如何使用 Maven 一步构建多个项目

Question

我有三个项目。前两个项目的 WAR 文件包含在第三个项目的 EAR 中。目前我正在分别为这三个项目执行 Maven 构建。

但我的要求是我只需要构建第三个项目，它应该自动构建前两个项目（WAR 文件），然后它应该构建第三个项目的 EAR。

有谁知道如何实现它。

下面是第三个项目的POM。

Answer 1

谢谢各位， 我在所有项目之上创建了第四个 pom。下面是代码。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>au.com.woolworths.mercury</groupId>
  <artifactId>ReplenishmentR5</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>pom</packaging>
  <modules>
    <module>Replenishment</module>
    <module>ReplenishmentR3</module>
    <module>ReplenishmentR4</module>
  </modules>
</project>

Answer 2

模块中可以参考其他web项目的pom.xml。

<module>../Replenishment</module>

这只有在你将它们与父 pom 关联时才有效
