为了在 IntelliJ 中运行 OptaPlanner 示例，我按照“\optaplanner-distribution-7.23.0.Final”中的“ReadMeOptaPlanner”中的指南进行操作:
- 在 IntelliJ 中将“pom.xml”打开为项目
- 编辑运行配置。
尽管如此，我必须手动更改源版本和目标版本以避免错误:
- 文件 -> 设置 -> 构建、执行、开发部署 -> 编译器 -> Java 编译器 -> 每个模块字节码版本 -> 目标字节码版本 -> 1.8
- 文件 -> 项目结构 -> 模块 -> 源 -> 语言级别 -> 8
但是现在我在构建代码时遇到了 100 个错误，例如:
Error:(24, 62) java: package org.optaplanner.persistence.common.api.domain.solution does not exist Error:(25, 64) java: package org.optaplanner.persistence.xstream.impl.domain.solution does not exist Error:(53, 12) java: cannot find symbol symbol: class SolutionFileIO location: class org.optaplanner.examples.investment.app.InvestmentApp

不幸的是OptaPlanner User Guide 只说:
Open the file examples/sources/pom.xml as a new project, the maven integration will take care of the rest.
谢谢!
- Java:1.8
- IDE:IntelliJ IDEA 社区版 2019.1.3 x64
- OptaPlanner:7.23.0
