Question

所以我正在研究跨平台引导程序，该程序在OSX / Linux上正常工作，但在Windows中返回以下错误消息：

错误：无法创建Java虚拟机。错误：发生了致命异常。程序将会退出。无法识别的选项：-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 Arguments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：/的myapp / _jvm / JRE /../ LIB / tools.jar中; 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，使用双斜线等等无法获得帮助将被赞赏..这里是代码：

   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：

“-cp”和实际的类路径需要是args列表中的单独条目，您当前看起来将它们作为一个以空格分隔的条目。

无法识别的选项：仅在Windows上使用ProcessBuilder的-cp
