如何在Maven的项目里写scala的代码

 

前提是你的Maven都配置好了

首先创建一个Maven的项目，别在创建项目的时候点击加包的操作

如果你点了，你会发现创建出来的Maven项目是没有src目录的

创建完成把你的pom文件替换成下面的这个：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <plugins>
            <!-- This plugin compiles Scala files -->

            </plugin>
            <!-- This plugin adds all dependencies to JAR file during 'package' command.
            Pay EXTRA attention to the 'mainClass' tag.
            You have to set name of class with entry point to program ('main' method) -->
            <plugin>

                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <mainClass>ScalaRunner</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
 
        </plugins>
    </build>
 
</project>

完成之后你再添加你所需要的依赖

之后便可以在项目中创建scala的代码了
