Java dl4j中的包不存在

我正在尝试使用1.8Java64XJDK在IntelliJ中启动dl4j示例

我完全按照你的指示去做

现在最后一步不起作用了。开始时，我会收到数百个异常，如：

 Error:(3,35) java:package org.deeplearning4j.berkeley does not exist 

或

所以我想问题与包裹的导入有关。我需要补充一点，我是IntelliJ的新手。我需要考虑一些特别的东西吗？ 是否可能因为使用Java 8而需要为Maven重建pom.xml

谢谢你的建议

另外，maven clean install（版本：3.16.0-4-amd64）引发了一些异常：

可能有点晚了，但我也犯了同样的错误

对我来说，JAVA_HOME变量被设置为JRE而不是JDK。 因此，将JAVA_HOME变量设置为如下内容：C:\Program Files\JAVA\jdk1.8.0_112（当然，版本会有所不同）

否则，将显示帮助1的链接：

还有一些常见的例子说明了为什么它可能会失败…

您所说的最后一步是什么意思？在您自己的项目中使用DL4J：配置POM.xml文件？开始示例。运行项目..我测试了项目，它对我有效。在导入到intellij之前，请确保“mvn clean install”命令已成功，并且您正在将其作为maven项目导入。使用“mvn clean install”语句时，我确实遇到一些错误。[错误]无法执行目标org.apache.maven.plugins:maven enforcer插件：1.4.1:ProjectDeepLearning4J上的强制（强制默认）示例父：某些强制规则失败。查看上面解释规则失败原因的特定消息。->[Help 1]您是否“查看上面解释规则失败原因的特定消息”？请将maven命令输出的最后一块以及maven版本添加到您的帖子中。
