maven配置全局的jdk和配置局部的jdk

1.设置全局的jdk，在setting.xml文件中的profiles元素下添加如下profile元素

<profile>  
    <id>jdk17</id>  
    <activation>  
        <activeByDefault>true</activeByDefault>  
        <jdk>1.7</jdk>  
    </activation>  
    <properties>  
        <maven.compiler.source>1.7</maven.compiler.source>  
        <maven.compiler.target>1.7</maven.compiler.target>  
        <maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>  
    </properties>   
</profile>  

2.设置局部的jdk，在项目的pom,xml文件中添加如下build元素

<build>  
    <plugins>  
        <plugin>  
            <groupId>org.apache.maven.plugins</groupId>  
            <artifactId>maven-compiler-plugin</artifactId>  
            <configuration>  
                <source>1.7</source>  
                <target>1.7</target>  
            </configuration>  
        </plugin>  
    </plugins>  
</build>
