插件 org.apache.maven.plugins:maven-install-plugin:2.4 或其依赖项之一无法解析

Question

I am getting this error message and a further one here: Failed to read artifact descriptor for org.apache.maven.plugins:maven-install-plugin:jar:2.4:

Even though when i go the .m2 repository with this path C:\\Users\\A591024.m2\\repository\\org\\apache\\maven\\plugins\\maven-resources-plugin\\2.4

the maven-resources-plugin-2.4.jar file is there AND maven-resources-plugin-2.4.pom is also there. i have tried to delete the .m2 repository with no luck. so far maven will not build my project that i desperately need it to.

any ideas?

Answer 1

it seems proxy issue please aad following in your setting.xml by grabbing LAN setting and proxy information.

<proxies>
      <proxy>
        <id>proxy</id>
        <active>true</active>
        <protocol>http</protocol>
        <host>HOSTNAME</host>
        <port>PORT</port>
      </proxy>
  </proxies>

This is a frequent issue, please see the below link as well.

Plugin org.apache.maven.plugins:maven-install-plugin:2.4 or one of its dependencies could not be resolved

Answer 2

Errors might be something like

• Could not resolve org.apache.maven.plugins:maven-clean-plugin:2.4.1
• error : (groupId):(artifactID):(version)

In dependencies section pom.xml , put

<dependency>
    <groupId>(groupId)</groupId>    
    <artifactId>(artifactID) </artifactId>  
    <version>(version)</version>
    <type>maven-plugin</type> // here type will be whatever the groupId is 
</dependency>    

Result will be then this dependency for above error

<dependency>
    <groupId>org.apache.maven.plugins</groupId>    
    <artifactId>maven-install-plugin</artifactId>  
    <version>2.4</version>
    <type>maven-plugin</type>
</dependency>

Reload build and this should download the dependencies for those unresolved errors.
