Throw error when webpack entry is configured and package individually is true

[ceilfors]

This is a Feature Proposal

Description

Context: When package individually is set to true, webpack entry should not be configured at all. This is currently the expected behaviour. It is however not explicit enough to the plugin user and it will fail with some other error.

Proposal: Throw an error when webpack entry is configured and package individually is set to true.

• Support webpack dynamic requires (injected requires) #266. See discussion here.
