Working on the sample "Developing with Eclipse", I get the following messages at the very beginning, when creating the Maven project. I don't know Maven at all, so I have no clue what to do about this error:
CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:2.3.2: ArtifactResolutionException: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:2.3.2 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 org.apache.maven.plugins:maven-compiler-plugin:pom:2.3.2 from/to central (http://repo.maven.apache.org/maven2): null to http://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-compiler-plugin/2.3.2/m aven-compiler-plugin-2.3.2.pom
Until now I didn't do much: Just install m2e and create a project with the 4 parameters (group-id, id, name and decription) as described on the page. Thats it.
Any help appreciated.
brgds,
