[axelfontaine]

Thanks for pointing this out! Fixed.

[krotscheck]

You're welcome!

[rreimann]

@axelfontaine are there any plans on a short-term 2.2.x release containing this fix?

[axelfontaine]

Yes, probably by the end of this week as I'll be on holiday after that.

[sanchitbahal]

@axelfontaine Has this already been released? I am using flyway-maven-plugin v2.2 which still seems to have problem with Maven 3.1.

[axelfontaine]

Not yet. I was on holiday. Should be out soon though.
