Next time, please check Google or another search engine before posting
something like this to the list. Or at least search the Nabble forum.
This is such a common question on the list and yet it is documented in
numerous places which tells me that very few people new to Maven know
how to use a search engine.

Generics were introduced in Java 5 (JDK 1.5). Using source 1.3 in your
pom ensures that source files are compatible with JDK 1.3; this
explicitly disables support for generics.

Hi,
I want to learn maven, and I found this tutorial :

Here is the pom.xml :

The defaults for source/target changed only quite recently.
http://jira.codehaus.org/browse/MCOMPILER-124
mlotfi, what version of Maven are you using? Older ones will use older
plugins and not default to source 1.5.
For older maven versions, you must specify a source version of at least
1.5 to use generics. You can do this in your pom build section (I
included a few other options you can tinker with):
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
<debug>true</debug>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
</plugins>
</build>
Kind regards,
Ben.

Did you look at the compiler configuration options?
http://maven.apache.org/plugins/maven-compiler-plugin/
The default value for source is 1.5
http://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#source
How did you write your pom file?
I suspect you have cut and paste from somewhere that has specified source as 1.3
