@skabashnyuk Please ok this - needed to fix some issues with users building plug-ins.

@TylerJewell you have to sign your commit.

[TylerJewell]

@riuvshin Actually, we got confirmation from Eclipse Foundation that committers do not need to sign. Only contributors. The "All checks have failed" issue is a bug with the Eclipse integration and they said that we can ignore it if we know a committer has issued the PR.

[riuvshin]

@TylerJewell yeah I know but this looks like a bug and it's better to sign to pass this validation.

[TylerJewell]

@riuvshin Actually, the previous commit was signed:
14b3ff8 and the error still exists. I think we are safe to merge.

[riuvshin]

@TylerJewell yeah, I see, looks like a bug
