設置maven的編譯器級別

（一）全局設置

首先咱們要在settings.xml文件中找到<profiles>標籤，而後在此標籤內部粘貼以下配置：

<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>

 

 

（二）單個項目單獨設置

若是須要在某個項目中指定編譯級別，能夠在項目的pom.xml文件中配置，以下：

<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>
