Answer 1

“错误：泛型是不支持的-source 1.3”

即时猜测你的代码使用泛型和编译器被告知使用的Java 1.3不支持这样的。

编辑： 您可能必须至少使用Java 1.5的

<project> 
[...] 
    <build> 
    [...] 
    <plugins> 
    <plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>2.3.2</version> 
    <configuration> 
     <source>1.5</source> 
     <target>1.5</target> 
    </configuration> 
    </plugin> 
    </plugins> 
    [...] 
    </build> 
[...] 
</project> 

Answer 2

添加到您的Maven POM：

<build> 
    [...] 
    <plugins> 
     <plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-compiler-plugin</artifactId> 
     <version>2.3.2</version> 
     <configuration> 
      <!-- set compliance level here --> 
      <source>1.6</source> 
      <target>1.6</target> 
     </configuration> 
     </plugin> 
    </plugins> 
    [...] 
</build> 

BTW，Maven的当前版本假设1.5的默认合规水平。也许你应该升级到当前的Maven版本。
