API Usage

CloverMerge provides a simple API that accepts an array of strings representing the command line arguments and returns an integer result code. The following fragment illustrates use of the API:

import com.cenqua.clover.CloverMerge;

...

String [] cliArgs =
{ "-i", "new.db",  "proj1.db", "proj2.db", "-s", "10s", "proj3.db" }
;
int result = CloverMerge.mainImpl(cliArgs);
if (result != 0)
{            // problem during instrumentation     }

Examples

java com.cenqua.clover.CloverMerge -i new.db proj1.db proj2.db

Merges proj1.db and proj2.db into the new database new.db. A span of zero seconds is used.

java com.cenqua.clover.CloverMerge -i new.db proj1.db -s 30s proj2.db proj3.db

Merges proj1.db, proj2.db and proj3.db into the new database new.db. A span of zero seconds is used for proj1.db, and a span of 30 seconds is used for proj2.db and proj3.db.

The files named coverage.dbxxxx_xxx_xxx are not db files. Please see the clover knowledge base.
You only need to merge files called coverage.db (there should be one per a directory) and not the recording files coverage.dbxxxx_xxx_xxx (there could be hundreds of these)
