Building with Java 11 fails (was "Broken Build")

[lindawr]

Java 8 is required to build the project, but this is not specified in the README. The build fails if using Java 11 (hence my original issue). I switched to Java 8, and it worked. I suppose it should be obvious, but could the README be updated to indicate this? It would save time.

Hello,
The new version https://github.com/axelor/open-suite-webapp/tree/v7.0.0-alpha requires Java 11 whereas former versions required Java 8. The java version required is indicated on https://github.com/axelor/open-suite-webapp/blob/v7.0.0-alpha/build.gradle#L22:

  java {
    toolchain {
      languageVersion = JavaLanguageVersion.of(11)
    }
  }

Adding it explicitely to the README is a good idea, I will transfer the request.
