Hi Scott,

I found this article which may be useful. Applying the explanation to your use case:

clover.db files should not be kept around between builds and specially not between upgrades of Clover. They should be used for reporting and then discarded.

IncompatibleRegistryFormatException indicates you have a clover.db generated using version 3.1.4 but you are trying to report on it using clover 3.0.2. You should rebuild your project using Clover 3.0.2, rerun your tests and run your report.

first, thanks for responding Felipe,

so this is a clean build, first build, (rm -rf *) clean workspace. the db is not there at all. i am only using the maven clover2 plugin, and it is running on a multi-project (aggregator) maven pom. what is happening appears to be:

during the first pass.

the "test" phase, clover is generating all the individual clover databases in the individual projects (??? using the 3.1.4 interface ???)

then during the same build process (remember this is clean and all i have done is "mvn clean install site") but as the "second pass" via site. then the clover2:aggregator is coming around during "site" lifecycle and trying to put all those little db's together to generate the aggregated clover report for this project.

i think the aggregator goal somehow is still trying to use the old "schema/interface" and it is all ... "what the hell..."

so, next i'm going to have to go take a look at the clover2 plugin source code for the aggregator ....

I am facing the same issue. Were you able to find a solution?
