Question

无法找到此堆栈跟踪的解决方案我将回答此问题，因此可能对其他人有用。

尝试运行ScalaTest文件时：

import org.scalatest.FlatSpec

class DataTest extends FlatSpec {

  "Number of Links" should "be" in {

    assert(2 === 2)

  }

}

我收到此例外：

java.lang.reflect.InvocationTargetException

    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)

问题是什么？

Answer 1

问题是ScalaTest的版本。项目正在使用：

<dependency>
    <groupId>org.scalatest</groupId>
    <artifactId>scalatest</artifactId>
    <version>1.3</version>
</dependency>

但需要

<dependency>
    <groupId>org.scalatest</groupId>
    <artifactId>scalatest_2.10</artifactId>
    <version>2.2.0</version>
</dependency>

调用ScalaTest时出现java.lang.reflect.InvocationTargetException
