  Researchers, students and practitioners often encounter a situation when the
build process of a third-party software system fails. In this paper, we aim to
confirm this observation present mainly as anecdotal evidence so far. Using a
virtual environment simulating a programmer's one, we try to fully
automatically build target archives from the source code of over 7,200 open
source Java projects. We found that more than 38% of builds ended in failure.
Build log analysis reveals the largest portion of errors are
dependency-related. We also conduct an association study of factors affecting
build success.
