WFLYPRT0023: Could not connect to remote+http://127.0.0.1:9990. The connection timed out - maven

Question

I am testing jax-rs web services with Arquillian, and I use an embedded Wildfly 10 container. This is my pom.xml:
..

</build>
..
with arquillian.xml in src/test/resources:
<arquillian xmlns="http://jboss.org/schema/arquillian"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://jboss.org/schema/arquillian http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
<container qualifier="wildfly10" default="true">
<configuration>
<property name="jbossHome">target/wildfly-10.1.0.Final/</property>
<property name="modulePath">target/wildfly-10.1.0.Final/modules</property>
</configuration>
</container>
..
But when type: mvn clean verify, I get the following error:
WFLYPRT0023: Could not connect to remote+http://127.0.0.1:9990. The connection timed out

Answer 1

This question was one of the first links I found in Google about error WFLYPRT0023.
I got the same error code when connecting via jboss-cli and fixed it by setting the time-out on the command line.
The default time-out is 5000 milliseconds which doesn't seem to be nearly enough, especially when the network is slow.
This sets the time-out to 30 seconds
jboss-cli.bat --timeout=30000 ...
As far as setting this in Arquillian is concerned, you should be able to add the
startupTimeoutInSeconds
property in your
arquillian.xml
file. I assume that this setting is the same as the one above.
There is some more information about Arquillian here Arquillian and Wildfly: set timeout for management connection
