Issues building Hazelcast with Maven

[Марио Павлов]

Hello,

I have an issue to build my project that depends on Hazelcast and I cannot quite figure out what is the reeason for the problem.

Locally I can build my project, and there are no issues at all. Here is the dependency tree of the project:
[INFO] --- dependency:2.8:tree (default-cli) @ tt-hazelcast ---
[INFO] <project-name>:jar:2014.3
[INFO] +- <internal-project>:<dependency>:jar:2014.3:compile

And here is the POM dependency section

        </dependency>

    </dependencies>

However, when I try to run a build on a Jenkins server (running on CentOS) I receive the following error:

-------------------------------------------------------

-------------------------------------------------------

I have manually installed both Hazelcast and Protobuf dependencies on the Jenkins machine, and I cannot find in the dependencies of the Hazelcast Core library that I'm adding anywhere references to the Protobuf-BOM. So I'm a little bit lost why this happens and what is the issue behind it. 

Thanks for the assist in advance :)

Hi Mario,
hazelcast is a child module of the hazelcast-root, which imports the
protobuf-bom.
Check the https://repo1.maven.org/maven2/com/hazelcast/hazelcast-root/5.2.1/hazelcast-root-5.2.1.pom

You can try to prepare a Maven repo on an internet-connected machine
and then copy the repo folder to your Jenkins.

Run:
mvn dependency:go-offline -Dmaven.repo.local=/tmp/repo

Then copy the /tmp/repo to the target machine's ~/.m2/repository.

Regards,
-- Josef
