Ant-Contrib for loop error

When trying to use Ant-Contrib for loops today, I ran into the error below:

BUILD FAILED
C:\Projects\...\ant\build.xml:200: Problem: failed to create task or type for
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

To fix the error I had to update the Ant-Contrib taskdef resource path from using "antcontrib.properties" to use "antlib.xml" in my Ant build file.

PLAIN TEXT
CODE:
  1. // Remove this line
  2. <taskdef resource="net/sf/antcontrib/antcontrib.properties>
  3. // And replace with this one
  4. <taskdef resource="net/sf/antcontrib/antlib.xml">

According to the Ant-Contrib manual (found in [Ant-Contrib install dir]/docs/manual/index.html) you need to use the "antcontrib.properties" file when you want Ant-Contrib to run with Ant Version 1.5. They even place a warning saying:

Keep in mind that some tasks will not be available to you , such as the <for> task

The confusing part is that on the project page they tell you to use the "antcontrib.properties" file.

Lately I've been looking into optimizing SWF in both speed in file size, below is a list of interesting projects I came across.

Faster compilation

I'm sure there are some projects I missed... Please do let me know about any good ones I omitted.

Installing ANT contrib for Eclipse

A quick step by step guide to installing ANT-contrib for Eclipse (on Windows).

  1. Download ANT-contrib: http://sourceforge.net/projects/ant-contrib/files/
  2. Extract the zip to your harddrive, I extracted it to C:/ant-contrib/
  3. Include ANT-contrib in your ANT build file, so you don't have to set it up every time you create a new project. (See XML below)
  4. All done!

Additional XML in ANT build script:

PLAIN TEXT
XML:
  1. &lt;taskdef resource="net/sf/antcontrib/antcontrib.properties"&gt;
  2. &lt;classpath&gt;
  3. &lt;pathelement location="[full path to ant-contrib jar]"/&gt;
  4. &lt;/classpath&gt;
  5. &lt;/taskdef&gt;

You can exclude files and/or packages from Flex PMD by creating your own rule set, use the "exclude-pattern" tag to exclude files.

PLAIN TEXT
XML:
  1. &lt;ruleset name="myruleset"
  2. xmlns=...&gt;
  3. &lt;description&gt;My ruleset&lt;/description&gt;
  4. &lt;exclude-pattern&gt;.*/some/package/.*&lt;/exclude-pattern&gt;
  5. &lt;exclude-pattern&gt;.*/some/other/package/FunkyClassNamePrefix.*&lt;/exclude-pattern&gt;
  6. &lt;include-pattern&gt;.*/some/package/ButNotThisClass.*&lt;/include-pattern&gt;
  7. &lt;rule&gt;...

Encyclopédie, ou dictionnaire raisonné des sciences, des arts et des métiers (English: Encyclopedia, or a systematic dictionary of the sciences, arts, and crafts) was a general encyclopedia published in France between 1751 and 1772, with later supplements and revisions in 1772, 1777 and 1780 and numerous foreign editions and later derivatives.
