Question

I am unable to build the project using Apache-maven 3.2.2 and As i am new to the maven i am not able to find the issue. Please provide some solutions to resolve it.

And the error as follows:

[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]

and my maven version as follows:

C:\Users\xyz>mvn -version

Answer 1

The problem is with your maven path , you have to give bin as your maven path

Answer 2

In your pom.xml, try to find this dependency.

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

and you can change it with the following artifact;

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

if it does not work, the problem is with your internet settings, as Tunaki said.
