Maven YUI Compressor：聚合后压缩

Question

Can I setup Maven YUI Compressor for compression files after aggregation, because I want to exclude "sources" directory, which contain files for aggregation and then compress aggregated files.

For example I have some .js-files inside of /js/sources/mylib/ and all this files merged into one file /js/mylib.js while yui-compressor aggregation stage. In pom.xml I configure yui-compressor to exclude whole /js/sources/ and compress files only within /js library, but yui-compressor execute "compress" goal before aggregation, so I have uncompressed merged files. And I need to fix this somehow

Answer 1

Can we turn it around and say: Aggregate after compression? If so, I had the same issue and with the following it worked out for me.

The trick seemed to be to put the output file in the target dir instead of in the source. That way you can include files that got minified in the aggregation.

Files that were already minified I then approach through the basedir var.

          <removeIncluded>false</removeIncluded>
          <includes>
              <!-- these exist only in target dir. the original was json2.js & bootstrap.tabs.js -->
              <include>**/bootstrap-tabs-min.js</include>
              <include>**/json2-min.js</include>
              <!-- use originals for the ones already minified -->
              <include>${basedir}/src/main/webapp/js/backbone-min.js</include>
          </includes>
          <output>${project.build.directory}/${project.build.finalName}/js/test.js</output>
        </aggregation>
    </aggregations>
  </configuration>
