我从http://alchim31.free.fr/m2e-scala/update-site/安装了Maven Scala支持,并使用Eclipse Marketplace安装了Scala IDE插件。我可以使用mvn compile
命令行构建项目。 Eclipse很好地突出了Scala代码,如果我导入项目它正确识别它的Scala自然。但它并没有将src/main/scala
识别为源文件夹,也没有构建项目。
这是我的pom.xml
:
<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

我做错了什么? pom有问题吗?
作为解决方法,我手动将src/main/scala
设置为源文件夹(右键单击,构建路径|用作源文件夹)。但这并不好,我想找到真正的解决方案,以便在作为Maven项目进行干净导入时正确设置项目。
更新
只需添加add-source
目标+更新Maven项目即可:
<goals>
<goal>add-source</goal>
<goal>compile</goal>
<goal>testCompile</goal>
</goals>

与java-maven-plugin
类似,有addSource
目标可让您定义源和测试目录。你可以这样做:
<plugin>
<groupId>org.scala-tools</groupId>
<artifactId>maven-scala-plugin</artifactId>
<version>2.15.2</version>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>testCompile</goal>
</goals>
</execution>
<execution>
<goals>
<goal>add-source</goal>
<configuration>
<sourceDir>src/main/scala</sourceDir>
<testSourceDir>src/main/test</testSourceDir>
</configuration>
</goals>
</execution>
</executions>
</plugin>

最新插件版本的复制粘贴代码段:
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<version>3.1.3</version>
<executions>
