Maven 找不到包，但包在那里-解网

问：

我的Spring Boot项目包含四个模块：一个包装器和其中的三个模块。结构是这样的：

模块：synergpt-wrapper
- 子模块：api
- 子模块：混凝土
- 子模块：核心

下面是 synergpt-wrapper 的 pom.xml：

（我从 pom 文件中删除了 URL，因为 StackOverflow 将它们标记为垃圾邮件）

由于某种原因，该项目不会构建（我使用，因为我需要构建一个可执行的 API jar）。核心包构建正确，我可以在本地 .m2 存储库中找到它。但是在构建 api（依赖于核心）时，Maven 的行为就像核心包不存在一样。它只是指向 api 包的某个类中第一次出现的导入，然后吐出 .正如您在 POM 中看到的，api 依赖于核心，但这应该不是问题。mvn clean install packageiet.synergpt.core.**something**cannot find package iet.synergpt.core.something

最奇怪的是，IntelliJ实际上可以正确地运行所有内容：我只需在SpringBootApplication类上按播放键，所有内容都会被解析并正常运行。问题似乎出在 Maven 中。我已经尝试了一切：删除 .m2、从头开始克隆项目、使 IntelliJ 中的缓存失效，但没有任何反应。

你能帮我吗？

具体的错误消息很好，很有用。此外，显示，而不是告诉我们带有包的 Maven 工件在那里。

您能否分享一下 IDEA 创建的 Run Config 的屏幕截图以及 Maven 返回的确切错误？我假设您正在为父项目（synergpt-wrapper）运行 Maven？不确定为什么必须显式指定 api 的核心依赖项范围？

答： 暂无答案

上一个：使用 JavaFX 依赖项运行 jar 文件时出错

下一个：Javascript + Vue 错误：无法更新滑块的值

Maven 找不到包，但包在那里

Maven can't find package but package is there
