Java Warnings

Enable Java compiler warnings in your build to see them in the pull requests:

In Maven

Enable the showWarnings and showDeprecation flags. Add the -Xlint:all flag to get all warnings. Check the javac manual if you only want to enable specific warnings.

        <encoding>UTF-8</encoding>
        <showDeprecation>true</showDeprecation>

       <compilerArgs>-Xlint:all</compilerArgs>
    </configuration>
</plugin>
