无法使用 intellij 14.1 编译 scala 测试

Question

项目使用scala 2.9

我最大的依赖是：

    <dependency>
        <groupId>org.scalatest</groupId>
        <artifactId>scalatest_2.9.2</artifactId>
    </dependency>

我认为你的依赖不完整，缺少库版本。最简单的是 look it up on Maven Central:

<dependency>
    <groupId>org.scalatest</groupId>
    <artifactId>scalatest_2.9.2</artifactId>
    <version>1.9.2</version> <!-- here -->
</dependency>
