我为Eclipse安装了M2Eclipse Plug-In。我对maven不太熟悉。我的问题是我无法下载两个文物：

    13.07.10 08:53:30 MESZ: Build errors for test; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project test: Missing:

----------
2 required artifacts are missing.

for artifact: 
  de.studi:Studentenportal:pom:0.0.1-SNAPSHOT

from the specified remote repositories:
  central (http://repo1.maven.org/maven2, releases=true, snapshots=false)

这是我的POM.XML：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

      <version>2.5</version>
    </dependency>
  </dependencies>
  <build>
   <finalName>test</finalName>
  </build>
</project>

我尝试使用几个版本的JSF2但没有成功。

我在pom.xml中添加了以下内容：

<repositories>
    <repository>
      <id>maven2-repository.dev.java.net</id>
      <name>Java.net Repository for Maven</name>
      <url>http://download.java.net/maven/2/</url>
      <layout>default</layout>
    </repository>
</repositories>

但问题仍然存在。那有什么不对吗？

好的，我明白了！该项目可以建立。不幸的是我不知道为什么。我没有改变一些东西:-)

现在我只收到Maven的警告：

它看起来并不那么好 - 尤其是失踪的POM警告令人焦虑。

更新

首先我将其更改为myfaces，然后将相应的存储库添加到.m2目录中的settings.xml。像那样：

<profile>
  <id>jdk-1.6</id>

  <activation>
    <jdk>1.6</jdk>
  </activation>

  <repositories>
        <repository>
        <id>JBOSS</id>
        <name>JBoss Repository</name>
        <url>http://repository.jboss.org/maven2/</url>
    </repository>
  </repositories>
</profile>

但是仍然存在maven无法找到工件的问题。请帮助： - ）

2 个答案:

答案 0 :(得分：4)

你的groupId依赖是错误的。输入mvnrepository并在那里查找您的依赖项。

com.sun.faces应该是javax.faces（版本号也可能是错的）

如果你从某个博客或网页获得了这种依赖性，试着找出从哪里下载它。

答案 1 :(得分：0)

您的pom.xml及其父级，以及settings.xml中定义的maven存储库列表中都没有，您可以访问这些工件。

通常情况下，遇到这类问题时，我的第一步是检查mvnbrowser可用工件的位置。对于jsf-api，回复为quite simple：您必须将JavaNet存储库添加到您的pom.xml repositories。
