java.io.FileNotFoundException: /target/test.log (No such file or directory)

so any ideas, how to solve this exception ?

Do you have a /target directory at root? If not, try creating one. The logger is expecting to be able to create a file in that directory, and if it doesn't exist there's a problem.

If you are starting up a broker, it is possible to have that issue.

I found a bug report in ActiveMQ bug tracking site related with this issue.

Activeio test package inclusion and logging properties: https://issues.apache.org/jira/browse/AMQ-1132

I excluded org.apache.activemq:activeio-core to remove test-jar from dependencies and resolved this issue. That might help you too.

Hey I had this issue again, and I would like to reply with what I did which is exactly what @lemiorhan suggested. I'll improve upon his answer by giving sample code. Simply add this after tag in org.apache.activemq dependency.

<exclusions>
    <exclusion>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activeio-core</artifactId>
    </exclusion>
