Pessoal, estou tentando converter alguns projetos que tenho para maven, mas está gerando diversos erros como: - ArtifactTransferException: Failure to transfer com.sun.jmx:jmxri:jar:1.2.1 from https://maven-repository.dev.java.net/nonav/repository was cached in the local repository, resolution will not be reattempted until the update interval of java.net has elapsed or updates are forced. Original error: Could not transfer artifact com.sun.jmx:jmxri:jar:1.2.1 from/to java.net (https://maven-repository.dev.java.net/nonav/repository): No connector available to access repository java.net (https://maven-repository.dev.java.net/nonav/repository) of type legacy using the available factories WagonRepositoryConnectorFactory
