那时也许不是 Maven 问题。m2e / wtp 问题,也许?
只是为了提供背景,我在 Eclipse 中建立了一个 ICEFaces 项目,并将其部署在 Tomcat 7.0.30 中。在部署到 Tomcat 时,似乎忽略了 servlet-api.jar 的 Maven POM 配置在提供的范围内。我错过了什么吗?我如何让 Maven 做对?
在项目中, javax.servlet-api.jar作为 ICEFaces 的传递依赖项被引入。由于 Tomcat 带有它自己的 servlet-api.jar,我将其标记为被排除并添加了显式依赖项(范围:提供)。

设置:
* Eclipse Juno
* Maven webapp 项目已创建。
* JSF 和 ICEFaces 方面已启用和配置。
* 配置 Eclipse 项目的部署程序集以部署 Maven 依赖项。
* 将项目从 Eclipse 部署到 Tomcat(右键单击服务器选项卡 > 添加/删除 > 添加项目 > 发布)
* 更新 1 *
mvn 依赖:tree -Dverbose
不知道如何处理这些警告。我将查找如何启用调试日志记录。

* 更新 2 *
我在 Juno 中安装了以下版本:
m2e - Maven Integration for Eclipse 1.3.0.**20130129-0926** org.eclipse.m2e.feature.feature.group Eclipse.org - m2e
在@eis 所指向的帖子的答案中添加了链接检查更新。Eclipse 显示有一个小更新可用(1.3.1.20130219-1424)。但是更新失败并出现以下错误:

所以,我卸载了现有的 m2e 并重新安装了它。这行得通。还包括
m2e - slf4j over logback logging (Optional) 1.3.1.20130219-1424 org.eclipse.m2e.logback.feature.feature.group Eclipse.org - m2e
但问题仍然存在。Juno 仍在部署 javax.servlet-api3.0.1.jar :(
解决了
(首先免责声明:这是我的理解。很高兴得到纠正)
似乎 m2e + m2e extras(不确定它们是否仍然是单独的实体,或者只是 m2e)已经随 Juno 一起安装了。我必须安装m2e - wtp 连接器才能正常工作。Maven 范围现在受到尊重。
安装 m2e-wtp 连接器:在 Juno - Window > Preferences > Maven > Discovery > Open Catalog > 选中 m2e-wtp 连接器的复选框以安装它。这会将以下内容添加到已安装的软件中
m2e-wtp - Maven Integration for WTP (Incubation) 0.17.0.20130212-1821 org.eclipse.m2e.wtp.feature.feature.group Eclipse.org - m2e-wtp
