Norma does not compile on Linux Mint 17.1 LTS (Rebecca)

[sauliusg]

By default, Maven tries to compile the source using Java 1.3 source compatibility, not the 1.5 as required:

saulius@kolibris ~> svn co https://github.com/petermr/norma.git/trunk norma
saulius@kolibris ~> cd norma
saulius@kolibris norma/ > mvn clean compile
...
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project norma: Compilation failure: Compilation failure:
[ERROR] /home/saulius/src/norma/src/main/java/org/xmlcml/norma/json/BibSource.java:[28,20] error: generics are not supported in -source 1.3
...

A workaround found:
-- add the following to the "pom.xml" file:

org.apache.maven.plugins
maven-compiler-plugin
2.3.2

1.6
1.5

saulius@kolibris norma/ > svn diff pom.xml

After this, 'mvn clean compile' builds the project sucessfully.

P.M.-R. suggests that the problem might be in the parent POM which is missing on my machine.
