Description

I'm not sure if this is an issue with the documentation or the library but using maven-resolver-ant-task in an ant taskdef does not seem to work. I followed the instructions here: https://maven.apache.org/resolver-ant-tasks/index.html to set up my project. I added the pom and build files (see attached). I copied the maven-resolver-ant-tasks.jar into the lib directory of my project.

 

When I try to actually execute the ant build it fails with the error:

The following error occurred while executing this line:
jar:file:/media/psf/Home/Documents/Builder/lib/maven-resolver-ant-tasks-1.2.0.jar!/org/apache/maven/resolver/ant/antlib.xml:36: taskdef A class needed by class org.apache.maven.resolver.internal.ant.tasks.Resolve cannot be found: org/eclipse/aether/resolution/ArtifactResolutionException
 using the classloader AntClassLoader[/media/psf/Home/Documents/Builder/lib/maven-resolver-ant-tasks-1.2.0.jar]

 

Looking at the antlib.xml the offending line seems to be: 

<taskdef name="resolve"              classname="org.apache.maven.resolver.internal.ant.tasks.Resolve"/>

 

I'm not sure what I'm doing wrong here.
