import-once not working

[GoogleCodeExporter]

Hey guys,

the 'import-once' statement is still not working with wro4j 1.6.3 and neither 
lesscss 1.3.3 nor less4j 1.0.3. Once I change '@import' to '@import-once' the 
compiler throws the following exception:

ERROR PreProcessorExecutor - Cannot ignore missing resource:  
ro.isdc.wro.model.resource.Resource@28f16811[CSS,/less/{insert file or 
directory here}/-once,true]

Obviously the @import statement is found and matched and the compiler tries to 
locate the following '-once' instead of parsing futher.

My less file structure is:

less/
  project.less
  bootstrap-2.3.2/*
  project/
    main.less
    components/*

To have autocompletion etc I would like to use 'import-once' in every component 
to include less mixins and variables. At present, this is not working at all.

The @import-once statement is processed only by LessCssImportPreProcessor (with 
alias: "lessCssImport") which extends the CssImportPreProcessor.

Marking this issue as invalid, since the assumption that the correct processor 
is used is not met.

Feel free to reopen if you don't agree.

Sorry guys, 

I forgot to mention: lessCssImport doesn't work either. Same error message:

0    ERROR PreProcessorExecutor - Cannot ignore missing resource:  
ro.isdc.wro.model.resource.Resource@7dbeb971[CSS,/less/project/components/X/-onc
e,true]

Property file:

preProcessors=lessCssImport
postProcessors=less4j

Could you attach the sample less file?

I've attached a simple test case using the configuration stated before (wro4j 
1.6.3, less4j 1.0.3). 

Property file:
managerFactoryClassName=org.meri.wro4j.nogroups.ConfigurationFreeManagerFactory
preProcessors=lessCssImport
postProcessors=less4j

Same error message:

0    ERROR PreProcessorExecutor - Cannot ignore missing resource:

0    ERROR ExceptionHandlingProcessorDecorator - Failed to process the

Where can I see the implementation of 
org.meri.wro4j.nogroups.ConfigurationFreeManagerFactory ?

Could you try the ro.isdc.wro.manager.factory.ConfigurableWroManagerFactory 
instead?

Ok, thanks for reporting. Will investigate the issue and hopefully will fix it 
for next release.

Fixed in branch 1.6.x.

The cause of the problem: the lessCssImport alias was wrongly associated with 
CssImportPreProcessor instead of LessCssImportPreProcessor. The workaround 
until the next release is available is to override the lessCssImport alias 
explicitly with the LessCssImportPreProcessor.
