Question

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，那些选项依赖项显示为构建路径的一部分，这正是我所期望的。但是在打包war文件时，maven不包括WEB-INF / lib文件夹中的那些依赖项，根据maven doc：https://maven.apache.org/guides/introduction/introduction-to-optional-and-excludes-dependencies.html这不正确。知道为什么会这样吗？

以下是完整的pom.xml

Answer 1

我想你需要在pom.xml中改变你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>
      </plugin>

为此创建了一个Maven WAR插件问题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模块开始工作。对于需要来自此war模块的ejb-client的所有其他项目/模块，我最终必须进行排除以避免将其依赖项添加到这些项目/模块中（参见下文）。

  <dependency>
    <groupId>com.boss</groupId>
    <artifactId>Boss</artifactId>
    <version>1.0</version>
    <type>ejb-client</type>
    <exclusions>
        <exclusion>
            <groupId>*</groupId>
            <artifactId>*</artifactId>
        </exclusion>
    </exclusions>       
</dependency>
