从 Spring 调用命令时，通过 pg_dump 备份 postgresql DB 不起作用

鉴于：

数据库postgresql上Mac。它里面有数据，我可以BackUp从控制台调用/Library/PostgreSQL/10/bin/pg_dump -U db_user_name -w -c -f my_db_name.sql my_db_name，这将在我调用命令的文件夹中创建一个文件my_db_name.sql。

一个任务：

通过 建立定期BackUp数据库Spring。

问题：

以编程方式调用上述脚本时出现错误Файл не найден

问题：

如何实施？似乎问题出在文件/文件夹的访问权限上，但不清楚具体是哪一个以及如何查找。

试过：

我试图指定类型的绝对路径{ПУТЬ_К_ПРОЕКТУ_СПРИНГА}/my_db_name.sql或/Users/myusername/my_db_name.sql- 没有帮助。

编码：

@Scheduled(cron = "0 * * * * *")
fun backUpDb() {
    val executeCmd = "/Library/PostgreSQL/10/bin/pg_dump -U $dbUserName -w -c -f $database.sql $database"

    val runtimeProcess: Process
    try {
        val pb = ProcessBuilder(executeCmd)
        pb.redirectOutput(Redirect.INHERIT)
        pb.redirectError(Redirect.INHERIT)
        runtimeProcess = pb.start()
        val processComplete = runtimeProcess.waitFor()

        if (processComplete == 0) {
            println("Backup created successfully")
        } else {
            println("Could not create the backup")
        }
    } catch (ex: Exception) {
        ex.printStackTrace()
    }
}
