I was planning to update the SchemaSpy package from 6.1.1 to 6.2.2, so I updated the version and the hashes, built it with
nix-build -A schemaspy . without errors, but this is what I got when tried to run it:
$ ./result/bin/schemaspy --help no main manifest attribute, in /nix/store/0swkc0rzwd0h22bymhbv5nrkl34k3xva-schemaspy-6.2.2/share/java/schemaspy-6.2.2.jar
Looked up the error, found this Stackoverflow thread, but I’m not familiar with Java or its ecosystem, and based on the release notes since 6.1.1 there weren’t any breaking changes (at least from what I can tell).
