Ant Task: Nullpointer Exception
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
java.lang.NullPointerException

at org.apache.tools.ant.launch.Launcher.main(Launcher.java:104)
Total time: 0 seconds
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

Actually fixed this, by using pom inside the <artifact:install>
instead of using pomrefid.
Anyway, I started using <artifact:mvn> instead, but its downloading
all dependencies everytime. Not using my local repository. Why is
that?
