Each Maven distribution has various built-in defaults, you can see the defaults
for 3.2.1 here:
https://github.com/apache/maven/blob/maven-3.2.1/maven-core/src/main/resources/META-INF/plexus/default-bindings.xml
The compiler plugin is explicitly set to 2.5.1 unless you override the version
in your pom.xml (I believe this is for stability reasons)
