1. Assume you have just forked & cloned https://github.com/liferay/liferay-portal so your local copy is fresh, does not have any additional dependencies downloaded that the build env may need
2. Run ant snapshot-bundle to obtain a fresh bundle

Expected Result: Snapshot bundles is downloaded and extracted successfully.
Actual Result: Build fails with:

Buildfile: /home/tibusz/git/liferay/ce/liferay-portal/build.xml
  [typedef] Could not load definitions from resource org/apache/maven/artifact/ant/antlib.xml. It could not be found.

BUILD FAILED
/home/tibusz/git/liferay/ce/liferay-portal/build.xml:1098: Problem: failed to create task or type antlib:org.apache.maven.artifact.ant:dependencies
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.
No types or tasks have been defined in this namespace yet

This appears to be an antlib declaration. 
Action: Check that the implementing library exists in one of:
        -/home/tibusz/dev/ant/lib
        -/home/tibusz/.ant/lib
        -a directory added on the command line with the -lib argument


Total time: 4 minutes 8 seconds

Background
This is because https://github.com/liferay/liferay-portal/tree/master/lib/development does not have maven-ant-tasks.jar by default. It's downloaded when you run "ant all" by the "setup-libs" task.

Maybe we could include that JAR in the repo permanently.

Workaround: Run ant setup-libs before executing "ant snapshot-bundle".
