Build failure cannot build ANTLR parser

[vladistan]

When trying to do build using Maven 3.3.9 I get the following error:

INFO] ANTLR: Processing source directory /Users/vlad/Proj/sonar-xquery-plugin/src/main/antlr3

Hmm... this only happens on freshly checkout build or after doing 'mvn clean'
Just repeating maven command second time completes the build..

Looks like this is caused by building on Java 8. There are two ways to fix this, either to compile with Java 7 or upgrade to Antlr 3.5.2. Unfortunately the later does not work, the error above goes away, but the resulting parser could not parse the XQuery sources.

The two issues below are related to this one:

I'm also facing the same issue.

Any solution to resolve this issue.?

The same issue faced while building. Please resolve it in the next release. Old antlr codebases will be rendered useless with Java 8 and above.
