maven配置全局的jdk和配置局部的jdk

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

[html] view plaincopy
<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> 

设置局部的jdk，在项目的pom,xml文件中添加如下build元素

[html] view plaincopy
<build> 
    <plugins> 
        <plugin> 
            <groupId>org.apache.maven.plugins</groupId> 
            <artifactId>maven-compiler-plugin</artifactId> 
            <configuration> 
                <source>1.7</source>
