A small package to sync the package.json version with the pom.xml one (i.e. to be used with maven-release-plugin).

$ npm i --save sync-pom-version

In your package.json:

{
  "scripts": {
    "postinstall": "sync-pom-version <path-to-pom>"
  }
}

Or as a global package:

$ npm i -g sync-pom-version
$ sync-pom-version <path-to-pom> <path-to-package-json>
