所以我正在开发一个跨平台 Bootstrap ，它在 OSX/Linux 上可以正常工作，但在 Windows 中返回以下错误消息:

Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. Unrecognized option: -cp C:/myapp/realm/bin/Launcher.jar;C:/myapp/_jvm/jre/../lib/tools.jar;C:/myapp/realm/shared/lib/jetty-util-8.1.4.v20120524.jar

如果我打印出我的 ProcessBuilder 参数列表并在命令行上运行这些参数，它将成功运行。命令应该是

C:/myapp/_jvm/jre\bin\java -javaagent:C:/myapp/realm/bin/spring-agent.jar -cp C:/myapp/realm/bin/Launcher.jar;C:/myapp/_jvm/jre/../lib/tools.jar;C:/myapp/realm/shared/lib/jetty-util-8.1.4.v20120524.jar -Xmx256m -Xms200m -Xss128k -XX:+UseBiasedLocking -XX:+UseNUMA -DprocessType=realm -Dcert.framework.license=C:/myapp/realm/license/my.license -Djav a.security.policy=C:/myapp/realm/security/java.policy -Djava.security.properties=C:/myapp/realm/security/java.security -Djava.secur ity.auth.login.config=C:/myapp/realm/security/jaas.conf -Drealm.home=C:/myapp/realm -Duser.dir=C:/myapp/realm/ bin -Djava.endorsed.dirs=C:/myapp/realm/endorsed;C:/myapp/_jvm/jre/lib/endorsed -Djava.ext.dirs=C:/myapp/realm /ext;C:/myapp/_jvm/jre/lib/ext -Dlog4j.configuration=file:C:/myapp/realm/conf/log4j.properties -Dorg.apache.commons.logging.Log=or g.apache.commons.logging.impl.Log4JLogger com.myapp.launcher.ProviderLauncher

我已经尝试在类路径周围放置引号，使用双斜杠等无济于事，我们将不胜感激。这是代码:

   String mainClass = args[0];
   String propFile = args[1];
   FileInputStream fis =new FileInputStream(propFile);
   BufferedReader br = new BufferedReader(new InputStreamReader(fis));
   String line = null;
   ArrayList<String> argList = new ArrayList<String>();
   while((line = br.readLine()) != null){
       if(line.startsWith("#"))
           continue;
       String trimmedLine = line.trim();
       if(trimmedLine.isEmpty())
           continue;
       Matcher m = p.matcher(trimmedLine);
       StringBuffer sb = new StringBuffer();
       while(m.find()){
           String content = m.group(1);
           String envContent = System.getenv(content);
           if(envContent == null || envContent.isEmpty())
               envContent = System.getProperty(content);
           m.appendReplacement(sb, envContent);
       }
       m.appendTail(sb);
       if(!sb.toString().startsWith("\"-") && !sb.toString().startsWith("-") && argList.size() > 0)
           argList.set(argList.size()-1, argList.get(argList.size()-1)+File.pathSeparator+sb.toString());
       else argList.add(sb.toString());
   }

   ArrayList<String> cmdList = new ArrayList<String>();
   cmdList.add(System.getenv("JAVA_HOME") + File.separator + "bin" + File.separator + "java");
   cmdList.addAll(argList);
   cmdList.add(mainClass);
   System.out.println(cmdList.toString());
   ProcessBuilder pb = new ProcessBuilder(cmdList);
   new ProcessBuilder(line);
   File f = new File(System.getenv("MY_DIR") + File.separator + "logs" +File.separator + "provider-console.log");
   if(!f.exists())
       f.createNewFile();
   pb.redirectErrorStream(true);
   pb.redirectOutput(f);
   pb.directory(new File(System.getenv("MY_DIR") + File.separator + "bin"));
   Process p = pb.start();

这是 toStringed cmdList:

最佳答案

“-cp”和实际类路径需要是 args 列表中的单独条目，您目前似乎将它们作为一个条目，用空格分隔。

关于java - 无法识别的选项 : -cp with ProcessBuilder on Windows only，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12592258/
