compiling project with jdk1.5 using maven2

i managed to create my project structure using maven2. but when am compiling my project using mvn install getting error generics are not supported in -source 1.3

googled to build my project using jdk1.5 and added build tag

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.myProject</groupId>
  <artifactId>project</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>myapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>3.8.1</version>
    <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
   <plugins>
       <plugin>
           <groupId>com.myProject</groupId>
           <artifactId>project</artifactId>
           <configuration>
               <source>1.5</source>
               <target>1.5</target>
           </configuration>
       </plugin>
     <plugins>
  </build>
</project>

but this is not working.

Any hints?

Add the maven-compiler-plugin to your build:

<build>
  <plugins>
    <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.0.2</version>
    <configuration>
        <source>1.5</source>
        <target>1.5</target>
    </configuration>
    </plugin>
  </plugins>
</build>
