how to set environment variables
hi,
I've already read a lot about this
seems, that it's not possible to set env-vars in a pom.xml or
profiles.xml file in maven 2
is that correct?
does anyone know a workaround or a mini-plugin that allows to set those
env vars?
TIA, martin

RE: how to set environment variables
Posted by mars1412 <ma...@gmail.com>.
seems there's really no easy way to set env vars directly
in general I think that this is ok and you should not set env vars directly,
but I have a good exception to this rule: it is described in the paragraph
"Using Saxon (but not as default)" of
http://martin-trummer.blogspot.com/2009/11/wysiwyg-gotchas.html Blog:
WYSIWYG gotchas
the solution I came up with is to write my own little mojo that I can pass
the env-vars I want to set.
I bind the plugin execution to the early validate phase and pass the
properties like this:
<configuration>
<environmentVariables>
<property>
<name>javax.xml.transform.TransformerFactory</name>
<value>com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl</value>
</property>
</environmentVariables>
</configuration>
in the mojo I simply call System.setProperty() for all given environment
vars - this works for my usecase.
However, beware that you should only use this if absolutely necessary

Good Afternoon Martin
i presume maven is called from a cmd/bash/cshell/kshell (shell environment) so one would need to reach back and change the configuration of the invoking parent environment
(which i dont how to accomplish from any child shell)
there are workarounds such as modifying the system registry to update and or insert new environment variables but one would need to reach back and refresh the configuration variables from the updated configuration..
interested in looking for a cleaner solution
any takers?
Martin

Those are Maven properties, not environment variables. You can't set
environment variables for the current process in Java at all, let alone
in Maven. If you're forking a new process, you may be able to set
environment variables on the subprocess via ProcessBuilder.

As you can see we are using 4 environment settings. In each one, we load
a different properties file to filter recources.
