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>
