Question

在我们的Web项目中，有几个maven-war-plugin的执行，它们为每个环境生成war文件。我需要为其中一个添加新的依赖项。到目前为止，我们一直在使用叠加层进行此操作，但是这种方法不依赖于drpendencies，因此我们经常最终在不同版本中添加两次相同的库。有没有办法在每个构建中创建多个战争（不是具有不同配置文件的多个构建）和自定义依赖项？

我已经创建了一个示例pom.xml文件

单独使用maven-war-plugin，您无法仅为一次执行添加依赖项。但是在我的工作示例中，我将war插件输出分离到单独的文件夹中，然后使用依赖插件我复制了仅需要＆＃34; dev＆＃34;战争到特定的WEB-INF / lib文件夹...

你看到dev war包含hibernate jar包含传递依赖，而测试war包含eclipselink jar包含。传递依赖。

我认为这不是maven的好用法。但它应该工作。并且它不可扩展..然后你必须管理所有不同战争文件的所有排除列表...... pom.xml可能真的很快就乱了......

<强>建议：也许这是一个好主意，仔细看看应用程序的架构。部署单元应该适用于所有环境。

<强>更新

使用传递依赖性更新了示例......

在maven-war-plugin
