trip-discovery build.xml fails to compile

[harshil1234]

I am seeing an error while trying to compile trip-discovery jar. So am I doing something wrong.

/usr/local/ant/bin/ant
Buildfile: /Users/harshil/EDH/gis-tools-for-hadoop/samples/trip-discovery/build.xml

BUILD FAILED
/Users/harshil/EDH/gis-tools-for-hadoop/samples/trip-discovery/build.xml:5: 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:
        -/usr/local/ant/lib
        -/Users/harshil/.ant/lib
        -a directory added on the command line with the -lib argument


Total time: 0 seconds

Adding following lines in build.xml fixes it:

<path id="maven-ant-tasks.classpath" path="../lib/maven-ant-tasks-2.1.3.jar" />
  <typedef resource="org/apache/maven/artifact/ant/antlib.xml"
          uri="antlib:org.apache.maven.artifact.ant"
          classpathref="maven-ant-tasks.classpath" />

Thanks.
Aside from that, I see we have not mavenized the samples.

For me ant clean; ant succeeds out of the box. Maybe some configuration or environment affects it.

@harshil1234 What operating system and Ant version do you have?

@climbage Any insights offhand?

Hi Randall,

I am running on Mac OS X Yosemite 10.10.1. Is there something specific that you want me to check in my environment ?

Thanks,
Harshil

[randallwhitman]

Thanks for the OS version. What is your Ant version? Not that I have any real reason to think it makes a difference - I'm making wild guesses. Maybe a colleague with a Mac will be able to try it out.

[harshil1234]

Below is the ant info:
/usr/local/ant/bin/ant -version
Apache Ant(TM) version 1.9.3 compiled on December 23 2013

Thanks,
Harshil

Harshil, would you be able to submit a merge/pull request? In your patch, please adapt the build.xml snippet in your original comment to declare a property for the maven-ant-tasks version rather than hardcoding 2.1.3 inline. Thanks.

Hi Randall, Yes I can do that, one question so I had manually copied this jar file at this location: ../lib/maven-ant-tasks-2.1.3.jar. So you are ok with jar file being copied at this location.

[randallwhitman]

Ideally it would pick up the maven-ant-tasks jar location from the default location in the OS.
Second choice would be a property for the location, which I guess would be necessary anyway to override a default.
