ant plugin throwing error for execution of native2ascii task of ant
Hi Guys
As my project supports many languages, so I have various properties file
in utf8 encoding for messages to display on jsps. While building my
project through ant I run native2ascii tag
<native2ascii encoding="UTF8" src="." dest="src/main/resources"
includes="**/*.utf8">
<mapper type="glob" from="*.properties.utf8" to="*.properties" />
</native2ascii>
While using maven to build my project, I am doing the same step using
ant plugin in my pom file like this
<finalName>search-app</finalName>
<plugins>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>generate-sources</phase>
<configuration>
<tasks>
<native2ascii encoding="UTF8" src="."
dest="src/main/resources" includes="**/*.utf8">
<mapper type="glob" from="*.properties.utf8"
to="*.properties" />
</native2ascii>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
but maven is throwing this exception
"[ERROR] BUILD ERROR
[INFO]
------------------------------------------------------------------------
----
[INFO] Error executing ant tasks
Embedded error: Could not create task or type of type: native2ascii.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'native2ascii'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries
implementing the functionality were not found at the time you
yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
task and make sure it contains more than merely a
META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the
needed
libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
- You are attempting to use a task defined using
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.
If instead of native2ascii task, I execute simple copy or delete that
works fine. So assuming there is no issue with ant setting. Any Idea?
Thanks in advance

RE: ant plugin throwing error for execution of native2ascii task of ant
Posted by mvdp <mv...@imc.nl>.
Amit,
native2ascii is an optional task. You are missing a dependency to
ant-nodeps to the plugin (between the artifactId and executions elements).
See below for an example:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<dependencies>
<dependency>
<groupId>ant</groupId>
<artifactId>ant-nodeps</artifactId>
<version>1.6.5</version>
</dependency>
<executions>
<execution>
<id>anId</id>
<phase>aPhase</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<native2ascii encoding="UTF8"
src="."
dest="src/main/resources" includes="**/*.utf8">
<mapper type="glob" from="*.properties.utf8"
to="*.properties" />
</native2ascii>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
