I think it's broken since several months, as the last change on
parquet-tools is around Feb 2020.
The reason why it is not detected by CI is that the build does not run `mvn
clean`, and it seems travis schedule the build in the same machine/sandbox. As
long as no change is made to parquet-tools module, it is not recompiled because
maven considers the classes are already up-to-date.
Here's a snippet that I get from some random travis build of some PR:
```
[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @
parquet-tools ---
[INFO] Nothing to compile - all classes are up to date
```
