maven项目不能打包scala代码

在建立maven项目时，遇到问题，只能对java代码的打包。

此问题出现的原因时，在建立项目的时候，建立的时java的项目，后期进行scala的添加，但是在pom.xml中并没有出现scala代码的打包配置，导致只能进行java代码的打包。

解决方法：

在maven文件中，加入scala的打包配置。

            <plugin>
                <groupId>net.alchim31.mavengroupId>
                <artifactId>scala-maven-pluginartifactId>
                <version>3.2.2version>
                <executions>
                    <execution>
                        <id>scala-compile-firstid>
                        <phase>process-resourcesphase>
                        <goals>
                            <goal>add-sourcegoal>
                            <goal>compilegoal>
                        goals>
                    execution>
                    <execution>
                        <id>scala-test-compileid>
                        <phase>process-test-resourcesphase>
                        <goals>
                            <goal>testCompilegoal>
                        goals>
                    execution>
                executions>
            plugin>
