我正在尝试使用1.8 Java 64x JDK在IntelliJ中启动dl4j示例。
我按照description
中的说明进行操作现在最后一步不起作用。在开始的时候我会得到数百个例外：
Error:(3,35) java:package org.deeplearning4j.berkeley does not exist
或
Error:(19,38) java:cannot find symbol symbol: class BaseLayer
所以我猜这个问题与导入包有关。我需要补充一点，我是IntelliJ的新手。我是否需要考虑一些特别的事情？ 是否有可能因为使用Java 8而需要重建Maven的pom.xml？
感谢您的任何想法！
P.S。 maven clean install（版本：3.16.0-4-amd64）抛出一些例外：

可能有点晚了，但我有同样的错误......
对我而言，JAVA_HOME变量设置为JRE而不是JDK。 所以将JAVA_HOME变量设置为如下所示：C：\ Program Files \ Java \ jdk1.8.0_112（当然版本不同）
否则会有帮助链接1：http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException 还有一些常见的例子可能会失败...
