Using different Java source version when running Maven2 build

问题

I'm attempting to run my Maven build using the usual:

mvn clean install

I'm getting a whole series of errors that read:

annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)

How do I use -source 5 when performing the build. My JAVA_HOME is pointing to JDK 1.6.

Add this to your pom.xml:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>2.3.2</version>
      <configuration>
        <source>1.6</source> 
        <target>1.6</target>
      </configuration>
    </plugin>
  </plugins>
</build>

It is also documented in the Maven FAQ.

For further information take a look at the Compiler Plugin documentation.

it's in the pom.xml. you should have <source>1.3</source> change it to

<source>1.6</source>
