解决Maven web 项目 Cannot detect Web Project version. Please specify version of Web Project through ... 的错误

创建maven项目的时候,maven文件头报错：

Cannot detect Web Project version. Please specify version of Web Project through <version> configuration property of war plugin. E.g.: <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <version>3.0</version> </configuration> </plugin>

在project标签内加入以下代码即可解决报错：

<build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
            <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.4</version>
                <configuration>
                    <version>3.1</version>
                </configuration>
            </plugin>
        </plugins>
        <finalName>webserver</finalName>
    </build>
