你有类似下面的东西来指定maven编译器插件使用的java版本吗？

<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>

更短的版本

<project>
    <properties>
        <maven.compiler.source>1.5</maven.compiler.source>
        <maven.compiler.target>1.5</maven.compiler.target>
    </properties>
....
