如何在 Maven ear build 中删除库？

Question

我有 3 个项目。第一个读取数据库并为我的 ejbs 创建所有 class 文件。第二个是我的ejbs。第三个是我的 .ear 项目，它应该将第二个项目中的 ejb .jar 打包到 .ear 中。

项目 1 工作正常并且运行作为 java 应用程序。

项目 2 工作正常，并且有几个 Maven 运行配置，一个用于创建客户端 jar，一个用于将这些客户端 jar 部署到 Nexus，一个用于创建将打包到的 ejb .jar部署到服务器的 .ear。

项目 3 是个问题。过去，我只是在 eclipse 中导出了 .ear，而且效果很好。现在我正试图让它与 Maven 一起工作。我基本上已经可以正常工作了，但是它一直包含一堆库文件，而且它正在复制错误的文件。

这是pom

            <configuration>
                <earSourceDirectory>EarContent</earSourceDirectory>
                <modules>

            </configuration>
        </plugin>
    </plugins>
</build>
</project>

第二个项目有一个运行配置，用于创建 ejb .jar 并将其命名为 kdsSession.jar

        <plugin>
            <artifactId>maven-ejb-plugin</artifactId>
            <version>3.0.0</version>
            <configuration>
                <jarName>kdsSession</jarName>
                <outputDirectory>${basedir}</outputDirectory>
                <ejbVersion>3.1</ejbVersion>
                <archive>
                    <manifestEntries>
                        <Dependencies>org.apache.commons.lang3</Dependencies>
                    </manifestEntries>
                </archive>
            </configuration>
        </plugin>

我想在我的 .ear 中使用那个 jar。以下是ear项目的输出。

如您所见，它出于某种原因正在复制一些库文件。我不想要那些。它也没有得到预先存在的 kdsSession.jar，而是创建一个新的

我该如何纠正这种行为？

Answer 1

在你耳边的项目运行mvn dependency:tree

查看它并尝试找出不需要的 jar 的来源。

也许您在 kds-ejb 项目中声明了依赖项。如果是这种情况，请将范围设置为提供。
