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)。

Maven POM

<dependency>

  <artifactId>icefaces-ace</artifactId>

    <exclusion>
      <artifactId>javax.servlet-api</artifactId>
      <groupId>javax.servlet</groupId>
    </exclusion>
  </exclusions>

And added a dependency with provided scope

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.0.1</version>
  <scope>provided</scope>
</dependency>

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)

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。

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:

No repository found containing: org.eclipse.update.feature,org.eclipse.m2e.feature,1.3.1.20130219-1424

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

<artifactId/>在这两个地方都错了。

  • 标签排序约定(当然不是严格执行的)是按以下顺序定义工件和排除标签groupIdartifactId, version, type, classifier, scope。你的是artifactIdgroupId。为了便于阅读,我建议您更正这一点并遵循约定。

  • 更改您的排除项,如下所示:

    <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>
    
  • 将您的依赖项更改为:

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>

对我来说,这不是 Maven 问题。Maven 获得了提供的 servlet-api,但您不是通过 maven 部署或构建包,您只是使用 maven 编译(也许通过 m2e 进行)并通过 Eclipse 进行部署。m2e/eclipse 应该处理这个问题,但不是。

根据这个类似的线程,安装 m2e + m2e-extras 应该可以解决它。另请参阅其他答案以获取有关 Eclipse 行为的更多详细信息。

我正在使用 Eclipse Juno 并安装“m2e - wtp”插件也解决了我的问题。
