[Maven - Java Version] 如何设置Maven的Java版本或者使用不同的JDK版本编译

In pom.xml, defined this maven.compiler.source properties to tell Maven to use Java 8 to compile the project.

1. Maven Properties

Java 8

pom.xml

    <properties>
        <maven.compiler.target>1.8</maven.compiler.target>
        <maven.compiler.source>1.8</maven.compiler.source>
    </properties>

Java 7

pom.xml

    <properties>
        <maven.compiler.target>1.7</maven.compiler.target>
        <maven.compiler.source>1.7</maven.compiler.source>
    </properties>

2. Compiler Plugin

Alternative, configure the plugin directly.

pom.xml

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.6.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

------使用和maven启动使用的jdk不同的jdk编译-----

-----可以在settings.xml或者环境变量中配置JAVA_1_6_HOME这种类型的,然后在

build-->plugins--> <plugin>-->

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
    <configuration>
        <verbose>true</verbose>
        <fork>true</fork>
        <executable>${JAVA_1_6_HOME}/bin/javac</executable>
        <compilerVersion>1.3</compilerVersion>
    </configuration>
</plugin>
