I installed Maven, and implemented command as you mentioned. Then it began to download jar files. But there are many files can not be downloaded, such as: Javadoc for some artifacts is not available. List of artifactswithout a javadoc archive:    oorg.jbpm:jbpm-bpmn2:5.0-20110217.064747-146    oorg.jbpm:jbpm-flow-builder:5.0-20110217.064747-147    oorg.jbpm:jbpm-flow:5.0-20110217.064747-147    oorg.drools:drools-api:5.2.0.M1    o org.drools:drools-core:5.2.0.M1    oorg.drools:drools-compiler:5.2.0.M1    oorg.antlr:antlr-runtime:3.2 ... and so on. Then when I import the project, it works. But after compile it, error comes: http://community.jboss.org/servlet/JiveServlet/showImage/105-5474-11516/2... http://community.jboss.org/servlet/JiveServlet/downloadImage/105-5474-115... Is there any steps that I missed? Thank you so much for helping me :) Best Regards, Shanshan --------------------------------------------------
