java - Maven 包在没有 web.xml 的情况下仍然失败，即使有错误的

问题描述

我一直在努力从我的 Java Web 项目中删除 web.xml 文件并切换到基于 Java 的配置。该应用程序在 Eclipse 上没有 web.xml 时运行良好，但是当我尝试使用 Maven 打包它时，我收到如下所示的错误。

首先，我只是尝试将 maven-war-plugin 的版本设置为 >3。这并没有解决问题。我还尝试编辑项目 pom 以包含以下标签：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>3.0.0</version>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
            </configuration>
        </plugin>
    </plugins>
</build>

但是，我继续遇到以前遇到的相同错误：

Failed to execute goal org.apache.maven.plugins:maven-war-plugin:3.0.0:war (default-war) on project myproject-web: The specified web.xml file 'I:\myproject\web\src\main\webapp\WEB-INF\web.xml' does not exist -> [Help 1]

完整跟踪：

除了将 failOnMissingWebXml 标记设置为 false 之外，还有其他方法可以解决此错误吗？
