benchmarksAnalyzer is built with bootstrap KGP and snapshot compiler. Currently the former is K1, while the latter is K2. As a result, the build fails because K2 compiler needs -Xfragment-sources argument, while K1 uses -Xcommon-sources. So KGP passes the latter, while the compiler expects the former. Fix this by forcing KGP to use K2 for benchmarksAnalyzer.
