The new Maven Project, which is the default JDK 1.5

Modified in two ways.

1. Modify conf / settings.xml under maven directory for the overall situation.

In the profiles node is added:

<profile>

    <id>jdk-1.7</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>

JDK version here can be modified.

Modify and then create a new project:

2. modify the pom.xml for the project file, and then use the maven command line (mvn clean, mvn package), you can get to specify jdk version of the compiler jar package.

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<configuration>

<source>1.7</source>

<target>1.7</target>

<encoding>${file_encoding}</encoding>

</configuration>

</plugin>

</plugins>

</build>

After modifying pom.xml, and execute mvn clean mvn package, and then view the generated class file is generated by what version of the JDK.
