I have read where many people were able to solve this by:

• Deleting the folder from the local repository and letting it re-download it (this did not work)

• By configuring eclipse to target your maven installation instead of the embedded one as described here (this did not work)

  Could not calculate build plan :artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.4.3 is not available in the local repository

I am new to Maven so please excuse any of my ignorance

This project is working on another machine, and just pulled it down from the repository on this one, with the same version of eclipse and m2e plugin installed. I have been fooling with this for over 10 hours now and it is driving me nuts (Maven has been nothing but headaches for me so far...) Any help is tremendously appreciated! Thanks in advance!

EDIT

After looking closer I did notice that it is not downloading the .jar files into the local repository... I am not sure if that is something obvious...

EDIT

I am not given the option to add Maven Dependencies to the build path.

Answer 1

It appears that there can be a lot of different causes for this issue. I experienced it after installing a new version of Eclipse (Luna). Command-line maven worked fine, but Eclipse had build issues.

I use a Certificate Authority in my JRE. This is important because this provides my authentication when downloading Maven resources. Even though my project was pointing to the appropriate JRE inside of Eclipse - Eclipse was running using a different JRE (this is apparent looking at the Java process properties in Windows task manager). My solution was to add the following in my eclipse.ini and explicitly define the JRE I want to use.

-vm
C:\Program Files\Java\jdk1.7.0_51\bin\javaw.exe 

Answer 2

Some files where missing at your local repository. Usually under ${user.home}/.m2/repository/

Neets answer solves the problem. However if you dont want do download all the dependencies to your local repository again you could add the missing dependency to a project of yours and compile it.

Use the maven repository website to find the dependency. In your case http://mvnrepository.com/artifact/org.apache.maven.plugins/maven-resources-plugin/2.5 was missing.

Copy the listed XML to the pom.xml file of your project. In this case

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.5</version>
</dependency>

Run mvn compile in the root folder of the pom.xml. Maven will download all missing dependencies. After the download you can remove the added dependency.

Now you should be able to import the maven project or update the project without the error.

Answer 3

Try downloading a different version of maven. I had the same problem with maven 3.5.2 , I solved my problem just downloading maven 3.0.4

Answer 4

Very old stuff.

Got it solved fixing the localRepository in settings.xml. This file was copied from my other computer and the path of the .m2 repository wasn't the same.

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <localRepository>C:\Users\foo\.m2</localRepository>

</settings>

Answer 5

I handled my problem by adding bluesky to all-themes

<dependency>
   <groupId>org.primefaces.themes</groupId>
   <artifactId>all-themes</artifactId>
   <version>1.0.xx</version>
</dependency>

Answer 6

I was getting the same issue.

I just installed the m2e (Maven2Eclipse)plugin from below site:

http://www.eclipse.org/m2e/

Eclipse>Help>Install New Software>Available Software Sites>Add

Name: m2e (any name is OK)
Location:m2e - http://download.eclipse.org/technology/m2e/releases/

Under Install Window> Work with:

Select this new location and Add all the plugins that appear. Eclipse restart and it was running properly with no previous errors.
