\Prometheus\\Automation\\promta\\src\\test\\resources");
    pb.directory(dir);
    Process p = pb.start();
