The command line is too long. Error: An error occurred while shelling out to javac (error code = 1). Unable to build executable.

I am using mcc to build java classes from .m files The command is following:

mcc -W "java:matlabapi,DefaultClass" -T link:lib -d .\distr\ -w enable:specified_file_mismatch -w enable:repeated_file -w enable:switch_ignored -w enable:missing_lib_sentinel -w enable:demo_license -v -B MatlabClassList

where MatlabClassList is a file with content:

class{Imop_CameraSet_Delete:WaveKit\M_Files\Imop_CameraSet_Delete.m} class{Imop_CameraSet_GetAvailableValue:WaveKit\M_Files\Imop_CameraSet_GetAvailableValue.m} class{Imop_CameraSet_GetAvailableValuesListSize:WaveKit\M_Files\Imop_CameraSet_GetAvailableValuesListSize.m} class{Imop_CameraSet_GetParameterBooleanDefaultValue:WaveKit\M_Files\Imop_CameraSet_GetParameterBooleanDefaultValue.m} class{Imop_CameraSet_GetParameterIntDefaultValue:WaveKit\M_Files\Imop_CameraSet_GetParameterIntDefaultValue.m} class{Imop_CameraSet_GetParameterIntLimits:WaveKit\M_Files\Imop_CameraSet_GetParameterIntLimits.m}

it works if the list is small. However I have 392 classes to create. In this case, I got "The command line is too long. Error: An error occurred while shelling out to javac (error code = 1). Unable to build executable."

If you have large number of files to be compiled, the command executed on the Windows Command prompt will become too long. According to the external link. http://support.microsoft.com/kb/830473

there is a limit (8191) on the number of characters that can be executed on the command prompt.

The work around is to reduce the path of the java files by saving the files in a different path.
