Gradle build failed - can't access the Maven project object model (POM) artifacts about kafka-monitor HOT 5 CLOSED

Tried the --offline option, after dropping the jars in various libraries. No luck.

@ibm4mb Are you building kafka-monitor on a machine with network access to maven repository? It seems that gradle is not able to fetch the jar from maven repository. In order to understand whether this is kafka-monitor's issue or the network connection issue, can you try compile Apache Kafka using gradle?

Thank you, so much for responding. I was able execute the Gradle build on on my windows personal computer that has network access. But wanted to execute an offline Gradle build on a Red Hat Enterprise Linux 7.x Virtual Machine that has no access to external network, and so I wrestled with offline Gradle build after downloading the JARs that the build process was complaining. When you have a couple of minutes, if you can kindly direct me to key instructions for offline Gradle build of the kafka-monitor that'd be fantastic. Thanks in advance.

@ibm4mb Sure thing. I am happy to help :)

We have tested kafka-monitor compilation and it should work with ./gradlew jar, as you can see in the README at https://github.com/linkedin/kafka-monitor. All quick-start instructions, including the steps to build kafka-monitor, are put in this README.

Thus it seems that you are observing these errors because you tried to build kafka-monitor as an offline Gradle build on a virtual machine. We haven't tested kafka-monitor in such an environment so I am not sure whether it is expected to work. But it seems to me that it should work in the same way as any other gradle-based project such as Apache Kafka. Therefore, I am wondering if you are able to build Apache Kafka or any other open source gradle-based project as offline Gradle build on that virtual machine. Can you try that?

@lindong28, yes you're right. The problem is with executing a successful offline Gradle build, on a VM, because the build process tries to access the JARs locally (not sure which directory). So the process stops when it can't find the dependencies.

First time around, the online Gradle build stopped when my machine couldn't access the 3rd party JARs such as the Maven repositories on the internet.

Ideally it would be nice to have instructions to do an offline build for using a Kafka cluster within the intranet.

Thank you
