m2e: convert project to maven project
m2e, m2eclipse, maven
Solution
You should actually remove all libs you have in `WEB-INF/lib` directory and add adequate `dependency` declarations in the POM. `WEB-INF` directory itself (and other web resources) should stay in `src/main/webapp`. If you have some non-Java files in `WEB-INF/classes`, move them into `src/main/resources`. After all, do Maven build on console by `mvn clean package` and tell if it works. It should. Then regenerate Eclipse project files by `Maven -> Update Project Configuration...`.
I don't believe in such tools for automagic migration of freestyle (mostly Ant) projects into Maven. As I see, it does nothing more that generate almost plain POM.
Problem
I'm trying to start with maven using `m2e plugin` for eclipse. But if I try to change existing project to Maven project (`Configure/Convert to Maven Project`), result is: Multiple annotations found at this line: - Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.4.3 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-resources-plugin:pom:2.4.3 from/to central (http://repo1.maven.org/maven2): Connect times out - Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (execution: default-compile, phase: compile) - 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://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.

Where could be the problem?
