Using Maven ant task to install jar to local repository

Question

At the end of my ant build id like it to call the equivalent of the command line call

mvn install:install-file -Dfile=my.jar -DgroupId=com.company.project -DartifactId=my_project -Dversion=1.0 -Dpackaging=jar -DgeneratePom=true

so that it will add the newly built jar to a maven repository which another project will rely on.

Ive tried using the maven-ant-task and have added the maven-ant-task jar to the ant built project and the following code to the build.xml:

<target name ="minstall" depends="jar">
  <artifact:pom id="maven_install" file="maven_install.xml" />
  <artifact:install file="${out.dir}/my_project.jar">
      <pom refid="maven_install"/>
  </artifact:install> 
</target>

but seem to be missing something as it wont work for me. To begin with i get the error in the build.xml (ant build file) saying

The prefix "artifact" for element "artifact:pom" is not bound.

What am I doing wrong. I am fairly new to ant?

On a realted question what is the purpose of the associated POM file? I would not normally have a POM in this project as it is an ant build

Answer 1

Perhaps maven-ant-task jar is not installed, i.e. not in your ant CLASSPATH. You can follow this instruction for this.
