maven, ear package 将依赖项放在 ear 和 web 模块下

maven, ear package put dependencies either under ear and web module

我有一个耳机模块，所以沉着：

耳朵 ejb 网页

我正在使用 maven 来管理包；每个模块都有自己的 pom.xml

现在假设耳机模块的pom.xml是这样的：

<dependencies>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>myproject-ejb</artifactId>
            <type>ejb</type>
        </dependency>

        <!-- Depend on the EJB module and WAR so that we can package them -->
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>myproject-web</artifactId>
            <type>war</type>
        </dependency>

<build>
    <finalName>${project.parent.artifactId}</finalName>
    <plugins>
        <!--EAR plugin: format of output file -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-ear-plugin</artifactId>
            <version>${version.ear.plugin}</version>
            <configuration>
                <!-- Tell Maven we are using Jakarta EE -->
                <version>8</version>
                <!-- Use Jakarta EE ear libraries as needed. Jakarta EE ear libraries
                    are in easy way to package any libraries needed in the ear, and automatically
                    have any modules (EJB-JARs and WARs) use them -->
                <defaultLibBundleDir>lib</defaultLibBundleDir>
                <modules>
                <!-- Default context root of the web app is /customers-web.
                    If a custom context root is needed, uncomment the following snippet to
                    register our War as a web module and set the contextRoot property -->
                <!--
                <webModule>
                    <groupId>${project.groupId}</groupId>
                    <artifactId>customers-web</artifactId>
                    <contextRoot>/customers</contextRoot>
                </webModule>
                -->
                </modules>
                <outputFileNameMapping>@{artifactId}@@{dashClassifier?}@.@{extension}@</outputFileNameMapping>
            </configuration>
        </plugin>
        <!-- The WildFly plug-in deploys your ear to a local JBoss EAP container. 
            Due to Maven's lack of intelligence with EARs we need to configure
            the WildFly Maven plug-in to skip deployment for all modules. We then enable
            it specifically in the ear module. -->
        <plugin>
            <groupId>org.wildfly.plugins</groupId>
            <artifactId>wildfly-maven-plugin</artifactId>
            <configuration>
                <skip>false</skip>
            </configuration>
        </plugin>
    </plugins>
</build>

.. 这是根

上的 pom.xml 
    <dependency>
        <groupId>org.burp</groupId>
        <artifactId>some-lib</artifactId>
        <scope>compile</scope>
    </dependency>

当我编译 ear 时，我可以看到一些-lib.jar 在 {root}/lib 和 myproject-web/WEB-INF/lib 上。

如何将所有依赖项仅放在 {root}/lib

你可以覆盖 war 模块中的依赖范围，比如：

<dependency>
    <groupId>org.burp</groupId>
    <artifactId>some-lib</artifactId>
    <scope>provided</scope>
</dependency>

也许使用 SkinnyWars 可以解决您的问题：

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <artifactId>maven-ear-plugin</artifactId>
        <version>2.9.1</version>
        <configuration>
          <defaultLibBundleDir>lib/</defaultLibBundleDir>
          <skinnyWars>true</skinnyWars>
        </configuration>
      </plugin>
    </plugins>
  </build>
  ...
</project>
