Question

i've a maven based project and i'm trying to import it to Spring source tool suite. I am getting the following error.

Description Resource    Path    Location    Type
Could not calculate build plan: Missing:
----------
1) org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.4.2

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=org.apache.maven.plugins -DartifactId=maven-resources-plugin -Dversion=2.4.2 -Dpackaging=maven-plugin -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there: 
      mvn deploy:deploy-file -DgroupId=org.apache.maven.plugins -DartifactId=maven-resources-plugin -Dversion=2.4.2 -Dpackaging=maven-plugin -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

----------
1 required artifact is missing.

for artifact: 
  org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.4.2

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

It looks like it's asking me to install the maven resourource plugin 2.4.2 but I'm not sure what is the file to download. I tried downloading maven-plugin-plugin-2.4.2-source.jar and feeding it to the command; but it didn't work. I then went to the maven repository in http://svn.apache.org/viewvc/maven/plugins/tags/maven-resources-plugin-2.4.2/ and downloaded the pof.xml; this also is not working. If you have seen this problem before pls help me understand what is missing / or what the error message is.

Thanks,

You may be behind firewall. You could try to set an HTTP proxy to bypass the firewall.

In Windows, this file is located at: C:\\Documents and Settings\\<windows Login>\\.m2\\settings.xml

You need to provide valid parameters to the <proxy> based on how the network is setup in your organization.

<settings 
...
     <proxies>

    <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>put-ur-proxy-servername</host>
      <port>80</port>
    </proxy>
...
</settings>
