Pessoal, criei o primeiro projeto de "produtos" e retornada um erro onde consegui corrigir aplicando:
<properties>
<!-- compiler settings -->
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
</properties>
Porém, quando fui criar o segundo exemplo do blog, ele retornou o erro:
mvn compile

Então fiz a inclusão da properties como no exemplo anterior e mesmo assim não sai o erro. Como poderia resolver?
