Question

我已经从svn检查了一个项目。我正在尝试使用maven构建项目。

使用mvn compile构建它。

当我尝试命令mvn包时，我收到以下错误。

我发现这是因为，web.xml没有提供给pom.xml。

我已经尝试了堆栈中的答案中给出的所有方法。但似乎没有任何效果

这是我的pom.xml

Answer 1

默认情况下，此插件需要构建路径中存在WEB-INF / web.xml。如果您没有，请设置以下属性以避免错误

failOnMissingWebXml = false  //case sensitive, default value is true

实施例

<project>
...
 <build>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.5</version>  // Must use 2.1-alpha-2+
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
  </plugin>
 </build>
</project>

创建虚拟web.xml文件不是解决此问题的简洁方法。 apache documentation

中提供了更多配置

Answer 2

日志已经非常清楚了

我猜您的pom.xml配置如下：

<packaging>war</packaging>

以某种方式打包的War必须有WEB-INF / web.xml文件，您必须在webapp目录中手动添加WEB-INF目录和web.xml文件。

Answer 3

我遇到了同样的问题并通过修改pom.xml

修复了它

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