RuntimeException: org/zeromq/ZMQ

[Scott Walter]

I'm trying to use a library that includes the jzmq library. IntelliJ doesn't notice any problems with my usages of that library and the code builds fine with "atlas-run". However, when the hook plugin that includes this code is run, I get a run time exception referencing zeromq. Here's the stack trace:

It seems that the atlassian SDK is incapable of finding the zeromq libraries, so I tried to add the the location of the libraries to my PATH variable, but that didn't seem to make a difference. Any ideas?

Thanks!

I defined my dependencies like this and then it worked:

<dependency>
    <groupId>org.zeromq</groupId>
    <artifactId>jeromq</artifactId>
    <version>0.3.3</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.3.0</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.3.0</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>org.bouncycastle</groupId>
    <artifactId>bcpkix-jdk15on</artifactId>
    <version>1.50</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>org.functionaljava</groupId>
    <artifactId>functionaljava</artifactId>
    <version>3.1</version>
    <scope>runtime</scope>
</dependency>

The key was stating the scope as runtime.

I don't think I defined it at all. Here's what I did exactly: 1. I cloned this: https://github.com/fedora-infra/fedmsg-java 2. I built it to generate a .jar for source, doc, and classes. 3. I imported all of those .jars into IntelliJ, and all of my references to the classes that I was using from that library worked. 4. Built it with atlassian-sdk 5. Runtime exception I'll look into defining dependencies in the pom.xml

Hi Scott,

how did you define the dependency on the ZeroMQ library in your pom?

Cheers,

Stefan
