Summary: Reduce warnings in Java 7/Java 8 build
Key: LUCENE-6740
URL: https://issues.apache.org/jira/browse/LUCENE-6740
Project: Lucene - Core
Issue Type: Improvement
Reporter: Uwe Schindler
Assignee: Uwe Schindler
This is a overview issue about improvements to reduce warnings during the
build. Since we moved trunk to Java 8 and branch_5x to Java 7, there were
introduced some additional warnings, mostly in generated code.
ANTLR4 does automatically add the needed @SuppressWarnings, but jflex does not.
There are also some rawtypes warnings, which changed in Java 7 (before Java 7
there were only "unsafe" warnings, now you need both.
I enabled the Warnings tracker in Policeman Jenkins, we can therefore very
easily check the warnings: e.g. on trunk:
http://jenkins.thetaphi.de/job/Lucene-Solr-trunk-Linux/ (see diagram on the
right), you can click on it, e.g.
