'on new Maven Project: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6?
I'm using Spring Tool Suite, with embebbed maven, I get this problem creating a new Maven Project. I have tried every answer given in similar posts; cleaning repository and rebuilding, proxies in settings.xml, pointing to the correct xml, using own maven and so on, what am i doing wrong? Full description of the problem:
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-
resources-plugin:2.6 or one of its dependencies could not be resolved:
Failed to read artifact descriptor for org.apache.maven.plugins:maven-
resources-plugin:jar:2.6
Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its
dependencies could not be resolved: Failed to read artifact descriptor for
org.apache.maven.plugins:maven-resources-plugin:jar:2.6

Solution 1:[1]
you need to add maven-resources-plugin plugin, you can fine code below:
<build>
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.7</version>
</plugin>
</plugins>
</pluginManagement>
</build>
add below code into settins.xml:
<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<username>optional-proxyUser</username>
<password>optional-proxyPassword</password>
<host>proxy.host.net</host>
<port>80</port>
<nonProxyHosts>some.demo.com</nonProxyHosts>
</proxy>
after this add settings.xml into project: goto Preferences>Maven>User-Settings>select your settings.xml and click apply and ok.

I deleted the repository folder [found here ~/.m2/repository] and after that it worked for me.
