Gradle build crashes when network is disabled

Help/Discuss
1

I have a build machine with super restricted network access (network access is not allowed), so gradle build crashes (stack trace below).

I tried to provide --offline flag, but it didn’t help.
Build command: gradle assemble --offline
Gradle version: 2.10

Any help is much appreciated

This is happening due to the Gradle daemon trying to bind to a local address. If you don’t have local permissions to bind to any network interfaces then you cannot use the daemon unfortunately. You can perhaps try running with --no-daemon.

That said, other issues will arise like executing tests or forked compilation, which are also done in an external process which the main build needs to communicate with. I’d suggest, if possible, relaxing these restrictions to at least allow applications to listen on the loopback interface.

Tried to use --no-daemon flag - previous error is gone now, but I’m not sure I understand stack trace now… It seems like Gradle is still trying to start a daemon process… :

gradle assemble --offline --no-daemon

Looks like there are some custom JVM arguments configured somewhere (probably a gradle.properties file or environment variable) that is causing Gradle to fork a separate build process.

Unfortunately, Gradle’s operation is highly dependent network access (at least via the loopback interface). All interprocess communication is done this way and most builds have at least a few worker process involved. There really isn’t a good solution for this besides relaxing the security on the box to at least allow communication over the loopback interface.
