Answer 1

Add the maven-compiler-plugin to your build:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
</plugins>
</build>

Answer 2

There's an "easier" way to accomplish this, without having to paste the same snippet all over your modules. You can set up a reactor and then you refer to it from all the other modules, like this:
<parent>
<groupId>com.foo.bar</groupId>
<artifactId>reactor</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
In the pom file of your reactor you have to put this:
<packaging>pom</packaging>
To let maven know that it's not a jar/war, etc.
Hope it helps
