带有空格和双引号的Java-ProcessBuilder命令参数失败

Question

我正在使用ProcessBuilder运行Windows可执行文件...我需要运行的确切命令是：

"C:\Program Files\CCBU\CCBU.exe" -d"C:\My Data\projects\ccbu\ciccb-report.xls" -tf"C:\Program Files\CCBU\loss-billing-filters.txt"

如果我在命令提示符下运行上述命令，效果很好。

如果我随后以字符串[]数组的形式发出以下StackOverflow post（ProcessBuilder向命令行添加额外引号）中所示的命令和参数，则会失败，因为目录路径中的空格以某种方式将参数打断到CCBU。exe可执行文件：

[log-snippet]
2015-08-31 10:39:08,937 [main] INFO  rpd.primary - C:\Program Files\CCBU\CCBU.exe
logging to the given report's directory
Configuration file is: ./CCBUConfigFile.txt
Running with the following settings:
Report Filepath:       C:\My
Search Terms FilePath: C:\Program

2015-08-31 10:39:08,948 [main] INFO  rpd.primary - STDERR:--------------------
2015-08-31 10:39:08,961 [main] INFO  rpd.primary - 
Warning: parameter Data\projects\ccbu\ciccb-report.xls not recognized. Ignoring

Warning: parameter Files\CCBU\loss-billing-filters.txt not recognized. Ignoring

Error: C:\Program not found or not readable
[/log-snippet]

如果我将数据文件和过滤器移动到一个没有空格的目录路径，这很好：

"C:\Program Files\CCBU\CCBU.exe" -d"C:\Users\n0002501\ccbu\ciccb-report.xls" -tf"C:\Users\n0002501\ccbu\loss-billing-filters.txt" 

问题是，此过程的用户将把文件放在确实有空格的文件夹（目录）中。所以不知何故，我必须让它使用空格。我认为这很简单，但我错过了什么？

我使用本文中的类来处理STDOUT和STDERR的线程：http://alvinalexander.com/java/java-exec-processbuilder-process-2

代码如下：

            // Split the Arguments : 
            // In Eclipse and runtime, the arguments get broken : 
            // The STDOUT from the command shows the Report Filepath
            // and Search Teams FilePath as broken at the 1st space...
            // 
            // Report Filepath:       C:\My
            // Search Terms FilePath: C:\Program
            // 
            // SHOULD BE : 
            // 
            // Report Filepath:       C:\My Data\projects\ccbu\ciccb-report.xls
            // Search Terms FilePath: C:\Program Files\CCBU\loss-billing-filters.txt
            // 
            try { 
                commands.add ( "\"C:\\Program Files\\CCBU\\CCBU.exe\""                      );
                commands.add ( "-d\"C:\\My Data\\projects\\ccbu\\ciccb-report.xls\""        );
                commands.add ( "-tf\"C:\\Program Files\\CCBU\\loss-billing-filters.txt\""   );
                commandExecutor = new SystemCommandExecutor(commands);
                commandExecutor.setLog ( getLog() );

                // DEBUG : Build and printout the commands...
                // 
                lstrCommand = "";
                for ( int theIdx=0; theIdx<commands.size (); theIdx++ ) {
                    if ( theIdx == 0 ) { 
                        lstrCommand = lstrCommand + commands.get ( theIdx );
                    }
                    else { 
                        lstrCommand = lstrCommand + " " + commands.get ( theIdx );
                    }
                    getLog().debug ( SHORT_NAME + " Building Command[] [" + commands.get ( theIdx ) + "]" );
                }

                getLog().debug ( SHORT_NAME + " Running Command[] [" + lstrCommand + "]" );

                result = commandExecutor.executeCommand();

                // get the stdout and stderr from the command that was run
                stdout = commandExecutor.getStandardOutputFromCommand();
                stderr = commandExecutor.getStandardErrorFromCommand();

                // print the stdout and stderr
                getLog().info ( "SystemCommandExecutor - Status Code [" + result + "]" );
                getLog().info ( "STDOUT:--------------------" );
                getLog().info( stdout );
                getLog().info ( "STDERR:--------------------" );
                getLog().info( stderr );
            }
            catch ( Exception ltheXcp ) { 
                getLog().error ( SHORT_NAME + ".runTask () - Error/exception on commands [3-spaces] [" + lstrCommand + "]" );
            }
            finally { 
                commands.clear ();
                stdout = null;
                stderr = null;
                commandExecutor = null;
            }

Jayan，最终有效的代码：

            try { 
                commands.add ( "C:\\Program Files\\CCBU\\CCBU.exe"                      );
                commands.add ( "-dC:\\My Data\\projects\\ccbu\\ciccb-report.xls"        );
                commands.add ( "-tfC:\\Program Files\\CCBU\\loss-billing-filters.txt"   );

                commandExecutor = new SystemCommandExecutor ( commands );
                commandExecutor.setLog ( getLog() );

我所要做的就是去掉所有的双引号，让ProcessBuilder自己处理目录路径。。。

添加不带“双”引号的单个字符串。。

                commands.add ( "C:\\Program Files\\CCBU\\CCBU.exe"                      );
                commands.add ( "-d");
                commands.add ("C:\\My Data\\projects\\ccbu\\ciccb-report.xls"        );
                commands.add ( "-tf");
                commands.add("C:\\Program Files\\CCBU\\loss-billing-filters.txt"   );
                commandExecutor = new SystemCommandExecutor(commands);

ProcessBuilder将负责args的必要处理。

调出评论：

贾扬，你的想法让我思考：以下工作：

 commands.add ( "-dC:\\My Data\\projects\\ccbu\\ciccb-report.xls" );
 commands.add ( "-tfC:\\Program Files\\CCBU\\loss-billing-filters.txt"
