ipv6 and ofbiz

[Woyce Batkins <my...@gmail.com>]

I tried to install ofbiz on ubuntu 20 and it runs by default on ipv6 (based
on netstat)
ofbiz release 17.12.6
Openjdk 8
embedded gradlew

 setting the following prevented gradle to connect to the daemon:
*-Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Addresses=false*

Any idea?

I think it starts in dual stack mode so you should be able to connect 
via IPV4 as well (localhost/127.0.0.1).

I think Gradle starts OFBiz into a forked JVM ( a different process than 
gradle jvm).

So you should configure gradle to pass the system properties to the 
forked JVM.


See in build.gradle createOfbizCommandTask that start ofbiz and uses 
JavaExec task [1].

You should pass systemProperties [2] to it.

def createOfbizCommandTask(taskName, arguments) {
     task(type: JavaExec, dependsOn: classes, taskName) {
         jvmArgs(application.applicationDefaultJvmArgs)
         classpath = sourceSets.main.runtimeClasspath
         main = application.mainClassName
         args arguments
         if (taskName ==~ /^ofbiz.*(--test|-t).*/) {
             finalizedBy(createTestReports)
         }
     }
}


Hope it helps and please tell us if you fixed your issue.
