maven java项目中如何配置pom文件和TeamCity构建依赖模块？

Question

我有由两个模块组成的项目。 其中之一被认为是主要的。 所以第二个取决于第一个。 此外，我应该为模块生成 javadoc jar 文件。 输出应该是四个 .jar 文件：2 个模块 jar 文件和两个 javadoc jar 文件。

在本地，要生成两个 jar 文件，我应该多次重复这些步骤（我不知道为什么）：

1. 构建第一个并安装到本地 Maven 存储库。

2. 然后我可以建立第二个。

没有安装第一个模块，我无法实现打包阶段，因为当我测试第二个模块时，它找不到第一个模块的 jar 文件。

我可以通过一个构建过程完成所有这些步骤吗？

我拥有的 POM：

Answer 1

您只需在父项目上调用mvn clean install 。 它将以正确的顺序构建两个模块。

Answer 2

我找到了解决方案。 收到错误是因为 mainmod 模块仅可用于测试范围<scope>test</scope> secondmod 模块。 然后我添加了具有相同 artifactId、groupId 和 version 的新依赖项，但分配了编译范围。 当然，它向我展示了关于重复的警告。 但是，它解决了问题。 谢谢大家！
