Hi there, I am following the installation guide here: http://hudson.jboss.org/hudson/job/jBPM5-release/lastSuccessfulBuild/artifact/target/jbpm-5.0.0-docs-build/jbpm-docs/html/ch02.html
however, I got an error when I executed the command line: ant start.demo, the error is:
c:\jbpm-installer\build.xml:297: Error while expanding C:\jbpm-installer\lib\jbpm-5.1-SNAPSHOT-gwt-console.zip
java.io.IOException: Negative seek offset
the xml 297 line is referred to gwt-console installation
Anyone know how solve the error?
