Maven generates javadocs every time you compile your project.
This can be annoying when you want to quickly compile and test your code.
Add this into the <plugins> section of your POM.xml, to skip the javadoc plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.10.3</version>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
