Maven 想法插件无法解决本地依赖关系


我创建了一个Maven(Java)项目,其中包含三个Maven子项目module1-3。module2依赖于module1,而module3依赖于module2和module1。

在最初的构建中,module1和module2是多个项目之间共享的通用模块,module3是包含其他两个模块的最终程序。所有模块最终都编译成一个uber-jar以分发给最终客户。

从命令行中,这可以很好地构建和运行,但在导入IntelliJ后,它无法正确解析本地依赖关系。IntelliJ似乎使用了idea:idea目标进行导入,并在我的测试用例中运行idea:idea给出了以下输出,尽管最终获得了构建成功,但显然存在解决问题的问题。

将项目导入IntelliJ后,所有跨模块引用都显示为未解析的符号。

此测试案例的完整源代码位于:https://github.com/hutch31/maven-intellij-plugin-dep

让IntelliJ在Maven子项目中找出这些引用是否需要缺少/额外的步骤?

我正在使用Maven 3.6.3和IntelliJ 2021.1。IntelliJ的集成Maven也是3.6.3版本。

编辑:我尝试更改父模块中模块的顺序,并向子模块添加父标签,这不会影响操作。我已经更新了存储库以反映原始代码的状态,其中模块 3 具有父标记,但模块 1 和模块 2 没有(因为它们是通用代码)。

在命令行上,我使用“mvn clean test”构建并运行。我还添加了一个Maven“编译”配置,尽管报告了错误,该配置仍能正确构建。

maven idea插件早就被弃用了:

https://maven.apache.org/plugins/maven-idea-plugin/

避免使用它。

我相信我已经弄清楚了测试用例中的问题所在,即 mod1/mod2/mod3 的软件包规范与文件路径不匹配。将文件从 src/main/java/org/ghutchis/module1.java移动到 src/main/java/org/ghutchis/mod1/module1.java修复了 IntelliJ 对测试用例的构建问题(尽管遗憾的是,不是原始问题)。

更新后的 Java 代码已推送到 Github 进行检查。
