Good idea to upgrade the scala plugin. But with this change, it does not define a version at all.
I think it would need to be added to the "plugin management" section.

@StephanEwen There already is an entry for scala-maven-plugin in the plugin management section.

[StephanEwen]

Okay, good.
Then I think this is probably good to merge.

@rmetzger Any reservations that the upgrade to the Apache Parent POM v18 has implications on release scripts, etc?

[rmetzger]

I think its fine (as long as we are not merging it to the 1.2 release branch)

@StephanEwen There's no effect to the create_release_files.sh in my opinion.
from v14 to v18, there are some plugins' version upgrade.

[rmetzger]

I think you an not remove the version here. Where does the generated project get the plugin version from?

[shijinkui]

have fix it. Thanks for review:)

[StephanEwen]

Looks good, thanks. merging this...
