Build solr with Maven
Hi
My company has just decided to use maven to build new projects, which then
includes building solr with maven too.
But then it has been decided that solr_home also should be installed within
the webapp someplace. But now I have got the problem that solr cant find
the config files and so on. I have come across some posts here and there
which says that solr_home should not be placed within the webapp.
Is that correct? If so, what are the reasons for it, and should it not work
at all?

Yes I figured my problem would be something like that. I'll try with the
catalina/tomcat home variables I think.
Thank you.

I think you need absolute path. But perhaps if $CATALINA_HOME or
$TOMCAT_HOME is set, you can use it with your path.Haven't tried it though..
In any case, you should quite easily be able to verify if relative paths can
be used. All you need to do is to get the work directory for the webapp and
reflect that with your variable. In any case I don't think you can use a
path relative to web.xml. I believe the work directory is somewhere else
than /WEB-INF/ and that is the dir you need to make your variable relative
to..

Tried that, but I guess I am doing it wrong somehow with the paths.
The home folder should be WEB-INF/solr inside the tomcat. But how would I
set that path correctly? Do I need to use absolute paths?

Well, it's got all to do with how we have decided the rest of our deployment
environment. So the point is basicly that there should be no configurations
to the tomcat because the webapp should know all it's settings and could
basicly be deployed to whatever tomcat without configuration. Also there
should be no configuration done outside the webapp.
That is basicly the rule that I have to live by, and I'm very thankful for
your solution here but a tomcat configuration is out of the question.
I was hoping there was some way to set this via mavens pom.xml or something
like that.

Is there any good reason for keeping solr_home within the webapp?
It should work, but I would not recommend it. Have you configured solr_home
somewhere?
One way in Tomcat is to do something like this:
--
<Context...>
<Environment name="solr/home" type="java.lang.String"
value="[your_solr_home]" override="true"/> </Context>
--
in either: $tomcat_home/conf/Catalina/localhost/solr.xml or in
$tomcat_home/conf/server xml.
A better solution would probably be a maven project, but with two modules.
This way you could build the modules together or individually. Then you can
make adjustments to the config and reload core's at will, a feature you
would lose with keeping solr_home within the webapp.
