Jasper,

I also experience similar issues, it comes down to what version of
java you have installed, what version of the plugin you use and what
their respective defaults are. To avoid this I would explicitly state
version's of plugins and also a few other useful properties. I always
but at the least the following in every new project pom;

<project ...
[...]
   <build>
[...]
      <pluginManagement>
[...]
         <plugins>
[...]
            <plugin>
               <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-compiler-plugin</artifactId>
               <version>2.5.1</version>
            </plugin>
[...]
         </plugins>
[...]
      </pluginManagement>
[...]
   </build>
[...]
   <properties>
[...]
      <project.custom.encoding>UTF-8</project.custom.encoding>
      <project.custom.java.version>1.6</project.custom.java.version>
      <maven.compiler.source>${project.custom.java.version}</maven.compiler.source>
      <maven.compiler.target>${project.custom.java.version}</maven.compiler.target>
      <project.build.sourceEncoding>${project.custom.encoding}</project.build.sourceEncoding>
      <project.build.outputEncoding>${project.custom.encoding}</project.build.outputEncoding>
      <project.reporting.outputEncoding>${project.custom.encoding}</project.reporting.outputEncoding>
[...]
   </properties>
</project>
