Configuration Elements
| Element | Default value | Documentation |
| outputPath | ${project.build.directory} |
The directory in which the compiled CSS files will be placed. |
| inputPath | src/main/sass |
The directory from which the source .scss files will be read. This directory will be traversed recursively, and all .scss files found in this directory or subdirectories will be compiled. |
| includePath | null |
Additional include path, ';'-separated |
| outputStyle | nested |
Output style for the generated css code. One of nested, expanded, compact, compressed. Note that as of libsass 3.1, expanded and compact result in the same output as nested. |
| generateSourceComments | false |
Emit comments in the compiled CSS indicating the corresponding source line. The default value is false. |
| generateSourceMap | true |
Generate source map files. The generated source map files will be placed in the directory specified by sourceMapOutputPath. |
| sourceMapOutputPath | ${project.build.directory} |
The directory in which the source map files that correspond to the compiled CSS will be placed |
| omitSourceMapingURL | false |
Prevents the generation of the sourceMappingURL special comment as the last line of the compiled CSS. |
| embedSourceMapInCSS | false |
Embeds the whole source map data directly into the compiled CSS file by transforming sourceMappingURL into a data URI. |
| embedSourceContentsInSourceMap | false |

| inputSyntax | scss |
Switches the input syntax used by the files to either sass or scss. |
| precision | 5 |
Precision for fractional numbers |
| enableClasspathAwareImporter | false |
Enables classpath aware importer which make possible to @import files from classpath and WebJars. For classpath resources use @import 'path/to/resource/in/classpath';. For WebJar resources a shortcut can be used: @import '{package}/{path}'; imports resource META-INF/resources/webjars/{package}/{version}/{path}. |
