wro4j less-compiler也编译.css文件

Question

我正在使用wro4j 1.7.3和less4j/lesscss-compiler。

preProcessors=less4j,
yuiCssMin,googleClosureSimple

在我的wro.xml中，我有如下内容：

<group name='css'>
    <css>/resources/css/base.css</css>
</group>

在编译时，我会得到一个错误，因为wro4j将我的*.css-file也当作*.less-file来处理。

Exception occured while processing: ro.isdc.wro.WroRuntimeException: 
Could not compile    less. 1 error(s) occured:
ERROR 437:1 missing EOF at '}' in stylesheet (which started at 23:1)
, class: ro.isdc.wro.WroRuntimeException,caused by:     
com.github.sommeri.less4j.Less4jException Could not compile less. 1 error(s) occured:
ERROR 437:1 missing EOF at '}' in stylesheet (which started at 23:1)

当使用lessCSS时，而不是less4j，错误原因更好地显示出来：

MEZ: [ERROR] Exception occured while processing: ro.isdc.wro.WroRuntimeException: Could  
not execute the script because: 
{
"type": "Runtime",
"message": "error evaluating function `saturate`: Cannot find function toHSL in object   
[object Object].",
"filename": null,
"index": 11114.0,
"line": 754.0,
"callLine": null,
"callExtract": null,
"stack": null, 
"column": 17.0,
"extract": [
".img-saturate{ ",
"   -webkit-filter: saturate(500%);",
"   -moz-filter: saturate(500%);"
]
}, class: ro.isdc.wro.WroRuntimeException,caused by:  Could not execute the script   
because:

"extract": [
".img-saturate{ ",
"   -webkit-filter: saturate(500%);",
"   -moz-filter: saturate(500%);"
] 
}

更改处理器顺序无济于事：

preProcessors=yuiCssMin,googleClosureSimple
postProcessors=less4j

错误仍然存在。

是否存在这样的可能性，比如wro4j，它不应该将带有css的文件结尾视为更少。

谢谢亚历克斯,

通过使用less4j.less，less处理器将只扫描更少的文件：

preProcessors=less4j, yuiCssMin,googleClosureSimple
#postProcessors=less4j

然而，事后我找到了错误的真正原因。css文件中缺少结尾大括号。通过添加撑杆，所有工作都很好！
