Description

The performance of the dependencySet element in the assembly descriptor is significantly worse than achieving the equivalent result by doing an execution of dependency:copy-dependencies and including the target/dependencies folder as a fileSet in the assembly descriptor

replacing:
<assembly>
...
<dependencySets>
<dependencySet>
<outputDirectory>lib</outputDirectory>
</dependencySet>
</dependencySets>
...
</assembly>

with:
<assembly>
...
<fileSet>
<directory>${project.build.directory}/dependency</directory>
<outputDirectory>lib</outputDirectory>
</fileSet>
...
</assembly>

and (in pom.xml):
