“Failed to create task or type antlib:org.apache.maven.artifact.ant:mvn” error in Ant

Question

Ant build failed to run while running the ant tasks in build.xml. I got the following error in the console:

<         


        

Answer 1

1. Create a lib directory in the root of your project and place the maven-ant-tasks.jar file inside it.
2. Include the import statement in your build.xml

<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" />

The above steps solved my issue. Hope this is helpful to someone in the future.

Alternate solutions,

• You can also place the maven-ant-tasks.jar file under the ANT_HOME/lib folder to solve this issue.
• Or you could have it under the eclipse plugins folder.
  eg. eclipse\plugins\org.apache.ant_1.8.3.v20120321-1730\lib

Answer 2

In my case, i already had the maven-ant-taksk.jar into directory 'eclipse\plugins\org.apache.ant_1.8.3.v20120321-1730\lib'.

I'm using eclipse, so what i needed was, go to Ant Runtime on menu Windows > Preferences > Ant > Runtime, select "Ant Home Entries", click on "Ant Home"button e select the Ant home directory

'eclipse\plugins\org.apache.ant_1.8.3.v20120321-1730\lib'

It worked!
