The POM for org.apache.maven.plugins:maven-war-plugin:jar:3.0 is missing, no dependency information available

Question

I got this error in my maven project, which I'm not able to solve.
How can I solve it?

I tried all possible things with right click on project .
Update project, Download Source, ... ).

And I got slf4j-api-1.6.1.jar in Maven depencies.
Why does it fail on load ?

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
    SLF4J: Defaulting to no-operation (NOP) logger implementation
    SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Answer 1

The problem you have is simply that no version 3.0 of the maven-war-plugin exists.

The most recent version of maven-war-plugin is 2.6
