maven issue ArtifactDescriptorException

Question

I am trying the Spring REST example exaplained here. The project source is here here.

I unzipped the file and renamed top folder to 'myproject' and imported it into eclipse as an existing maven project. But, observed that lot of compilation issues due to missing spring jars. I guess this is because maven is not able to import these jars. When I check the pom.xml, I see eclipse is complaining with below errors:

ArtifactDescriptorException: Failed to read artifact descriptor for com.fasterxml.jackson.core:jackson-databind:jar:2.2.2: ArtifactResolutionException: Failure to transfer com.fasterxml.jackson.core:jackson-databind:pom:2.2.2 from http://repo.maven.apache.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 com.fasterxml.jackson.core:jackson-databind:pom:2.2.2 from/to central (http://repo.maven.apache.org/maven2): connection timed out to http://repo.maven.apache.org/maven2/com/fasterxml/jackson/core/jackson-databind/2.2.2/jackson-databind-2.2.2.pom

and

ArtifactDescriptorException: Failed to read artifact descriptor for com.fasterxml.jackson.core:jackson-databind:jar:2.2.2: ArtifactResolutionException: Failure to transfer com.fasterxml.jackson.core:jackson-databind:pom:2.2.2 from http://repo.maven.apache.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.

I am new to maven so struggling here. Please help me how to fix it.

Thank you.

Answer 1

For me, it was because Eclipse was caching the exception. Try to:

right click on project -> maven -> update-project -> force to update snapshot/release -> OK.

It worked for me for the same problem.
