error: object MultivariateNormalDistribution is not a member of package

完整报错如下：

RunRisk.scala:11: error: object MultivariateNormalDistribution is not a member of package org.apache.commons.math3.distribution
[INFO] import org.apache.commons.math3.distribution.MultivariateNormalDistribution
[INFO]        ^
[ERROR] src/main/scala/RunRisk.scala:185: error: not found: type MultivariateNormalDistribution
[INFO]     val multivariateNormal = new MultivariateNormalDistribution(rand, factorMeans,
[INFO]                                  ^
[ERROR] two errors found
org/apache/commons/commons-math3/3.4.1

 

上述报错的原因是commons-math3版本太低导致的。

解决方案：

pom.xml中commons-math3修改为：
 

<dependency><groupId>org.apache.commons</groupId><artifactId>commons-math3</artifactId><version>3.6.1</version> </dependency>
