@arina-ielchiieva I don't see why using [maven
embedder](http://maven.apache.org/ref/3.5.2/maven-embedder) is a less
preferable option. Using maven it is possible to create source jars using
standard maven plugin. IMO, it will be easier to modify test UDF project if
necessary and it is still possible to debug and run tests using IDE or maven.
There will be no dependency on a build tool, it is a dependency on an external
jar similar to any other external jar dependency.
