Expected Behavior

ANTLR4 files are generated, the AppVeyor executes the PreBuild event whic is defined in Yaapii.Xml.Xembly.csproj

Actual Behavior

Parser files are not generated. They are included manually now.

Steps to reproduce the behavior

The log given by the failure.

Mention any other details that might be useful

• Maybe the PreBuild event is not triggered by DotNetCoreBuild in cake (simulate this locally?)
• Maybe the Environment variable for Java is not coreectly set, so that we have to adjust our PreBuild event

[ICACLE]

Generated files include a comment to full path of 'Xembly.g' on local HDD.
