java - 迁移到 Spring Boot 后 ProcessBuilder 找不到可执行文件

Question

我有一个使用 Quartz 作为任务运行的 java 类(作为 Java CMS 中的插件)。我现在将其从 CMS 移至 Spring Boot (v1.0.2) 项目，并使用 @Scheduled 注释。

问题是 ProcessBuilder 报告缺少可执行文件，但 File().exist() 返回 true。

它是 FreeBSD 9.2 上相同的 Java 版本 OpenJDK 7、相同的应用程序容器 (Tomcat 7)。

测试代码如下:

package test;

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;

@Service
public class SchedulerTest {

    @Scheduled(fixedDelay=1800000, initialDelay=5000)
    public void test() {

        if ((new File("/usr/local/bin/exiftool")).exists()) {
            System.out.println("Found exiftool");
        }
        else {
            System.out.println("Did not find exiftool");
        }

        List<String> args = new ArrayList<String>();
        args.add("/usr/local/bin/exiftool");
        args.add("-n");
        args.add("-S");
        args.add("-DateTimeOriginal");
        args.add("/image/TEST.JPG");
        Process proc = null;
        try {
            proc = new ProcessBuilder(args).start();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        if (proc != null) {
            System.out.println("ExifTool output: " + proc.getOutputStream());
            proc.destroy();
        }
    }

}

输出是:

可能是什么问题？我的猜测是从 Quartz 迁移到 @Scheduled。我也尝试过创建 cutsom bean 并将线程池设置为 2，但没有任何运气。

也许是文件格式问题(不是真正可执行的？)。例如。看到这里"aapt" IOException error=2, No such file or directory" why can't I build my gradle on jenkins? .
