Maven error "Failure to transfer..."

Question

I am trying to set up a project using Maven (m2eclipse), but I get this error in Eclipse:

Description Resource Path Location Type Could not calculate build plan: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:2.0.2 from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:2.0.2 from/to central (http://repo1.maven.org/maven2): No response received after 60000 ExampleProject Unknown Maven Problem

Any ideas? It would be helpful if you could show me how to check if everything is configured fine...

Answer 1

Remove all your failed downloads:

find ~/.m2  -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \; 

For windows:

cd %userprofile%\.m2\repository for /r %i in (*.lastUpdated) do del %i 

Then rightclick on your project in eclipse and choose Maven->"Update Project ...", make sure "Update Dependencies" is checked in the resulting dialog and click OK.
