2.原因分析

This error is because of maven compiler plugin defaults. Which is currently 1.5. So if you are using java 1.6 for building your project, you are going to face this issue every time you run this command:

3. 解决方案

To solve this issue, you need to make one time update in your pom.xml file. This update is for overriding the default compiler level in maven compiler plugin.

<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>

Update above compiler properties with your desired java version. And place this configuration inside “build” node in pom.xml file like this:

<build>
<finalName>JerseyHelloWorld</finalName>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
</build>

Above change will correct the error.
