Since this morning I have a very serious problem, from pom file http://repo2.maven.org/maven2/jasperreports/jasperreports/3.0.0/jasperreports-3.0.0.pom I read that you put your repository: <repositories> − <repository> <id>jaspersoft</id> <url>http://www.jasperforge.org/maven2</url> </repository> </repositories> when I compile my project, it creates a file maven-metadata-jaspersoft.xml directory under the commons-collections ... it should includes this file: <? Xml version = "1.0" encoding = "UTF-8"?> <metadata> <groupId> commons-collections </ groupId> <artifactId> commons-collections </ artifactId> </ Metadata> instead contains a standard error page (see attachment)... I believe in your repository, there are no more 'common-collections and other dependencies? please, it blocks the build!
