Custom compiler is not invoked

Hello.

I'm trying to get work on 132.xxx a custom language plugin. Plugin should generate a .java files from custom file.
The problem is that my custom compiler is not executed for my custom file type at all either I do 'Rebuild all' or 'Compile file' on the custom file.
Compiler extends SourceGeneratingCompiler so it should be invoked befor other compiles (as it is written down in JavaDocs)

I've set debug points to every method in Slice2Xxx class but no one is fired.

Could you help me to figure out what happend?

Here is some code:
plugin.xml

    <extensions defaultExtensionNs="com.intellij">
        <fileTypeFactory implementation="org.xblackcat.frozenice.IceFileTypeFactory"/>
        <compilerFactory implementation="org.xblackcat.frozenice.processor.SliceCompilerFactory"/>
 

IceFileTypeFactory:

public class IceFileTypeFactory extends FileTypeFactory {
    @Override
    public void createFileTypes(@NotNull FileTypeConsumer consumer) {
        consumer.consume(IceFileType.INSTANCE, "ice" + FileTypeConsumer.EXTENSION_DELIMITER + "slice");
        TypedHandler.registerBaseLanguageQuoteHandler(
                SliceLanguage.class,
                TypedHandler.getQuoteHandlerForType(IceFileType.INSTANCE)
        );
    }
}

SliceCompilerFactory:

public class SliceCompilerFactory implements CompilerFactory {
    @Override
    public Compiler[] createCompilers(@NotNull CompilerManager compilerManager) {
        compilerManager.addCompilableFileType(IceFileType.INSTANCE);
        compilerManager.addCompiler(new Slice2Xxx());
        return new Compiler[0];
    }
}
 

Slice2Xxx:

public class Slice2Xxx implements SourceGeneratingCompiler {
    public static final GenerationItem[] NO_ITEMS = new GenerationItem[0];

    @Override
    public VirtualFile getPresentableFile(
            CompileContext context,
            Module module,
            VirtualFile outputRoot,
            VirtualFile generatedFile
    ) {
        return null;
    }

    @Override
    public GenerationItem[] getGenerationItems(CompileContext context) {
...
    }

    @Override
    public GenerationItem[] generate(CompileContext context, GenerationItem[] items, VirtualFile outputRootDirectory) {
...
    }

    @NotNull
    @Override
    public String getDescription() {
        return "slice";
    }

    @Override
    public boolean validateConfiguration(CompileScope scope) {
....
    }

    @Override
    public ValidityState createValidityState(DataInput in) throws IOException {
        return TimestampValidityState.load(in);
    }

}
