java我无法使用apachemaven3构建项目。2.2

Question

我无法使用ApacheMaven3.2.2构建项目，因为我对maven不熟悉，所以无法找到问题所在。请提供一些解决方案

错误如下：

[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]     Unresolveable build extension: Plugin 
  org.apache.maven.wagon:wagon-ftp:1.0-beta-2 or one of its dependencies could 
  not be resolved: Failed to read artifact descriptor for 
  org.apache.maven.wagon:wagon-ftp:jar:1.0-beta-2: Could not transfer artifact
  org.apache.maven.wagon:wagon-ftp:pom:1.0-beta-2 from/to central 
  (http://repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host 
  repo.maven.apache.org -> [Help 2]

我的maven版本如下：

C:\Users\xyz>mvn -version
Apache Maven 3.2.2 (45f7c06d68e745d05611f7fd14efb6594181933e; 2014-06-17T19:21:42+05:30)

Answer 1

问题在于你的maven路径，你必须把bin作为你的maven路径

Answer 2

在你的pom里。xml，尝试查找此依赖项

<dependency>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-ftp</artifactId>
<version>1.0-beta-2</version>
</dependency>

您可以使用以下工件来更改它

<dependency>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-ftp</artifactId>
<version>2.10</version>
</dependency>

如图纳基所说，如果它不起作用，问题在于你的互联网设置
