Hello there! I'm trying to integrate my build.xml with some artifacts
managed by maven. Here's What I've done so far:
<project name="Project Builder"
xmlns:artifact="antlib:org.apache.maven.artifact.ant">
<property file="build.properties"></property>
<path id="maven-ant-tasks.classpath" path="${maven.lib.dir}" />
<typedef resource="org/apache/maven/artifact/ant/antlib.xml"
uri="antlib:org.apache.maven.artifact.ant"
classpathref="maven-ant-tasks.classpath" />
<target name="install-liquid">
<artifact:pom file="${project.dir}/pom.xml" id="mypom" >
</artifact:pom>
<artifact:install
file="${project.dir}/${mypom.artifactId}-${my.version}.${mypom.packaging}"
>
<pom pomrefid="mypompom" />
</artifact:install>
</target>
</project>
But running this task throws an exception
Buildfile: build.xml
install-liquid:
BUILD FAILED

I've checked the source, and MavenProject is null. I did not had the
maven jar on my classpath an thought was that. But I've added it and
the problem persist.
Any idea?
Regards
