hello, For my application I has to define the custom tasks, which likes this http://wiki.jboss.org/wiki/Wiki.jsp?page=CustomTasks Therefore I have downloaded the cvs source code and builded it.But it costs me 2 days time, and still doesn't work right. I did following steps: 1. Download the jbpm source code from cvs 2. Change the variables software.installation.dir, ant.home, jboss.home to suit to my local machine 3. Then build "ant get.dependencies", "ant install.jbpm.ant" and "ant", the first two builds are successful, but the third build was failed. BUILD FAILED D:\xxx\jbpmcvs\jbpm.3\build\build.xml:36: The following error occurred while executing this line: D:\xxx\jbpmcvs\jbpm.3\designer\jpdl\org.jbpm.gd.jpdl.build\build.xml:63: The following error occurred while executing this line: D:\xxx\jbpmcvs\jbpm.3\designer\jpdl\org.jbpm.gd.jpdl.build\build.xml:221: Warning: Could not find file D:\xxx\jbpmcvs\jbpm.3\designer\jpdl\org.jbpm.gd.jpdl.build\target\workspace\N.3.1.0.SP1\org.jbpm.gd.jpdl.feature-3.1.0.SP1.zip to copy. What did I do wrong? Sincere thanks for any help Fengzhi View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4113004#...
