也许不是Maven问题。 m2e / wtp问题,也许吧?
为了给出背景知识,我在Eclipse中设置了一个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。我错过了什么吗?我怎样让Maven做对了?
在项目中, javax.servlet-api.jar 作为ICEFaces的传递依赖项被拉入。由于Tomcat附带了自己的servlet-api.jar,因此我将其标记为已排除并添加了显式依赖项(范围:已提供)。

设定:

*启用并配置了JSF和ICEFaces方面
*配置Eclipse项目的部署程序集以部署Maven依赖项
*从Eclipse部署项目到Tomcat(右键单击服务器选项卡&gt;添加/删除&gt;添加项目&gt; Publsh)
*更新1 *

不知道如何处理这些警告。我将查看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指向的帖子的答案中添加了链接检查了更新。 Eclipse显示有一个小的更新( 1.3.1.20130219-1424 )。但更新失败,出现以下错误:

所以,我卸载了现有的m2e并重新安装了它。这很有效。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 :(
(免责声明:这是我的理解。很高兴得到纠正)
似乎已经安装了m2e + m2e附加功能(不确定它们是否仍然是单独的实体,或者只是m2e)。我必须安装m2e - wtp connector才能正常工作。 Maven范围现在很荣幸。
安装m2e-wtp连接器:在Juno - Window&gt;偏好&gt; Maven&gt;发现&gt;打开目录&gt;选中m2e-wtp连接器的复选框以进行安装。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
答案 0 :(得分:0)
您的<artifactId/>
在两个地方都有误。
标签排序约定(当然不严格执行)是按以下排序groupId
,artifactId
,version
定义工件和排除标签,type
,classifier
,scope
。你的是artifactId
,groupId
。为了便于阅读,我建议你更正并遵循惯例。
按如下方式更改您的排除:
<dependency>
<groupId>org.icefaces</groupId>
<artifactId>icefaces-ace</artifactId>
<version>3.2.0</version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
将您的依赖关系更改为:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
答案 1 :(得分:0)
对我而言,这不是Maven问题。 Maven得到了servlet-api,但是你没有通过maven部署或构建一个包,你只是用maven编译(也许通过m2e编译)并通过Eclipse进行部署。 m2e / eclipse应该处理这个问题但不是。
根据这个similar thread,安装m2e + m2e-extras应该修复它。另请参阅其他答案以获取有关Eclipse行为的更多详细信息。
答案 2 :(得分:0)
我正在使用Eclipse Juno并安装“m2e-wtp”插件也解决了我的问题。
