And i produce 1 JAR with dependencies included.
But when i generate a ZIP file with Assembly into the zip. i have 2 JAR (MyProject and POI)
this is my Assembly PART:
<assembly>
<id>dist</id>
<formats>
<format>zip</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/LibGenerator</outputDirectory>
<includes>
<include>Vas:Generator:jar</include>
<include>org.apache.poi:poi:jar</include>
</includes>
</dependencySet>
</dependencySets>
</assembly>
How i configure it to produce 1 JAR with Assembly plugIn?
Many Thanks.
