// There is no actual src dir under legacy-worker/ since legacy-worker is built against the
// same sourceSet as fn-api-worker. The reason why legacy-worker has a separated dir is:
// 1. Have one location for editing worker code which is built and tested in two
//    different ways.
// 2. Not have artifacts such as test results and jars write over each other.
// 3. Better compatibility with Intellij since Intellij requires separate content roots.
