include maven-ant build libs in eclipse java project -

i struggling maven-ant build eclipse.

i did work below steps.

• [gui] new java project
• add build.xml in project top folder
• run ant file , succeed!
• trying code, somehow auto completion not work.(guessing eclipse can not read maven-ant dependency.path)

so tried.

• add ~/.m2/repository in build path external class folder - not work - looks weird me include whole folder. current project, need little libraries, has whole libraries uses in other projects.
• add builders build.xml want eclipse java project run ant build files automatically - not work neither.

how can add maven-ant libraries properly? sharing experiences , answers xd

=========== information ====================

this build.xml.

and project looks like.

src -- source codes (includes hibernate.cfg.xml) classes -- compiled classes data -- logs , queries build.xml 

fyi, doing book named [[harness hibernate]] written james elliot o'reilly.

thanks again b

for trying do, need filesetid , versionsid="dependency.versions" in declaration of:

 <artifact:dependencies filesetid="dependency.fileset" versionsid="dependency.versions" 

then add copy task so:

 <copy todir="${lib.dir}">    <fileset refid="dependency.fileset" />    <mapper classpathref="maven-ant-tasks.classpath"       classname="org.apache.maven.artifact.ant.versionmapper"       from="${dependency.versions}" to="flatten" />  </copy> 

the to="flatten" flaten dependencies single folder, can include folder on classpath of eclipse project or wherever need it.
