Maven Ant Plugin question

[hwpstorage]

Hello,

Sorry for the crossing post.
I tried to use maven to genterate build.xml for ant.
Use command
 mvn ant:ant
will generate build.xml and maven-build.xml, which can be used by Ant.

my problem is
everytime runs ant compile
it will download everything from every repository.

for example, for this jar file parquet-format-1.0.0.jar
I got error, it tries every repository.

in File  maven-build.xml, this is generated via commmand mvn ant:ant

    <mkdir dir="${maven.repo.local}/com/twitter/parquet-format/1.0.0"/>
    <get src="

         ignoreerrors="true"/>

         usetimestamp="false"
         ignoreerrors="true"/>


In the orginal maven pom.xml file
                <dependency>
                        <groupId>com.twitter</groupId>
                        <artifactId>parquet-format</artifactId>
                        <version>1.0.0</version>
                </dependency>


Is there any way to change the generate file maven-build.xml in maven?
is it possible to skip the jar download if the maven.repo.local local
repository already has the jar file?

Thanks a lot
