Error running mvn package for jeromq: "Bind Cannot assign requested address: connect"

I want to send and receive data from Matlab and MetaTrader 5 on Windows 10. According to this post, JeroMQ is the easiest route to go:

I cloned the repo from https://github.com/zeromq/jeromq
I installed maven
Then I went into the repository root and start building it using: mvn package, which produced the following error message:

 [ERROR] Failures:
 [ERROR] TestEvents.testEventConnectRetried:85 No event was received
 [ERROR] Errors:

 [ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.1:test (default-test) on project jeromq: There are test failures.

I tried to fix this by setting the IP configuration for the localhost to 127.0.0.1 according to these posts:

which did not fix the problem (same error message).

I think it is related to some IP settings, but I am new to socket communication. I have no experience in Java programming/debugging. Please help me to fix this, so the .jar file is built successfully and I can add it to my javaclasspath in Matlab.

Otherwise: Is there an (easy) alternative way to establish Matlab socket communication with other programs (e.g. via ZeroMQ)?

Solution

I had the same problem, to bypass the tests, you need to add some code to the pom.xml file which is at the main folder jeromq-masters.

So the part that I changed is below. You can compare with your own pom and change it according to it. Since a couple of days passed, I dont exactly remember the part that I added,but starting with "includes" must be the part that I added.

<groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.1</version>
    <configuration>
      <useSystemClassLoader>false</useSystemClassLoader>
      <includes>
        <include>TestFail.java</include>
      </includes>
      <testFailureIgnore>true</testFailureIgnore>
    </configuration>

Then you need to recompile it with mvn package command.

This allowed me to compile the JAR file.
