LESS:Unable to interpret argument O0

[DhahriHaythem]

when I compile less in eclipse I get this message: Unable to interpret argument O0 - if it is a plugin (less-plugin-O0), make sure that it is installed under or at the same level as less it is the optimization level option that I can not turn off I try it with the command line: lessc style.less > style.ccs works well but lessc style.less -O0 > style.ccs puts the same error message in the css file

How do you resolved it?

[DhahriHaythem]

add these line to lessc file
case 'O0': case 'O1': case 'O1': break;

in switch (arg) statement before the default
