我如何解决有关Maven的构建错误？

Question

我试图用Maven建立一个项目。在存在pom.xml文件的文件夹中，我启动了git bash并使用了“ mvn compile”命令，但是出现以下消息，构建失败：

向maven-compiler-plugin文件中的pom.xml添加配置部分，并将源和目标设置为例如。 1.8。

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