[tycho-user] target-platform-configuration plugin with extensions=true

[Anton Tanasenko <atg.sleepless@xxxxxxxxx>]

Hi,

When updating to 0.21.0 my build started failing with [1].

With trial and error I finally tracked it down to <extensions>true</extensions> on target-platform-configuration plugin entry. It probably got there by some copy-paste while initially configuring parent pom for tycho build. Removing extensions=true solved the problem.

Is it supposed to behave this way?
