Description

We should be able to setup java compiler for examples
to fail on any usage of deprecated APIs.

Something along the lines of:

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>...</version>
  <executions>
    <execution>
      <id>compile</id>
      <phase>process-sources</phase>
      <goals>
        <goal>compile</goal>
      </goals>
      <configuration>
        <compilerArgument>-Xlint:deprecation</compilerArgument>
        <failOnWarning>true</failOnWarning>
      </configuration>
    </execution>
  </executions>
</plugin>
