@dimense First of all - this is old repository of EclEmma Eclipse plugin, while you're talking about JaCoCo library, which is hosted in another repository.

In your setup (output=file) JaCoCo creates empty exec-file to ensure that output location (destfile) is writable, and writes all the data at the JVM termination (dumponexit=true). So while JVM is not terminated and dump of data is not requested explicitly, it is normal that file stays empty.
