Does anybody have favorite articles or example projects for using buildSrc for handling build logic?

I've just started doing this. First motivation was to generate json schema from kotlin classes during the build. I have a buildSrc that exposes a task that searches the classpath for classes with a n annotation and then generates JSON schema from them. Ive started making some primative 'dsl' for builds -- things that are not quite real 'tasks' but more complicated then a function call. I have added a major hack to work around stale local dependencies and version numbers. In a common plugin, it registers a task to all library builds that generate a versions.properties file that maps a project structure to the dependancy notation + version. Then the same plugin ..... when applied to a downstream build reads the versions file and creates the exact version dependency and artifact IDs This allows me to do something like this: dependencies { compile depends( "project-dir:sub-dir" ) } and this turns into the right compile "whatever-the-group-id-is:the-actual-artifact-id:the-exact-version" These are collected in a directory tree per build (multiple sub-projects) and merged into one big directory that contains the properties files and the actual published artfacts -- This simulates what I have the CI server doing (team city) where multiple chained dependent builds get their artifacts from specific upstream builds, tracking the version numbers. THere is certianly a better way to do this, but I have tried too many worse ways that I ended up with this --
