Fatal error compiling: 無效的目 標發行版
 

問題原因：jdk環境和maven配置的jdk不一樣
可將pom.xml檔案中的jdk環境修改為maven配置

修改pom.xml方式如下：

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

或者為

<build>  
    <plugins>  
        <plugin>  
            <groupId>org.apache.maven.plugins</groupId>  
            <artifactId>maven-compiler-plugin</artifactId>  
            <version>2.0.2</version>  
            <configuration>  
                <source>1.8</source>  
                <target>1.8</target>  
            </configuration>  
        </plugin>  
    </plugins>  
</build>
