Because the OVA is 10GB size, seems until be propagated to the mirrors will not be available. We ignore how much time will take it. If passed some days the problem has not been solved we'll open an issue in sourceforge.net or looking for another way for sharing the file.
As we explain here
https://docs.openkm.com/kcenter/view/wf ... g-ide.html we offer 3 ways, OpenKM portable, configure eclipse plugin or jboss developer studio 5.x. I suggest OpenKM portable or configure eclipse plugin, why ? because work with latest eclipse have some advantatges rather used 4-5 years old eclipse what comes with jboss developer studio 5
OpenKM portable was the first aproach to offering quick environment for working, but it have several problems. The most relevant issue in eclipse portable is that is 32 bits architecture and needs JVM 32 bits ( what comes into portable as embeded JDK ), otherwise eclipse portable does not starting. But really when eclipse portable is running you would like to work with 64 bits, that means you also will configure at your own side 64 bits JDK, etc... that's why we decided moving to OVA, where we can setup full environment with database, tomcat, latest eclipse with jbpm plugin, git, jdk, etc... yet ready to be used.
