Add new buildscipt classpath dependencies in a plugin

Help/Discuss
1

I would like to simplify the way how a group of other plugins are applied and configured - the meta-plugin would take care of adding required dependencies, applying plugins and providing default configuration. However, I have problem with adding additional dependencies (to the other plugins) on my plugin apply:

InvalidUserDataException: Cannot change dependencies of configuration
    ':classpath' after it has been resolved

Applying gradle files with apply from: before my plugin apply is problematic - those file would be required to get from a jar (e.g. with ant.unjar), some logic would need to be duplicated.

Is there any workaround to allow to add new plugins by the another plugin (on its apply)?

The plugin should depend on the other plugins, not try to modify the buildscript.classpath of the project. So in your plugin project, just add a compile dependency on the other plugins and they will be pulled in too.

Thanks. It sounds very sensible and straightforward :).

Probably I was just fixed with adding dependencies at runtime as in one of my plugins I do it using another buildscript configuration to pass to the underlying process which is executed without having that dependency visible as a classpath dependency in the projects using my plugin.
