Hi,
This is how we solved this problem:
On the Jenkins buildserver we added the following to our settings.xml
<profiles>
<profile>
<id>jenkins</id>
<properties>
<port>600${EXECUTOR_NUMBER}</port> <!-- port could be for any
plugin, so not really a good name -->
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>jenkins</activeProfile>
</activeProfiles>
This assumes a maximum of 10 executors on the buildserver.
Now you don't have to specify the port on the commandline, it'll be picked
up from these settings.
I'm not sure anymore if we had to expose these JENKINS variables and if it
had to be prefixed with "env.", but this should be enough info to solve
your problem.

Hi,
I need to pass the contents of a file as the value of a command-line
parameter when invoking a maven goal.
Why?
The maven goal I am calling would trigger a server process on a certain
port. This goal will be setup in a Jenkins build as a continuous
integration
test job. And there could be more than one such jenkins job. So I want to
ensure that each server process starts on a different port.
I have scanned for an available port in a "pre-build" step and have
written
the identified port to a file port.txt and have ensured that it is
available
in the Jenkins job's workspace before the Maven build is triggered.
What I want to do now is specify a maven goal like below within the
Jenkins
job I'm writing:
integration-test clean install -Dport=$(<port.txt)
Assuming that port.txt only contains a string like "6001", the above
command
should (at runtime) become:
integration-test clean install -Dport=6001
And when the job runs, a client should connect a url constructed as
below:
http://localhost:6001/web_service/myapp
Note that the port in the above URL is taken from incoming command-line
parameter 'port'.
However, when I configured this into Jenkins, the job failed with the
stacktrace containg the below:
Caused by: java.net.URISyntaxException: Illegal character in authority at
index 7: http://localhost:$(<port.txt)/web_service/myapp
I am executing the job on Linux and have verified that $(<..) is
supported
on the version of the shell that I am running. So I think replacing
$(<port.txt) with `cat port.txt` is not the answer that might help me.
The problem seems to be lying in the way I'm using the maven
command-line.
Looks like the shell is passing everything it sees on the command-line to
Maven which has no clue how to handle it!
Hope I made the problem clear. All help is appreciated.
