Example about include only a few files and aggretate it into one file

[matienzar]

Hello,

I don't where to post it, and I post it to an issue.

I've several js files and I only need to compress and aggregate a few ones into a directory. What I've to do it?

I need to do something like this:

directory1

• file1.js
• file2.js
  directory2
  • file3.js
    directoryn
    -filen.js

I only need to compress and aggregate in a single file directory1

Lot of thanks,

Marcial

You can exclude every directory2-n explicitly, but it could be tedious.
I suggest to move directory1 outside src/main/webapp (eg src/main/webapp-ext) and configure the plugin with

  <configuration>
      <warSourceDirectory>${basedir}/src/main/webapp-ext</warSourceDirectory>
      <aggregations>
        <aggregation>
          <removeIncluded>true</removeIncluded>
          <insertNewLine>true</insertNewLine>
          <output>${project.build.directory}/${project.build.finalName}/directory1/all.js</output>
          <includes>
            <include>**/*.js</include>
          </includes>
        </aggregation>
      </aggregations>
    </configuration>

A good is to have an option to include a list of files and mantain the order. Example:

I only need this 3 files about 100 others:

file1js
file2.js
file3.js

file3.js depends on file1.js, file1.js in aggregate must be the first

aggregation keep the ordre if you don't use wildcard

      <includes>
        <include>file1.js</include>
        <include>file2.js</include>
        <include>file3.js</include>
      </includes>

as a side note, I encourage you to take alook at js loader like head.js, LAB.js, requirejs,... to avoid aggregation and order constraint.
