Maven - WEB-INF/lib中不包含的可选依赖项
Maven - WEB-INF/lib中不包含的可选依赖项
提问于 2015-07-16 03:33:46
我有一个maven war模块，它在pom.xml中声明了几个可选的依赖项。在eclipse中，这些选项依赖项显示为构建路径的一部分，这是我所期望的。但是在打包war文件时，maven没有在WEB-INF/lib文件夹中包含这些依赖项，根据maven doc：https://maven.apache.org/guides/introduction/introduction-to-optional-and-excludes-dependencies.html，这是不正确的。你知道为什么会这样吗？
下面是完整的pom.xml

在Maven WAR插件中创建了一个问题，https://issues.apache.org/jira/browse/MWAR-351。
为了解决这个问题，我最终不得不删除
<optional>true</optional> 从ejb war模块中获取，以使其正常工作。对于需要此war模块中的ejb-client的所有其他项目/模块，我最终不得不进行排除，以避免将其依赖项添加到这些项目/模块中(见下文)。
<dependency>

<type>ejb-client</type>

我猜您需要在pom.xml中更改您的plugin尝试添加以下插件
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
</manifest>
</archive>
</configuration>
