Use wildcards in a Google Closure Compiler Ant build - ant

Question

Is it possible to use wildcards to select multiple files instead of specifying each one with a <file> tag?
Currently I am doing this:
<jscomp compilationLevel="simple" debug="false" output="build.js">
<sources dir="${basedir}/source">
<file name="foo.js" />
<file name="bar.js" />
</sources>
</jscomp>
I tried using <fileset> but <sources> doesn't support it:
<jscomp compilationLevel="simple" debug="false" output="build.js">
<sources dir="${basedir}">
<fileset dir="source">
<include name="**/*.js" />
</fileset>
</sources>
</jscomp>

Answer 1

Looking at the source for the compiler I believe (not tested) that it supports an Ant path as an alternative to the filelist it originally supported. A patch was made to add this. There have been attempts to change from a filelist to a fileset, but the problem there is that filesets are not ordered.
Based on the patch submission, you would do something like this. This example shows a mix of a filelist and a fileset being used:
<path id="ui.js.fileset">
<fileset dir="source">
<include name="**/*.js" />
</fileset>
</path>
<path id="app.js.fileset">
<filelist dir="${js.dir}/app/">
<file name="app.core.js"/>
<file name="app.foo.js"/>
</filelist>
<path refid="ui.js.fileset" />
</path>
<jscomp compilationLevel="simple" debug="false" output="build.js">
<path refid="app.js.fileset" />
</jscomp>
It appears the documentation hasn't been updated to reflect the availability of this option, but it does say there "New features are added occasionally, the source for the task may be the best documentation."
