Maven and JDK requirements in Surefire

[Tibor Digana]

Do you agree to specify these build requirements in surefire POM?

    <prerequisites>
        <maven>3.0.5</maven>
    </prerequisites>

Updating README.txt in GitHub.

Adding configuration of maven-enforcer-plugin with requireMavenVersion=[3.0.5,)

and removing in every POM:

  <prerequisites>
    <maven>${mavenVersion}</maven>
  </prerequisites>

Configuring maven-plugin-plugin:

<requirements>
  <maven>2.2.1</maven>
  <jdk>1.5</jdk>
</requirements>

I will run mvn site site:stage and I will check if every report
has Maven requirements specifying Version 2.2.1.
