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,module3同时依赖于module2和module1。
在最初的构建中,module1和module2是多个项目之间共享的公共模块,module3是合并其他两个项目的最终程序。所有模块最终都被编译成一个uberjar,分发给最终客户。
从命令行生成并运行得很好,但是在导入intellij之后,它无法正确解析本地依赖关系。看起来intellij使用idea:idea goal 用于导入和运行idea:idea on 我的testcase给出了以下输出,尽管最终获得了构建成功,但它显然在解决这些问题时遇到了问题。
将项目导入intellij后,所有跨模块引用都显示为未解析的符号。
此测试用例的完整源代码位于:https://github.com/hutch31/maven-intellij-plugin-dep
要让intellij在maven子项目中找出这些引用,是否需要缺少/额外的步骤?
我使用的是maven 3.6.3和intellij 2021.1。intellij的集成maven也是3.6.3版。
编辑:我尝试更改父模块中模块的顺序,并将父标记添加到子模块中,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module3有一个父标记,而module1和module2没有(因为它们是公共代码)。
在命令行上,我使用“mvn clean test”构建和运行。我还添加了一个maven“compile”配置,尽管报告了错误,但它仍能正确构建。

maven idea插件长期以来一直不受欢迎:
https://maven.apache.org/plugins/maven-idea-plugin/
避免使用它。

我相信我已经找出了testcase中的问题所在,即mod1/mod2/mod3的包规范与文件路径不匹配。将文件从src/main/java/org/ghutchis/module1.java移到src/main/java/org/ghutchis/mod1/module1.java修复了intellij在测试用例中的构建问题(不过,遗憾的是,这并不是最初的问题)。
更新后的java代码已被推送到github进行检查。
