java generics and annotations not supported in version 1.3 (travis integration)

I'm trying to integrate my github Java/PHP project with travis-ci environment. This is my travis configuration:

language: java
jdk:
  - openjdk7
  - oraclejdk7
script: mvn test

Below is the output that travis prints:

The output says that I'm using the too old version of java to use annotations and generics. But these are nothing new and they have to be supported somehow (I guess). I've been looking at travis/java docs but found no option about java version (hence I tried to use different jdks). Can anyone point me what should I put into the travis config file?

edit:

following @hertzsprung, I ran mvn help:effective-pom and it returned following output (in fact, neither source nor target attribute are note defined for maven-compiler-plugin - what can I do about it?):
